The plan's route signatures used query parameters, which worked for direct HTTP callers and unit tests, but fastapi-mcp's HTTP transport passes tools/call arguments as a JSON body. dict-typed parameters like spark_conf arrived as a string and the route returned 422. Refactor each route to take a single Pydantic body model (saved in spark_executor/tools/requests.py). Underlying tool functions unchanged. Integration tests in tests/integration/test_mcp_routes.py now exercise the full body-based roundtrip (save_connection with spark_conf, prepare → list → get, list_connections with empty body).
