Issues Found and Resolved

Issue 1: Incorrect API Endpoints ✅ FIXED

  • Problem: Geocoding and historical APIs returned 404
  • Cause: Wrong domain names
  • Fix: Updated to correct subdomains
    • Geocoding: geocoding-api.open-meteo.com
    • Historical: archive-api.open-meteo.com

Issue 2: HTTP Mode by Default ✅ FIXED

  • Problem: Server started in HTTP mode, not STDIO
  • Cause: chuk-mcp-server defaults to HTTP
  • Fix: Explicitly set transport="stdio" as default

Issue 3: Verbose Logging in STDIO Mode ✅ FIXED

  • Problem: INFO logs polluting JSON-RPC stream
  • Cause: Default logging level too verbose
  • Fix: Set logging to ERROR level in STDIO mode, use stderr

Issue 4: Python Version Mismatch ✅ FIXED

  • Problem: pyproject.toml said >=3.10, but chuk-mcp-server requires >=3.11
  • Cause: Incorrect version specification
  • Fix: Updated to requires-python = ">=3.11"
