# Prometheus MCP Server
[](https://github.com/users/pab1it0/packages/container/package/prometheus-mcp-server)
[](https://github.com/pab1it0/prometheus-mcp-server/releases)
[](https://codecov.io/gh/pab1it0/prometheus-mcp-server)
[](https://github.com/pab1it0/prometheus-mcp-server/blob/main/LICENSE)
A [Model Context Protocol][mcp] (MCP) server for Prometheus.
This provides access to your Prometheus metrics and queries through standardized MCP interfaces, allowing AI assistants to execute PromQL queries and analyze your metrics data.
[mcp]: https://modelcontextprotocol.io
## Features
- [x] Execute PromQL queries against Prometheus
- [x] Discover and explore metrics
- [x] List available metrics
- [x] Get metadata for specific metrics
- [x] View instant query results
- [x] View range query results with different step intervals
- [x] Authentication support
- [x] Basic auth from environment variables
- [x] Bearer token auth from environment variables
- [x] Docker containerization support
- [x] Provide interactive tools for AI assistants
The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.
This is useful if you don't use certain functionality or if you don't want to take up too much of the context window.
## Getting Started
### Prerequisites
- Prometheus server accessible from your environment

"-i",
"--rm",
"-e",
"PROMETHEUS_URL",
"ghcr.io/pab1it0/prometheus-mcp-server:latest"
],
"env": {
"PROMETHEUS_URL": "<your-prometheus-url>"
}
}
}
}
```
</details>
<details>
<summary><b>Claude Code</b></summary>
Install via the Claude Code CLI:
```bash
claude mcp add prometheus --env PROMETHEUS_URL=http://your-prometheus:9090 -- docker run -i --rm -e PROMETHEUS_URL ghcr.io/pab1it0/prometheus-mcp-server:latest
```
</details>
<details>
<summary><b>VS Code / Cursor / Windsurf</b></summary>

## Coding Standards
Please follow these guidelines when writing code:
### Python Style Guide
- Follow [PEP 8](https://peps.python.org/pep-0008/) style guide
- Use meaningful variable and function names
- Write docstrings for all public modules, functions, classes, and methods
- Keep functions focused and single-purpose
- Maximum line length: 100 characters (when practical)
### Code Organization
- Place new functionality in appropriate modules
- Keep related code together
- Avoid circular dependencies
- Use type hints where appropriate
### Documentation
- Update the README.md if you change functionality
- Add docstrings to new functions and classes
- Comment complex logic or non-obvious implementations
- Keep comments up-to-date with code changes
### Commit Messages
Write clear, concise commit messages:
- Use the present tense ("Add feature" not "Added feature")
- Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
- Limit the first line to 72 characters or less
- Reference issues and pull requests when relevant
- For example:
```
feat: add support for custom headers in Prometheus requests
- Adds PROMETHEUS_CUSTOM_HEADERS environment variable
- Updates documentation with usage examples
- Includes tests for header validation
Fixes #106
```
## Testing Guidelines
All contributions must include appropriate tests. We use `pytest` for testing.
### Running Tests
```bash
# Run all tests
pytest
# Run with coverage report
pytest --cov=src --cov-report=term-missing
# Run specific test file
pytest tests/test_specific.py
# Run tests matching a pattern
pytest -k "test_pattern"
```
### Test Requirements
- **Write tests for new features** - All new functionality must have corresponding tests
- **Maintain code coverage** - Aim for 80%+ code coverage (enforced by CI)
- **Test edge cases** - Consider error conditions and boundary cases
- **Use meaningful test names** - Test names should describe what they're testing
- **Keep tests isolated** - Tests should not depend on each other
- **Mock external dependencies** - Use `pytest-mock` for mocking Prometheus API calls
### Test Structure
```python
def test_feature_description():
"""Test that feature does what it should."""
# Arrange - Set up test conditions
# Act - Execute the functionality being tested
# Assert - Verify the results
```
## Pull Request Process
1. **Update your fork** with the latest changes from `main`:
```bash
git fetch upstream
git rebase upstream/main
```
2. **Create a feature branch**:
```bash
git checkout -b feature/your-feature-name
```
3. **Make your changes** following the guidelines above
4. **Run tests locally**:
```bash
pytest --cov=src --cov-report=term-missing
```
5. **Push to your fork**:
```bash
git push origin feature/your-feature-name
```
6. **Create a Pull Request** with:
- A clear title describing the change
- A detailed description of what changed and why
- References to related issues (e.g., "Fixes #123")
- Screenshots or examples if applicable
7. **Address review feedback** - Be responsive to comments and suggestions
8. **Wait for CI/CD checks** - All automated checks must pass:
- Tests must pass
- Code coverage must meet minimum threshold (80%)
- No security vulnerabilities detected

## 🎯 Key Features Implemented
### 1. Intelligent Auto-Triage
- **Pattern-based labeling**: Analyzes issue content for automatic categorization
- **Priority detection**: Identifies critical, high, medium, and low priority issues
- **Component classification**: Routes issues to appropriate maintainers
- **Environment detection**: Identifies OS and platform-specific issues
### 2. Smart Assignment System
- **Component-based routing**: Auto-assigns based on affected components
- **Priority escalation**: Critical issues get immediate attention and notification
- **Load balancing**: Future-ready for multiple maintainers
### 3. Comprehensive Issue Templates
- **Structured data collection**: Consistent information gathering
- **Validation requirements**: Ensures quality submissions
- **Multiple issue types**: Bug reports, feature requests, questions
- **Pre-submission checklists**: Reduces duplicate and low-quality issues
### 4. Advanced Label Management
- **Hierarchical schema**: Priority, status, component, type, environment labels
- **Automatic synchronization**: Keeps labels consistent across repository
- **Migration support**: Handles deprecated label transitions
- **Audit capabilities**: Reports on label usage and health
### 5. Stale Issue Management
- **Automated cleanup**: Marks stale after 30 days, closes after 37 days
- **Smart detection**: Avoids marking active discussions as stale
- **Reactivation support**: Activity removes stale status automatically
### 6. PR Integration
- **Issue linking**: Automatically links PRs to referenced issues
- **Status updates**: Updates issue status during PR lifecycle
- **Resolution tracking**: Marks issues resolved when PRs merge
### 7. Metrics and Reporting
- **Daily metrics**: Tracks triage performance and health
- **Weekly reports**: Comprehensive analysis and recommendations
- **Health monitoring**: Identifies issues needing attention
- **Performance tracking**: Response times, resolution rates, quality metrics
### 8. Duplicate Detection
- **Smart matching**: Identifies potential duplicates based on title similarity
- **Automatic notification**: Alerts users to check existing issues
- **Manual override**: Maintainers can confirm or dismiss duplicate flags
## 🚦 Workflow Triggers
### Real-time Triggers
- Issue opened/edited/labeled/assigned
- Comments created/edited
- Pull requests opened/closed/merged
### Scheduled Triggers
- **Every 6 hours**: Core triage maintenance
- **Daily at 9 AM UTC**: Issue health checks
- **Daily at 8 AM UTC**: Metrics collection
- **Weekly on Mondays**: Detailed reporting
- **Weekly on Sundays**: Label synchronization
### Manual Triggers
- All workflows support manual dispatch
- Customizable parameters for different operations
- Emergency triage and cleanup operations
## 📊 Expected Performance Metrics
### Triage Efficiency
- **Target**: <24 hours for initial triage
- **Measurement**: Time from issue creation to first label assignment
- **Automation**: 80%+ of issues auto-labeled correctly
### Response Times
- **Target**: <48 hours for first maintainer response
- **Measurement**: Time from issue creation to first maintainer comment
- **Tracking**: Automated measurement and reporting
### Quality Improvements
- **Template adoption**: Expect >90% of issues using templates
- **Complete information**: Reduced requests for additional details
- **Reduced duplicates**: Better duplicate detection and prevention
### Issue Health
- **Stale rate**: Target <10% of open issues marked stale
- **Resolution rate**: Track monthly resolved vs. new issues
- **Backlog management**: Automated cleanup of inactive issues
## ⚙️ Configuration Management
### Environment Variables
- No additional environment variables required
- Uses GitHub's built-in GITHUB_TOKEN for authentication
- Repository settings control permissions
### Customization Points
- Assignee mappings in workflow scripts (currently set to @pab1it0)
- Stale issue timeouts (30 days stale, 7 days to close)
- Pattern matching keywords for auto-labeling
- Metric collection intervals and retention
## 🔧 Manual Override Capabilities
### Workflow Control
- All automated actions can be manually overridden
- Manual workflow dispatch with custom parameters
- Emergency stop capabilities for problematic automations
### Issue Management

- ✅ Modular job structure
- ✅ Clear separation of concerns
- ✅ Comprehensive logging
## 🏃♂️ Next Steps
### Immediate Actions
1. **Test workflows**: Create test issues to validate automation
2. **Monitor metrics**: Review initial triage performance
3. **Adjust patterns**: Fine-tune auto-labeling based on actual issues
4. **Train team**: Ensure maintainers understand the system
### Weekly Tasks
1. Review weekly triage reports
2. Check workflow execution logs
3. Adjust assignment rules if needed
4. Update documentation based on learnings
### Monthly Tasks
1. Audit label usage and clean deprecated labels
2. Review automation effectiveness metrics
3. Update workflow patterns based on issue trends
4. Plan system improvements and optimizations
## 🔍 Testing Recommendations
### Manual Testing
1. **Create test issues** with different types and priorities
2. **Test label synchronization** via manual workflow dispatch
3. **Verify assignment rules** by creating component-specific issues
4. **Test stale issue handling** with old test issues
5. **Validate metrics collection** after several days of operation
### Integration Testing
1. **PR workflow integration** - test issue linking and status updates
2. **Cross-workflow coordination** - ensure workflows don't conflict
3. **Performance under load** - test with multiple simultaneous issues
4. **Error handling** - test with malformed inputs and API failures
## ⚠️ Known Limitations
1. **Single maintainer setup**: Currently configured for one maintainer (@pab1it0)
2. **English-only pattern matching**: Auto-labeling works best with English content
3. **GitHub API rate limits**: May need adjustment for high-volume repositories
4. **Manual review required**: Some edge cases will still need human judgment
## 📈 Success Metrics
Track these metrics to measure automation success:
- **Triage time reduction**: Compare before/after automation
- **Response time consistency**: More predictable maintainer responses
- **Issue quality improvement**: Better structured, complete issue reports
- **Maintainer satisfaction**: Less manual triage work, focus on solutions
- **Contributor experience**: Faster feedback, clearer communication
---
**Status**: ✅ **READY FOR PRODUCTION**
All workflows are production-ready and can be safely deployed. The system will begin operating automatically once the files are committed to the main branch.

# Bug Triage Automation Documentation
This document describes the automated bug triage system implemented for the Prometheus MCP Server repository using GitHub Actions.
## Overview
The automated triage system helps maintain issue quality, improve response times, and ensure consistent handling of bug reports and feature requests through intelligent automation.
## System Components
### 1. 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
