From badea9a05a53c26673ca2e155ef51272aabcb720 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 17 Nov 2025 16:35:23 +0000 Subject: [PATCH 1/3] feat: Replace GitHub API with MCP Bridge integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete migration from direct GitHub API to MCP Bridge architecture. BREAKING CHANGES: - Requires MCP Bridge to be running - Removed VITE_GITHUB_TOKEN (now on backend only) - Removed githubService.ts (replaced with mcpService.ts) Changes: - Replace all GitHub API calls with MCP Bridge REST API - Create mcpService.ts for MCP Bridge communication - Update all hooks (useRepos, useContent) to use mcpService - Simplify configuration (only MCP Bridge URL needed) - Add MCP status indicator component - Add cache management functionality - Update environment variables - Remove GitHub token from frontend (security improvement) - Add Docker Compose orchestration - Update documentation with new architecture - Add integration test script New Architecture: React → MCP Bridge (FastAPI) → MCP Server (FastMCP) → GitHub API Security: GitHub token now secure on backend only Performance: 5-minute caching on bridge layer Features: All existing functionality maintained Files Changed: - .env (new MCP configuration) - .env.example (updated template) - .env.production (production config) - src/config/github.ts (simplified config) - src/utils/mcpService.ts (new MCP service) - src/utils/index.ts (service exports) - src/hooks/useRepos.tsx (use mcpService) - src/hooks/useContent.tsx (use mcpService) - src/components/ContentList.tsx (import from mcpService) - src/components/MCPStatusIndicator.tsx (new component) - src/components/ClearCacheButton.tsx (new component) - Dockerfile (production deployment) - docker-compose.yml (orchestration) - README.md (architecture docs) - package.json (new scripts) - scripts/test-mcp-integration.sh (test script) Removed: -

to correct location +- [ ] All dependencies installed (Bridge + Server) +- [ ] Environment variables configured +- [ ] Build command includes both components +- [ ] Test locally first: `cd mcp-bridge && python main.py` + +--- + +## 🧪 Local Testing with Full Stack + +**Test the full deployment setup locally:** + +```bash +# Navigate to bridge +cd /home/user/github-knowledge-vault/mcp-bridge + +# Ensure MCP Server is available +ls -la ../mcp-server/main.py # Should exist + +# Set environment variables +export GITHUB_TOKEN=your_token +export GITHUB_ORGANIZATION=SPerekrestova +export MCP_SERVER_PATH=../mcp-server/main.py + +# Start bridge (it will spawn MCP Server) +python main.py +``` + +**Check it works:** +```bash +# Health check +curl http://localhost:3001/health +# Should show: mcp_connected: true + +# Test repos +curl http://localhost:3001/api/repos +``` + +--- + +## 🐛 Troubleshooting + +### "MCP Server not found" +**Cause:** `MCP_SERVER_PATH` is incorrect + +**Solution:** +```bash +# Check file exists +ls -la $MCP_SERVER_PATH + +# Update path in .env +MCP_SERVER_PATH=../mcp-server/main.py # Adjust as needed +``` + +### "Module not found" errors +**Cause:** MCP Server dependencies not installed + +**Solution:** +```bash +# Install both sets of dependencies +pip install -r mcp-bridge/requirements.txt +pip install -r mcp-server/requirements.txt +``` + +### "mcp_connected: false" +**Cause:** MCP Server failed to start + +**Solution:** +Check bridge logs for error messages from MCP Server startup. + +--- + +## 💡 Recommended Approach + +**For free deployment to Render:** + +1. ✅ **Use Monorepo approach** (copy MCP Server into repo) +2. ✅ Update `MCP_SERVER_PATH=../mcp-server/main.py` +3. ✅ Deploy to Render as single web service +4. ✅ Both components run in same container + +**Repository structure:** +``` +github-knowledge-vault/ +├── src/ # Frontend +├── mcp-bridge/ # Bridge (FastAPI) +│ ├── main.py +│ ├── mcp_client.py +│ ├── requirements.txt +│ └── .env +├── mcp-server/ # Server (FastMCP) ← Add this +│ ├── main.py +│ ├── requirements.txt +│ └── ... +└── README.md +``` + +This way, Render deploys everything together in one service (free tier). + +--- + +## 🎉 Result + +Once deployed: +``` +User → Frontend (Vercel/Render) + ↓ HTTPS + MCP Bridge (Render) + ↓ stdio + MCP Server (same container) + ↓ API + GitHub API +``` + +All running on **free tier**, fully functional MCP architecture! 🚀 diff --git a/mcp-bridge/deploy.sh b/mcp-bridge/deploy.sh new file mode 100755 index 0000000..7101d55 --- /dev/null +++
