Installation Guide This guide will help you install and set up the Prometheus MCP Server. ## Prerequisites - Python 3.10 or higher - Access to a Prometheus server - [uv](https://github.com/astral-sh/uv) package manager (recommended) ## Installation Options ### Option 1: Direct Installation 1. Clone the repository: ```bash git clone https://github.com/pab1it0/prometheus-mcp-server.git cd prometheus-mcp-server ``` 2. Create and activate a virtual environment: ```bash # Using uv (recommended) uv venv source .venv/bin/activate # On Unix/macOS .venv\Scripts\activate # On Windows # Using venv (alternative) python -m venv venv source venv/bin/activate # On Unix/macOS venv\Scripts\activate # On Windows ``` 3. Install the package: ```bash # Using uv (recommended) uv pip install -e . # Using pip (alternative) pip install -e . ``` ### Option 2: Using Docker 1. Clone the repository: ```bash git clone https://github.com/pab1it0/prometheus-mcp-server.git cd prometheus-mcp-server ``` 2. Build the Docker image: ```bash docker build -t prometheus-mcp-server . ``` ## Configuration 1. Create a `.env` file in the root directory (you can copy from `.env.template`): ```bash cp .env.template .env ``` 2. Edit the `.env` file with your Prometheus server details: ```env # Required: Prometheus configuration PROMETHEUS_URL=http://your-prometheus-server:9090 # Optional: Authentication credentials (if needed) # Choose one of the following authentication methods if required: # For basic auth PROMETHEUS_USERNAME=your_username PROMETHEUS_PASSWORD=your_password # For bearer token auth PROMETHEUS_TOKEN=your_token # Optional: Custom MCP configuration # PROMETHEUS_MCP_SERVER_TRANSPORT=stdio # Choose between http, stdio, sse. If undefined, stdio is set as the default transport. # Optional: Only relevant for non-stdio transports # PROMETHEUS_MCP_BIND_HOST=localhost # if undefined, 127.0.0.1 is set by default. # PROMETHEUS_MCP_BIND_PORT=8080 # if undefined, 8080 is set by default. ``` ## Running the Server ### Option 1: Directly from Python After installation and configuration, you can run the server with: ```bash # If installed with -e flag python -m prometheus_mcp_server.main # If installed as a package prometheus-mcp-server ``` ### Option 2: Using Docker ```bash # Using environment variables directly docker run -it --rm \ -e PROMETHEUS_URL=http://your-prometheus-server:9090 \ -e PROMETHEUS_USERNAME=your_username \ -e PROMETHEUS_PASSWORD=your_password \ prometheus-mcp-server # Using .env file docker run -it --rm \ --env-file .env \ prometheus-mcp-server # Using docker-compose docker-compose up ``` ## Verifying Installation When the server starts successfully, you should see output similar to: ``` Loaded environment variables from .env file Prometheus configuration: Server URL: http://your-prometheus-server:9090 Authentication: Using basic auth Starting Prometheus MCP Server... Running server in standard mode... ``` The server is now ready to receive MCP requests from clients like Claude Desktop. ``` -------------------------------------------------------------------------------- /.github/workflows/claude-code-review.yml: -------------------------------------------------------------------------------- ```yaml name: Claude Code Review on: pull_request: types: [opened, synchronize] # Optional: Only run on specific file changes # paths: # - "src/**/*.ts" # - "src/**/*.tsx" # - "src/**/*.js" # - "src/**/*.jsx" jobs: claude-review: # Optional: Filter by PR author # if: | # github.event.pull_request.user.login == 'external-contributor' || # github.event.pull_request.user.login == 'new-developer' || # github.event.pull_request.author_association == 'FIRST_TIME_CONTRIBUTOR' runs-on: ubuntu-latest permissions: contents: read pull-requests: read issues: read id-token: write actions: read # Required for Claude to read CI results on PRs steps: - name: Checkout repository uses: actions/checkout@v4 with: fetch-depth: 1 - name: Run Claude Code Review id: claude-review uses: anthropics/claude-code-action@beta with: claude_code_oauth_token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }} # This is an optional setting that allows Claude to read CI results on PRs additional_permissions: | actions: read # Optional: Specify model (defaults to Claude Sonnet 4, uncomment for Claude Opus 4.1) # model: "claude-opus-4-1-20250805" # Direct prompt for automated review (no @claude mention needed) direct_prompt: | Please review this pull request and provide feedback on: - Code quality and best practices - Potential bugs or issues - Performance considerations - Security concerns - Test coverage Be constructive and helpful in your feedback. # Optional: Use sticky comments to make Claude reuse the same comment on subsequent pushes to the same PR # use_sticky_comment: true # Optional: Customize review based on file types # direct_prompt: | # Review this PR focusing on: # - For TypeScript files: Type safety and proper interface usage # - For API endpoints: Security, input validation, and error handling # - For React components: Performance, accessibility, and best practices # - For tests: Coverage, edge cases, and test quality # Optional: Different prompts for different authors # direct_prompt: | # ${{ github.event.pull_request.author_association == 'FIRST_TIME_CONTRIBUTOR' && # 'Welcome!

These can be set directly in your environment or through a `.env` file in the project root directory. ### Required Variables | Variable | Description | Example | |----------|-------------|--------| | `PROMETHEUS_URL` | URL of your Prometheus server | `http://prometheus:9090` | ### Authentication Variables Prometheus MCP Server supports multiple authentication methods. Choose the appropriate one for your Prometheus setup: #### Basic Authentication | Variable | Description | Example | |----------|-------------|--------| | `PROMETHEUS_USERNAME` | Username for basic authentication | `admin` | | `PROMETHEUS_PASSWORD` | Password for basic authentication | `secure_password` | #### Token Authentication | Variable | Description | Example | |----------|-------------|--------| | `PROMETHEUS_TOKEN` | Bearer token for authentication | `eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...` | ## Authentication Priority If multiple authentication methods are configured, the server will prioritize them in the following order: 1. Bearer token authentication (if `PROMETHEUS_TOKEN` is set) 2. Basic authentication (if both `PROMETHEUS_USERNAME` and `PROMETHEUS_PASSWORD` are set) 3. No authentication (if no credentials are provided) #### MCP Server Configuration | Variable | Description | Example | |----------|-------------|--------| | `PROMETHEUS_MCP_SERVER_TRANSPORT` | Choose between these transports: `http`, `stdio`, `sse`. If undefined, `stdio` is set as the default transport. | `http` | | `PROMETHEUS_MCP_BIND_HOST` | Define the host for your MCP server, if undefined, `127.0.0.1` is set by default. | `localhost` | | `PROMETHEUS_MCP_BIND_PORT` | Define the port where your MCP server is exposed, if undefined, `8080` is set by default. | `8080` | ## MCP Client Configuration ### Claude Desktop Configuration To use the Prometheus MCP Server with Claude Desktop, you'll need to add configuration to the Claude Desktop settings: ```json { "mcpServers": { "prometheus": { "command": "uv", "args": [ "--directory", "<full path to prometheus-mcp-server directory>", "run", "src/prometheus_mcp_server/main.py" ], "env": { "PROMETHEUS_URL": "http://your-prometheus-server:9090", "PROMETHEUS_USERNAME": "your_username", "PROMETHEUS_PASSWORD": "your_password" } } } } ``` ### Docker Configuration with Claude Desktop If you're using the Docker container with Claude Desktop: ```json { "mcpServers": { "prometheus": { "command": "docker", "args": [ "run", "--rm", "-i", "-e", "PROMETHEUS_URL", "-e", "PROMETHEUS_USERNAME", "-e", "PROMETHEUS_PASSWORD", "prometheus-mcp-server" ], "env": { "PROMETHEUS_URL": "http://your-prometheus-server:9090", "PROMETHEUS_USERNAME": "your_username", "PROMETHEUS_PASSWORD": "your_password" } } } } ``` ## Network Connectivity Ensure that the environment where the Prometheus MCP Server runs has network access to your Prometheus server. If running in Docker, you might need to adjust network settings or use host networking depending on your setup. ## Troubleshooting ### Connection Issues If you encounter connection issues: 1. Verify that the `PROMETHEUS_URL` is correct and accessible from the environment where the MCP server runs 2. Check that authentication credentials are correct 3. Ensure no network firewalls are blocking access 4. Verify that your Prometheus server is running and healthy ### Authentication Issues If you experience authentication problems: 1. Double-check your username and password or token 2. Ensure the authentication method matches what your Prometheus server expects 3. Check Prometheus server logs for authentication failures ``` -------------------------------------------------------------------------------- /docs/usage.md: -------------------------------------------------------------------------------- ```markdown # Usage Guide This guide explains how to use the Prometheus MCP Server with AI assistants like Claude. ## Available Tools The Prometheus MCP Server provides several tools that AI assistants can use to interact with your Prometheus data: ### Query Tools #### `execute_query` Executes an instant PromQL query and returns the current value(s). **Parameters:** - `query`: PromQL query string (required) - `time`: Optional RFC3339 or Unix timestamp (defaults to current time) **Example Claude prompt:** ``` Use the execute_query tool to check the current value of the 'up' metric. ``` #### `execute_range_query` Executes a PromQL range query to return values over a time period. **Parameters:** - `query`: PromQL query string (required) - `start`: Start time as RFC3339 or Unix timestamp (required) - `end`: End time as RFC3339 or Unix timestamp (required) - `step`: Query resolution step width (e.g., '15s', '1m', '1h') (required) **Example Claude prompt:** ``` Use the execute_range_query tool to show me the CPU usage over the last hour with 5-minute intervals. Use the query 'rate(node_cpu_seconds_total{mode="user"}[5m])'. ``` ### Discovery Tools #### `list_metrics` Retrieves a list of all available metric names. **Example Claude prompt:** ``` Use the list_metrics tool to show me all available metrics in my Prometheus server. ``` #### `get_metric_metadata` Retrieves metadata about a specific metric. **Parameters:** - `metric`: The name of the metric (required) **Example Claude prompt:** ``` Use the get_metric_metadata tool to get information about the 'http_requests_total' metric. ``` #### `get_targets` Retrieves information about all Prometheus scrape targets. **Example Claude prompt:** ``` Use the get_targets tool to check the health of all monitoring targets. ``` ## Example Workflows ### Basic Monitoring Check ``` Can you check if all my monitored services are up? Also, show me the top 5 CPU-consuming pods if we're monitoring Kubernetes. ``` Claude might use: 1. `execute_query` with `up` to check service health 2. `execute_query` with a more complex PromQL query to find CPU usage ### Performance Analysis ``` Analyze the memory usage pattern of my application over the last 24 hours. Are there any concerning spikes? ``` Claude might use: 1. `execute_range_query` with appropriate time parameters 2. Analyze the data for patterns and anomalies ### Metric Exploration ``` I'm not sure what metrics are available. Can you help me discover metrics related to HTTP requests and then show me their current values? ``` Claude might use: 1. `list_metrics` to get all metrics 2. Filter for HTTP-related metrics 3. `get_metric_metadata` to understand what each metric represents 4. `execute_query` to fetch current values ## Tips for Effective Use 1. **Be specific about time ranges** when asking for historical data 2. **Specify step intervals** appropriate to your time range (e.g., use smaller steps for shorter periods) 3. **Use metric discovery tools** if you're unsure what metrics are available 4. **Start with simple queries** and gradually build more complex ones 5. **Ask for explanations** if you don't understand the returned data ## PromQL Query Examples Here are some useful PromQL queries you can use with the tools: ### Basic Queries - Check if targets are up: `up` - HTTP request rate: `rate(http_requests_total[5m])` - CPU usage: `sum(rate(node_cpu_seconds_total{mode!="idle"}[5m])) by (instance)` - Memory usage: `node_memory_MemTotal_bytes - node_memory_MemFree_bytes - node_memory_Buffers_bytes - node_memory_Cached_bytes` ### Kubernetes-specific Queries - Pod CPU usage: `sum(rate(container_cpu_usage_seconds_total{container!="POD",container!=""}[5m])) by (pod)` - Pod memory usage: `sum(container_memory_working_set_bytes{container!="POD",container!=""}) by (pod)` - Pod restart count: `kube_pod_container_status_restarts_total` ## Limitations - The MCP server queries your live Prometheus instance, so it only has access to metrics retained in your Prometheus server's storage - Complex PromQL queries might take longer to execute, especially over large time ranges - Authentication is passed through from your environment variables, so ensure you're using credentials with appropriate access rights ``` -------------------------------------------------------------------------------- /.github/workflows/ci.yml: -------------------------------------------------------------------------------- ```yaml name: CI/CD on: push: branches: [ "main" ] tags: - 'v*' pull_request: branches: [ "main" ] env: REGISTRY: ghcr.io IMAGE_NAME: ${{ github.repository }} jobs: ci: name: CI runs-on: ubuntu-latest timeout-minutes: 10 permissions: contents: read packages: write steps: - name: Checkout repository uses: actions/checkout@v4 - name: Set up Python 3.12 uses: actions/setup-python@v5 with: python-version: "3.12" - name: Install uv uses: astral-sh/setup-uv@v4 with: enable-cache: true - name: Create virtual environment run: uv venv - name: Install dependencies run: | source .venv/bin/activate uv pip install -e ".[dev]" - name: Run tests with coverage run: | source .venv/bin/activate pytest --cov --junitxml=junit.xml -o junit_family=legacy --cov-report=xml --cov-fail-under=89 - name: Upload coverage to Codecov uses: codecov/codecov-action@v4 with: file: ./coverage.xml fail_ci_if_error: false - name: Upload test results to Codecov if: ${{ !cancelled() }} uses: codecov/test-results-action@v1 with: file: ./junit.xml token: ${{ secrets.CODECOV_TOKEN }} - name: Build Python distribution run: | python3 -m pip install build --user python3 -m build - name: Store the distribution packages uses: actions/upload-artifact@v4 with: name: python-package-distributions path: dist/ - name: Set up QEMU uses: docker/setup-qemu-action@v3 - name: Set up Docker Buildx uses: docker/setup-buildx-action@v3 - name: Log in to the Container registry if: github.event_name != 'pull_request' uses: docker/login-action@v3 with: registry: ${{ env.REGISTRY }} username: ${{ github.actor }} password: ${{ secrets.GITHUB_TOKEN }} - name: Extract metadata (tags, labels) for Docker id: meta uses: docker/metadata-action@v5 with: images: ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }} tags: | type=ref,event=branch type=ref,event=pr type=semver,pattern={{version}} type=semver,pattern={{major}}.{{minor}} type=semver,pattern={{major}} type=sha,format=long - name: Build and push Docker image uses: docker/build-push-action@v5 with: context: . push: ${{ github.event_name != 'pull_request' }} tags: ${{ steps.meta.outputs.tags }} labels: ${{ steps.meta.outputs.labels }} platforms: linux/amd64,linux/arm64 cache-from: type=gha cache-to: type=gha,mode=max deploy: name: Deploy if: startsWith(github.ref, 'refs/tags/v') && github.event_name == 'push' needs: ci runs-on: ubuntu-latest timeout-minutes: 15 environment: name: pypi url: https://pypi.org/p/prometheus_mcp_server permissions: contents: write #

This guide focuses specifically on deploying the Prometheus MCP server, which allows AI agents to query Prometheus metrics. ## Prerequisites Before you begin, make sure you have: - A Kubernetes cluster - Helm (v3.10 minimum, v3.14+ recommended) - kubectl - A Prometheus instance running in your cluster For detailed instructions on setting up a Kubernetes cluster and installing the Toolhive operator, refer to the [Toolhive Kubernetes Operator Tutorial](https://codegate-docs-git-website-refactor-stacklok.vercel.app/toolhive/tutorials/toolhive-operator). ## Deploying the Prometheus MCP Server ### Step 1: Install the Toolhive Operator Follow the instructions in the [Toolhive Kubernetes Operator Tutorial](https://codegate-docs-git-website-refactor-stacklok.vercel.app/toolhive/tutorials/toolhive-operator) to install the Toolhive operator in your Kubernetes cluster. ### Step 2: Create the Prometheus MCP Server Resource Create a YAML file named `mcpserver_prometheus.yaml` with the following content: ```yaml apiVersion: toolhive.stacklok.dev/v1alpha1 kind: MCPServer metadata: name: prometheus namespace: toolhive-system spec: image: ghcr.io/pab1it0/prometheus-mcp-server:latest transport: stdio port: 8080 permissionProfile: type: builtin name: network podTemplateSpec: spec: containers: - name: mcp securityContext: allowPrivilegeEscalation: false runAsNonRoot: false runAsUser: 0 runAsGroup: 0 capabilities: drop: - ALL resources: limits: cpu: "500m" memory: "512Mi" requests: cpu: "100m" memory: "128Mi" env: - name: PROMETHEUS_URL value: "http://prometheus-server.monitoring.svc.cluster.local:80" # Default value, can be overridden securityContext: runAsNonRoot: false runAsUser: 0 runAsGroup: 0 seccompProfile: type: RuntimeDefault resources: limits: cpu: "100m" memory: "128Mi" requests: cpu: "50m" memory: "64Mi" ``` > **Important**: Make sure to update the `PROMETHEUS_URL` environment variable to point to your Prometheus server's URL in your Kubernetes cluster. ### Step 3: Apply the MCP Server Resource Apply the YAML file to your cluster: ```bash kubectl apply -f mcpserver_prometheus.yaml ``` ### Step 4: Verify the Deployment Check that the MCP server is running: ```bash kubectl get mcpservers -n toolhive-system ``` You should see output similar to: ``` NAME STATUS URL AGE prometheus Running http://prometheus-mcp-proxy.toolhive-system.svc.cluster.local:8080 30s ``` ## Using the Prometheus MCP Server with Copilot Once the Prometheus MCP server is deployed, you can use it with GitHub Copilot or other AI agents that support the Model Context Protocol. ### Example: Querying Prometheus Metrics When asking Copilot about Prometheus metrics, you might see responses like: **Query**: "What is the rate of requests on the Prometheus server?" **Response**: ```json { "resultType": "vector", "result": [ { "metric": { "__name__": "up", "instance": "localhost:9090", "job": "prometheus" }, "value": [ 1749034117.048, "1" ] } ] } ``` This shows that the Prometheus server is up and running (value "1"). ## Troubleshooting If you encounter issues with the Prometheus MCP server: 1. Check the MCP server status: ```bash kubectl get mcpservers -n toolhive-system ``` 2. Check the MCP server logs: ```bash kubectl logs -n toolhive-system deployment/prometheus-mcp ``` 3. Verify the Prometheus URL is correct in the MCP server configuration. 4. Ensure your Prometheus server is accessible from the MCP server pod. ## Configuration Options The Prometheus MCP server can be configured with the following environment variables: - `PROMETHEUS_URL`: The URL of your Prometheus server (required) - `PORT`: The port on which the MCP server listens (default: 8080) ## Available Metrics and Queries The Prometheus MCP server provides access to all metrics available in your Prometheus instance. Some common queries include: - `up`: Check if targets are up - `rate(http_requests_total[5m])`: Request rate over the last 5 minutes - `sum by (job) (rate(http_requests_total[5m]))`: Request rate by job For more information on PromQL (Prometheus Query Language), refer to the [Prometheus documentation](https://prometheus.io/docs/prometheus/latest/querying/basics/). ## Conclusion By following this guide, you've deployed a Prometheus MCP server in your Kubernetes cluster using the Toolhive operator. This server allows AI agents like GitHub Copilot to query your Prometheus metrics, enabling powerful observability and monitoring capabilities through natural language. ``` -------------------------------------------------------------------------------- /.github/ISSUE_TEMPLATE/question.yml: -------------------------------------------------------------------------------- ```yaml name: ❓ Question or Support description: Ask a question or get help with configuration/usage title: "[Question]: " labels: ["type: question", "status: needs-triage"] assignees: [] body: - type: markdown attributes: value: | Thank you for your question!

Automated Workflows #### `bug-triage.yml` - Core Triage Automation - **Triggers**: Issue events (opened, edited, labeled, unlabeled, assigned, unassigned), issue comments, scheduled runs (every 6 hours), manual dispatch - **Functions**: - Auto-labels new issues based on content analysis - Assigns issues to maintainers based on component labels - Updates triage status when issues are assigned - Welcomes new contributors - Manages stale issues (marks stale after 30 days, closes after 7 additional days) - Links PRs to issues and updates status on PR merge #### `issue-management.yml` - Advanced Issue Management - **Triggers**: Issue events, comments, daily scheduled runs, manual dispatch - **Functions**: - Enhanced auto-triage with pattern matching - Smart assignment based on content and labels - Issue health monitoring and escalation - Comment-based automated responses - Duplicate detection for new issues #### `label-management.yml` - Label Consistency - **Triggers**: Manual dispatch, weekly scheduled runs - **Functions**: - Synchronizes label schema across the repository - Creates missing labels with proper colors and descriptions - Audits and reports on unused labels - Migrates deprecated labels to new schema #### `triage-metrics.yml` - Reporting and Analytics - **Triggers**: Daily and weekly scheduled runs, manual dispatch - **Functions**: - Collects comprehensive triage metrics - Generates detailed markdown reports - Tracks response times and resolution rates - Monitors triage efficiency and quality - Creates weekly summary issues ### 2. Issue Templates #### Bug Report Template (`bug_report.yml`) Comprehensive template for bug reports including: - Pre-submission checklist - Priority level classification - Detailed reproduction steps - Environment information (OS, Python version, Prometheus version) - Configuration and log collection - Component classification #### Feature Request Template (`feature_request.yml`) Structured template for feature requests including: - Feature type classification - Problem statement and proposed solution - Use cases and technical implementation ideas - Breaking change assessment - Success criteria and compatibility considerations #### Question/Support Template (`question.yml`) Template for questions and support requests including: - Question type classification - Experience level indication - Current setup and attempted solutions - Urgency level assessment ### 3. Label Schema The system uses a hierarchical label structure: #### Priority Labels - `priority: critical` - Immediate attention required - `priority: high` - Should be addressed soon - `priority: medium` - Normal timeline - `priority: low` - Can be addressed when convenient #### Status Labels - `status: needs-triage` - Issue needs initial triage - `status: in-progress` - Actively being worked on - `status: waiting-for-response` - Waiting for issue author - `status: stale` - Marked as stale due to inactivity - `status: in-review` - Has associated PR under review - `status: blocked` - Blocked by external dependencies #### Component Labels - `component: prometheus` - Prometheus integration issues - `component: mcp-server` - MCP server functionality - `component: deployment` - Deployment and containerization - `component: authentication` - Authentication mechanisms - `component: configuration` - Configuration and setup - `component: logging` - Logging and monitoring #### Type Labels - `type: bug` - Something isn't working as expected - `type: feature` - New feature or enhancement - `type: documentation` - Documentation improvements - `type: performance` - Performance-related issues - `type: testing` - Testing and QA related - `type: maintenance` - Maintenance and technical debt #### Environment Labels - `env: windows` - Windows-specific issues - `env: macos` - macOS-specific issues - `env: linux` - Linux-specific issues - `env: docker` - Docker deployment issues #### Difficulty Labels - `difficulty: beginner` - Good for newcomers - `difficulty: intermediate` - Requires moderate experience - `difficulty: advanced` - Requires deep codebase knowledge ## Automation Rules ### Auto-Labeling Rules 1. **Priority Detection**: - `critical`: Keywords like "critical", "crash", "data loss", "security" - `high`: Keywords like "urgent", "blocking" - `low`: Keywords like "minor", "cosmetic" - `medium`: Default for other issues 2. **Component Detection**: - `prometheus`: Keywords related to Prometheus, metrics, PromQL - `mcp-server`: Keywords related to MCP, server, transport - `deployment`: Keywords related to Docker, containers, deployment - `authentication`: Keywords related to auth, tokens, credentials 3. **Type Detection**: - `feature`: Keywords like "feature", "enhancement", "improvement" - `documentation`: Keywords related to docs, documentation - `performance`: Keywords like "performance", "slow" - `bug`: Default for issues not matching other types ### Assignment Rules Issues are automatically assigned based on: - Component labels (all components currently assign to @pab1it0) - Priority levels (critical issues get immediate assignment with notification) - Special handling for performance and authentication issues ### Stale Issue Management 1. Issues with no activity for 30 days are marked as `stale` 2. A comment is added explaining the stale status 3. Issues remain stale for 7 days before being automatically closed 4. Stale issues that receive activity have the stale label removed ### PR Integration 1. PRs that reference issues with "closes #X" syntax automatically: - Add a comment to the linked issue - Apply `status: in-review` label to the issue 2. When PRs are merged: - Add resolution comment to linked issues - Remove `status: in-review` label ## Metrics and Reporting ### Daily Metrics Collection - Total open/closed issues - Triage status distribution - Response time averages - Label distribution analysis ### Weekly Reporting Comprehensive reports include: - Overview statistics - Triage efficiency metrics - Response time analysis - Label distribution - Contributor activity - Quality metrics - Actionable recommendations ### Health Monitoring The system monitors: - Issues needing attention (>3 days without triage) - Stale issues (>30 days without activity) - Missing essential labels - High-priority unassigned issues - Potential duplicate issues ## Manual Controls ### Workflow Dispatch Options #### Bug Triage Workflow - `triage_all`: Re-triage all open issues #### Label Management Workflow - `sync`: Create/update all labels - `create-missing`: Only create missing labels - `audit`: Report on unused/deprecated labels - `cleanup`: Migrate deprecated labels on issues #### Issue Management Workflow - `health-check`: Run issue health analysis - `close-stale`: Process stale issue closure - `update-metrics`: Refresh metric calculations - `sync-labels`: Synchronize label schema #### Metrics Workflow - `daily`/`weekly`/`monthly`: Generate period reports - `custom`: Custom date range analysis ## Best Practices ### For Maintainers 1. **Regular Monitoring**: - Check weekly triage reports - Review health check notifications - Act on escalated high-priority issues 2. **Label Hygiene**: - Use consistent labeling patterns - Run label sync weekly - Audit unused labels monthly 3. **Response Times**: - Aim to respond to new issues within 48 hours - Prioritize critical and high-priority issues - Use template responses for common questions ### For Contributors 1. **Issue Creation**: - Use appropriate issue templates - Provide complete information requested in templates - Check for existing similar issues before creating new ones 2. **Issue Updates**: - Respond promptly to requests for additional information - Update issues when circumstances change - Close issues when resolved independently ## Troubleshooting ### Common Issues 1. **Labels Not Applied**: Check if issue content matches pattern keywords 2. **Assignment Not Working**: Verify component labels are correctly applied 3. **Stale Issues**: Issues marked stale can be reactivated by adding comments 4. **Duplicate Detection**: May flag similar but distinct issues - review carefully ### Manual Overrides All automated actions can be manually overridden: - Add/remove labels manually - Change assignments - Remove stale status by commenting - Close/reopen issues as needed ## Configuration ### Environment Variables No additional environment variables required - system uses GitHub tokens automatically. ### Permissions Workflows require: - `issues: write` - For label and assignment management - `contents: read` - For repository access - `pull-requests: read` - For PR integration ## Monitoring and Maintenance ### Regular Tasks 1. **Weekly**: Review triage reports and health metrics 2. **Monthly**: Audit label usage and clean up deprecated labels 3. **Quarterly**: Review automation rules and adjust based on repository needs ### Performance Metrics - Triage time: Target <24 hours for initial triage - Response time: Target <48 hours for first maintainer response - Resolution time: Varies by issue complexity and priority - Stale rate: Target <10% of open issues marked as stale ## Future Enhancements Potential improvements to consider: 1. **AI-Powered Classification**: Use GitHub Copilot or similar for smarter issue categorization 2. **Integration with External Tools**: Connect to project management tools or monitoring systems 3. **Advanced Duplicate Detection**: Implement semantic similarity matching 4. **Automated Testing**: Trigger relevant tests based on issue components 5. **Community Health Metrics**: Track contributor engagement and satisfaction --- For questions about the triage automation system, please create an issue with the `type: documentation` label. ``` -------------------------------------------------------------------------------- /src/prometheus_mcp_server/server.py: -------------------------------------------------------------------------------- ```python #!/usr/bin/env python import os import json from typing import Any, Dict, List, Optional, Union from dataclasses import dataclass import time from datetime import datetime, timedelta from enum import Enum import dotenv import requests from fastmcp import FastMCP from prometheus_mcp_server.logging_config import get_logger dotenv.load_dotenv() mcp = FastMCP("Prometheus MCP") # Get logger instance logger = get_logger() # Health check tool for Docker containers and monitoring @mcp.tool(description="Health check endpoint for container monitoring and status verification") async def health_check() -> Dict[str, Any]: """Return health status of the MCP server and Prometheus connection.

STDIO Mode (Default) Best for local development and CLI integration: ```bash docker run --rm \ -e PROMETHEUS_URL=http://prometheus:9090 \ -e PROMETHEUS_MCP_SERVER_TRANSPORT=stdio \ mcp/prometheus-mcp-server:latest ``` ### 2. HTTP Mode Best for web applications and remote access: ```bash docker run --rm -p 8080:8080 \ -e PROMETHEUS_URL=http://prometheus:9090 \ -e PROMETHEUS_MCP_SERVER_TRANSPORT=http \ -e PROMETHEUS_MCP_BIND_HOST=0.0.0.0 \ -e PROMETHEUS_MCP_BIND_PORT=8080 \ mcp/prometheus-mcp-server:latest ``` ### 3. Server-Sent Events (SSE) Mode Best for real-time applications: ```bash docker run --rm -p 8080:8080 \ -e PROMETHEUS_URL=http://prometheus:9090 \ -e PROMETHEUS_MCP_SERVER_TRANSPORT=sse \ -e PROMETHEUS_MCP_BIND_HOST=0.0.0.0 \ -e PROMETHEUS_MCP_BIND_PORT=8080 \ mcp/prometheus-mcp-server:latest ``` ## Docker Compose Examples ### Basic Setup with Prometheus ```yaml version: '3.8' services: prometheus: image: prom/prometheus:latest ports: - "9090:9090" volumes: - ./prometheus.yml:/etc/prometheus/prometheus.yml prometheus-mcp-server: image: mcp/prometheus-mcp-server:latest depends_on: - prometheus environment: - PROMETHEUS_URL=http://prometheus:9090 - PROMETHEUS_MCP_SERVER_TRANSPORT=stdio restart: unless-stopped ``` ### HTTP Mode with Authentication ```yaml version: '3.8' services: prometheus: image: prom/prometheus:latest ports: - "9090:9090" command: - '--config.file=/etc/prometheus/prometheus.yml' - '--web.basic-auth-users=/etc/prometheus/web.yml' volumes: - ./prometheus.yml:/etc/prometheus/prometheus.yml - ./web.yml:/etc/prometheus/web.yml prometheus-mcp-server: image: mcp/prometheus-mcp-server:latest ports: - "8080:8080" depends_on: - prometheus environment: - PROMETHEUS_URL=http://prometheus:9090 - PROMETHEUS_USERNAME=admin - PROMETHEUS_PASSWORD=secretpassword - PROMETHEUS_MCP_SERVER_TRANSPORT=http - PROMETHEUS_MCP_BIND_HOST=0.0.0.0 - PROMETHEUS_MCP_BIND_PORT=8080 restart: unless-stopped healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8080/"] interval: 30s timeout: 10s retries: 3 start_period: 40s ``` ### Multi-tenant Setup ```yaml version: '3.8' services: prometheus-mcp-tenant1: image: mcp/prometheus-mcp-server:latest ports: - "8081:8080" environment: - PROMETHEUS_URL=http://prometheus:9090 - PROMETHEUS_TOKEN=${TENANT1_TOKEN} - ORG_ID=tenant-1 - PROMETHEUS_MCP_SERVER_TRANSPORT=http - PROMETHEUS_MCP_BIND_HOST=0.0.0.0 restart: unless-stopped prometheus-mcp-tenant2: image: mcp/prometheus-mcp-server:latest ports: - "8082:8080" environment: - PROMETHEUS_URL=http://prometheus:9090 - PROMETHEUS_TOKEN=${TENANT2_TOKEN} - ORG_ID=tenant-2 - PROMETHEUS_MCP_SERVER_TRANSPORT=http - PROMETHEUS_MCP_BIND_HOST=0.0.0.0 restart: unless-stopped ``` ### Production Setup with Secrets ```yaml version: '3.8' services: prometheus-mcp-server: image: mcp/prometheus-mcp-server:latest ports: - "8080:8080" environment: - PROMETHEUS_URL=http://prometheus:9090 - PROMETHEUS_MCP_SERVER_TRANSPORT=http - PROMETHEUS_MCP_BIND_HOST=0.0.0.0 secrets: - prometheus_token environment: - PROMETHEUS_TOKEN_FILE=/run/secrets/prometheus_token restart: unless-stopped deploy: resources: limits: memory: 256M cpus: '0.5' reservations: memory: 128M cpus: '0.25' secrets: prometheus_token: external: true ``` ## Production Deployment ### Resource Requirements #### Minimum Requirements - **CPU**: 0.1 cores - **Memory**: 64MB - **Storage**: 100MB (for container image) #### Recommended for Production - **CPU**: 0.25 cores - **Memory**: 128MB - **Storage**: 200MB ### Docker Compose Production Example ```yaml version: '3.8' services: prometheus-mcp-server: image: mcp/prometheus-mcp-server:latest ports: - "8080:8080" environment: - PROMETHEUS_URL=https://prometheus.example.com - PROMETHEUS_TOKEN_FILE=/run/secrets/prometheus_token - PROMETHEUS_MCP_SERVER_TRANSPORT=http - PROMETHEUS_MCP_BIND_HOST=0.0.0.0 - ORG_ID=production secrets: - prometheus_token restart: unless-stopped deploy: replicas: 2 resources: limits: memory: 256M cpus: '0.5' reservations: memory: 128M cpus: '0.25' restart_policy: condition: on-failure delay: 5s max_attempts: 3 window: 120s healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8080/"] interval: 30s timeout: 10s retries: 3 start_period: 40s logging: driver: "json-file" options: max-size: "100m" max-file: "3" secrets: prometheus_token: external: true ``` ### Kubernetes Deployment ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: prometheus-mcp-server labels: app: prometheus-mcp-server spec: replicas: 2 selector: matchLabels: app: prometheus-mcp-server template: metadata: labels: app: prometheus-mcp-server spec: containers: - name: prometheus-mcp-server image: mcp/prometheus-mcp-server:latest ports: - containerPort: 8080 env: - name: PROMETHEUS_URL value: "http://prometheus:9090" - name: PROMETHEUS_MCP_SERVER_TRANSPORT value: "http" - name: PROMETHEUS_MCP_BIND_HOST value: "0.0.0.0" - name: PROMETHEUS_TOKEN valueFrom: secretKeyRef: name: prometheus-token key: token resources: limits: memory: "256Mi" cpu: "500m" requests: memory: "128Mi" cpu: "250m" livenessProbe: httpGet: path: / port: 8080 initialDelaySeconds: 30 periodSeconds: 30 readinessProbe: httpGet: path: / port: 8080 initialDelaySeconds: 5 periodSeconds: 10 --- apiVersion: v1 kind: Service metadata: name: prometheus-mcp-server spec: selector: app: prometheus-mcp-server ports: - protocol: TCP port: 80 targetPort: 8080 type: ClusterIP ``` ## Security Considerations ### 1. Network Security ```yaml # Use internal networks for container communication version: '3.8' networks: internal: driver: bridge internal: true external: driver: bridge services: prometheus-mcp-server: networks: - internal - external # Only expose necessary ports externally ``` ### 2. Secrets Management ```bash # Create Docker secrets for sensitive data echo "your-prometheus-token" | docker secret create prometheus_token - # Use secrets in compose version: '3.8' services: prometheus-mcp-server: secrets: - prometheus_token environment: - PROMETHEUS_TOKEN_FILE=/run/secrets/prometheus_token ``` ### 3. User Permissions The container runs as non-root user `app` (UID 1000) by default. No additional configuration needed. ### 4. TLS/HTTPS ```yaml # Use HTTPS for Prometheus URL environment: - PROMETHEUS_URL=https://prometheus.example.com - PROMETHEUS_TOKEN_FILE=/run/secrets/prometheus_token ``` ## Monitoring and Health Checks ### Built-in Health Checks The Docker image includes built-in health checks: ```bash # Check container health docker ps # Look for "healthy" status # Manual health check docker exec <container-id> curl -f http://localhost:8080/ || echo "unhealthy" ``` ### Custom Health Check ```yaml healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8080/"] interval: 30s timeout: 10s retries: 3 start_period: 40s ``` ### Prometheus Metrics The server itself doesn't expose Prometheus metrics, but you can monitor it using standard container metrics. ### Logging ```yaml logging: driver: "json-file" options: max-size: "100m" max-file: "3" ``` View logs: ```bash docker logs prometheus-mcp-server docker logs -f prometheus-mcp-server # Follow logs ``` ## Troubleshooting ### Common Issues #### 1. Connection Refused ```bash # Check if Prometheus URL is accessible from container docker run --rm -it mcp/prometheus-mcp-server:latest /bin/bash curl -v http://your-prometheus:9090/api/v1/status/config ``` #### 2. Authentication Failures ```bash # Test authentication curl -H "Authorization: Bearer your-token" \ http://your-prometheus:9090/api/v1/status/config # Or with basic auth curl -u username:password \ http://your-prometheus:9090/api/v1/status/config ``` #### 3. Permission Errors ```bash # Check container user docker exec container-id id # Should show: uid=1000(app) gid=1000(app) ``` #### 4. Port Binding Issues ```bash # Check port availability netstat -tulpn | grep 8080 # Use different port docker run -p 8081:8080 ... ``` ### Debug Mode ```bash # Run with verbose logging docker run --rm \ -e PROMETHEUS_URL=http://prometheus:9090 \ -e PYTHONUNBUFFERED=1 \ mcp/prometheus-mcp-server:latest ``` ### Container Inspection ```bash # Inspect container configuration docker inspect prometheus-mcp-server # Check resource usage docker stats prometheus-mcp-server # Access container shell docker exec -it prometheus-mcp-server /bin/bash ``` ### Common Environment Variable Issues | Issue | Solution | |-------|----------| | `PROMETHEUS_URL not set` | Set the `PROMETHEUS_URL` environment variable | | `Invalid transport` | Use `stdio`, `http`, or `sse` | | `Invalid port` | Use a valid port number (1024-65535) | | `Connection refused` | Check network connectivity to Prometheus | | `Authentication failed` | Verify credentials or token | ### Getting Help 1. Check the [GitHub Issues](https://github.com/pab1it0/prometheus-mcp-server/issues) 2. Review container logs: `docker logs <container-name>` 3. Test Prometheus connectivity manually 4. Verify environment variables are set correctly 5. Check Docker network configuration For production deployments, consider implementing monitoring and alerting for the MCP server container health and performance. ```
