🔗 MCP Protocol Integration

This server supports the full MCP JSON-RPC protocol.

Example tool call:

curl -X POST https://mcp-weathertrax.jaredco.com/mcp \  -H "Content-Type: application/json" \  -H "Accept: application/json, text/event-stream" \  -d '{    "jsonrpc":"2.0",    "id":1,    "method":"tools/call",    "params":{      "name":"weatherTool",      "arguments":{        "location":"London",        "query_type":"current"      }    }  }'

🧪 Testing

Run locally in one terminal:

npm installnpm start

In another terminal, run the protocol tests:

npm test

Release smoke suite:

npm run test:full

npm run test:full currently runs the same supported end-to-end smoke suite. The old pre-Streamable-HTTP regression harness remains available as npm run test:legacy; it is retained for reference and is not a release gate.

Deployment configuration

Set these server-side environment variables; never commit them:

The service exposes aggregate, non-identifying operational counters at /metrics. Do not place this endpoint behind a public dashboard without adding appropriate access control.

🔒 Privacy

Privacy policy available at:

Key points:

• Aggregate operational metrics only; locations and raw provider responses are not logged
• Short-lived in-memory caching reduces duplicate provider requests
• No cookies or tracking
• HTTPS enforced
