8 | A [Model Context Protocol][mcp] (MCP) server for Prometheus.
9 |
10 | 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.
11 |
12 | [mcp]: https://modelcontextprotocol.io
13 |
14 | ## Features
15 |
16 | - [x] Execute PromQL queries against Prometheus
17 | - [x] Discover and explore metrics
18 | - [x] List available metrics
19 | - [x] Get metadata for specific metrics
20 | - [x] View instant query results
21 | - [x] View range query results with different step intervals
22 | - [x] Authentication support
23 | - [x] Basic auth from environment variables
24 | - [x] Bearer token auth from environment variables
25 | - [x] Docker containerization support
26 |
27 | - [x] Provide interactive tools for AI assistants
28 |
29 | The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.
30 | 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.

106 |
107 | ## Coding Standards
108 |
109 | Please follow these guidelines when writing code:
110 |
111 | ### Python Style Guide
112 |
113 | - Follow [PEP 8](https://peps.python.org/pep-0008/) style guide
114 | - Use meaningful variable and function names
115 | - Write docstrings for all public modules, functions, classes, and methods
116 | - Keep functions focused and single-purpose
117 | - Maximum line length: 100 characters (when practical)
118 |
119 | ### Code Organization
120 |
121 | - Place new functionality in appropriate modules
122 | - Keep related code together
123 | - Avoid circular dependencies
124 | - Use type hints where appropriate
125 |
126 | ### Documentation
127 |
128 | - Update the README.md if you change functionality
129 | - Add docstrings to new functions and classes
130 | - Comment complex logic or non-obvious implementations
131 | - Keep comments up-to-date with code changes
132 |
133 | ### Commit Messages
134 |
135 | Write clear, concise commit messages:
136 |
137 | - Use the present tense ("Add feature" not "Added feature")
138 | - Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
139 | - Limit the first line to 72 characters or less
140 | - Reference issues and pull requests when relevant
141 | - For example:
142 | ```
143 | feat: add support for custom headers in Prometheus requests
144 |
145 | - Adds PROMETHEUS_CUSTOM_HEADERS environment variable
146 | - Updates documentation with usage examples
147 | - Includes tests for header validation
148 |
149 | Fixes #106
150 | ```
151 |
152 | ## Testing Guidelines
153 |
154 | All contributions must include appropriate tests. We use `pytest` for testing.
155 |
156 | ### Running Tests
157 |
158 | ```bash
159 | # Run all tests
160 | pytest
161 |
162 | # Run with coverage report
163 | pytest --cov=src --cov-report=term-missing
164 |
165 | # Run specific test file
166 | pytest tests/test_specific.py
167 |
168 | # Run tests matching a pattern
169 | pytest -k "test_pattern"
170 | ```
171 |
172 | ### Test Requirements
173 |
174 | - **Write tests for new features** - All new functionality must have corresponding tests
175 | - **Maintain code coverage** - Aim for 80%+ code coverage (enforced by CI)
176 | - **Test edge cases** - Consider error conditions and boundary cases
177 | - **Use meaningful test names** - Test names should describe what they're testing
178 | - **Keep tests isolated** - Tests should not depend on each other
179 | - **Mock external dependencies** - Use `pytest-mock` for mocking Prometheus API calls
180 |
181 | ### Test Structure
182 |
183 | ```python
184 | def test_feature_description():
185 | """Test that feature does what it should."""
186 | # Arrange - Set up test conditions
187 | # Act - Execute the functionality being tested
188 | # Assert - Verify the results
189 | ```
190 |

200 | - `create-missing`: Only create missing labels
201 | - `audit`: Report on unused/deprecated labels
202 | - `cleanup`: Migrate deprecated labels on issues
203 |
204 | #### Issue Management Workflow
205 | - `health-check`: Run issue health analysis
206 | - `close-stale`: Process stale issue closure
207 | - `update-metrics`: Refresh metric calculations
208 | - `sync-labels`: Synchronize label schema
209 |
210 | #### Metrics Workflow
211 | - `daily`/`weekly`/`monthly`: Generate period reports
212 | - `custom`: Custom date range analysis
213 |
214 | ## Best Practices
215 |
216 | ### For Maintainers
217 |
218 | 1. **Regular Monitoring**:
219 | - Check weekly triage reports
220 | - Review health check notifications
221 | - Act on escalated high-priority issues
222 |
223 | 2. **Label Hygiene**:
224 | - Use consistent labeling patterns
225 | - Run label sync weekly
226 | - Audit unused labels monthly
227 |
228 | 3. **Response Times**:
229 | - Aim to respond to new issues within 48 hours
230 | - Prioritize critical and high-priority issues
231 | - Use template responses for common questions
232 |
233 | ### For Contributors
234 |
235 | 1. **Issue Creation**:
236 | - Use appropriate issue templates
237 | - Provide complete information requested in templates
238 | - Check for existing similar issues before creating new ones
239 |
240 | 2. **Issue Updates**:
241 | - Respond promptly to requests for additional information
242 | - Update issues when circumstances change
243 | - Close issues when resolved independently
244 |
245 | ## Troubleshooting
246 |
247 | ### Common Issues
248 |
249 | 1. **Labels Not Applied**: Check if issue content matches pattern keywords
250 | 2. **Assignment Not Working**: Verify component labels are correctly applied
251 | 3. **Stale Issues**: Issues marked stale can be reactivated by adding comments
252 | 4. **Duplicate Detection**: May flag similar but distinct issues - review carefully
253 |
254 | ### Manual Overrides
255 |
256 | All automated actions can be manually overridden:
257 | - Add/remove labels manually
258 | - Change assignments
259 | - Remove stale status by commenting
260 | - Close/reopen issues as needed
261 |
262 | ## Configuration
263 |
264 | ### Environment Variables
265 | No additional environment variables required - system uses GitHub tokens automatically.
266 |
267 | ### Permissions
268 | Workflows require:
269 | - `issues: write` - For label and assignment management
270 | - `contents: read` - For repository access
271 | - `pull-requests: read` - For PR integration
272 |
273 | ## Monitoring and Maintenance
274 |
275 | ### Regular Tasks
276 | 1. **Weekly**: Review triage reports and health metrics
277 | 2. **Monthly**: Audit label usage and clean up deprecated labels
278 | 3. **Quarterly**: Review automation rules and adjust based on repository needs
279 |
280 | ### Performance Metrics
281 | - Triage time: Target <24 hours for initial triage
282 | - Response time: Target <48 hours for first maintainer response
283 | - Resolution time: Varies by issue complexity and priority
284 | - Stale rate: Target <10% of open issues marked as stale
285 |
286 | ## Future Enhancements
287 |
288 | Potential improvements to consider:
289 | 1. **AI-Powered Classification**: Use GitHub Copilot or similar for smarter issue categorization
290 | 2. **Integration with External Tools**: Connect to project management tools or monitoring systems
291 | 3. **Advanced Duplicate Detection**: Implement semantic similarity matching
292 | 4. **Automated Testing**: Trigger relevant tests based on issue components
293 | 5. **Community Health Metrics**: Track contributor engagement and satisfaction
294 |
