Fabits MCP Server

# Portfolio API Integration Test This script tests the `fabits_get_portfolio` function with real API calls to validate the bearer token authentication and API integration. ## Prerequisites 1. **Build the project:** ```bash npm run build ``` 2. **Authenticate first** (if not already): You must be logged in with valid tokens. Use the MCP server: ```bash # Start MCP server in another terminal node build/server.js # Then authenticate: # - fabits_request_otp <phone> # - fabits_verify_otp <otp> ``` ## Running the Test ```bash node scripts/test-portfolio.js ``` ## What It Tests ✅ Token loading from auth file ✅ Bearer token authentication ✅ Real API call to `/mutualfundservice/api/mutualFund/holdings` ✅ Response parsing and data processing ✅ Separation of Fabits vs External holdings ✅ Portfolio totals calculation ✅ Error handling ## Expected Output ``` 🧪 Testing Portfolio API Integration 📂 Loading authentication tokens... ✅ Tokens loaded successfully!

The portfolio function successfully: ✓ Authenticated with bearer token ✓ Made real API call to holdings endpoint ✓ Parsed and processed the response ✓ Returned formatted portfolio data ``` ## Troubleshooting ### ❌ Error: No authentication tokens found **Solution:** You need to login first via the MCP server ### ❌ Error: Failed to fetch portfolio: 401 Unauthorized **Solution:** Your token has expired. The function should auto-refresh, but if it fails, login again ### ❌ Error: ECONNREFUSED **Solution:** Check your internet connection and that the API is accessible ## Debugging The script outputs detailed logs to stderr including: - Full request details - Response headers and preview - Data structure analysis - Parsing steps - Error stack traces These logs help diagnose any issues with the API integration. ## What This Validates This test proves that: 1. ✅ Bearer token is properly attached to requests 2. ✅ API endpoint is correct and accessible 3. ✅ Response format is as expected 4. ✅ Data parsing logic works with real data 5. ✅ Error handling catches edge cases 6. ✅ Token auto-refresh works (if tested with expired token) ## Next Steps After this test passes, you can use the portfolio tool via: - MCP server tool calls - n8n workflows - Any MCP client
