github-events-monitor 0.2.2

GitHub Events Monitor with FastAPI and MCP server

GitHub Events Monitor

A production-ready Python application that monitors GitHub Events API and provides real-time metrics via REST API and MCP (Model Context Protocol) server.

🎯 Features

• Real-time GitHub Events Monitoring: Streams WatchEvent, PullRequestEvent, and IssuesEvent
• REST API: FastAPI-based metrics and visualization endpoints
• MCP Server: Model Context Protocol integration for AI tools (Claude Desktop, Cursor)
• Production Ready: Comprehensive testing (35 tests), Docker support, proper packaging
• Scalable Architecture: SQLite with easy PostgreSQL migration path

🚀 Quick Start

Local Development

# Install dependencies
pip install -r requirements.txt

# Configure environment (copy .env.template to .env)
export GITHUB_TOKEN=your_github_token_here

# Run REST API server
python -m github_events_monitor.api

# Or run MCP server
python -m github_events_monitor.mcp_server

Docker Deployment

# Using Docker Compose (recommended)
docker-compose up -d

# Or with Docker directly
docker run -d \
  --name github-events-monitor \
  -p 8000:8000 \
  -e GITHUB_TOKEN=your_token \
  sparesparrow/github-events-monitor:latest

📊 API Endpoints

Core Metrics (Assignment Requirements)

• GET /metrics/event-counts?offset_minutes=10 - Event counts by type with time offset
• GET /metrics/pr-interval?repo=owner/repo - Average time between pull requests

Additional Features

• GET /metrics/repository-activity?repo=owner/repo&hours=24 - Repository activity summary
• GET /metrics/trending?hours=24&limit=10 - Trending repositories
• GET /visualization/trending-chart - Chart visualization (bonus)
• GET /health - Health check endpoint

Documentation

• Interactive API docs available at http://localhost:8000/docs
• OpenAPI specification at http://localhost:8000/openapi.json

🎯 Use Cases

1. Real-time Repository Health Check

Monitor short-term activity and overall health when you need a quick pulse (on-call, triage, stakeholder reviews).

# Get event volume by type over last 60 minutes
curl "http://localhost:8000/metrics/event-counts?offset_minutes=60"

# Check repository activity for last 24 hours
curl "http://localhost:8000/metrics/repository-activity?repo=owner/repo&hours=24"

2. Release Readiness Assessment

Assess if a codebase is trending toward a stable release by looking at PR cadence and activity distribution.

# Get average time between pull requests
curl "http://localhost:8000/metrics/pr-interval?repo=owner/repo"

3. Development Velocity Tracking

Track how frequently contributors open pull requests as a proxy for development velocity.

4. Incident Detection

Detect sudden spikes in Issues or PRs that may indicate incidents or regressions.

5. Community Interest Monitoring

Use WatchEvent counts as an interest/awareness signal for marketing or devrel purposes.

🏗️ Architecture

GitHub API → [Background Collector] → [SQLite DB] → [Metrics Engine] → [REST API / MCP Server]

• Background Collector: Async polling with rate limiting and ETag caching
• SQLite Database: Local storage with optimized indices
• REST API: FastAPI endpoints for metrics and visualizations
• MCP Server: AI tool integration via Model Context Protocol

🧪 Testing

# Run all tests
pytest

# Run specific test categories
pytest tests/unit          # Unit tests
pytest tests/integration   # Integration tests

# With coverage
pytest --cov=src/github_events_monitor

Test Results: 35/35 tests passing (100% success rate)
