Debug incoming tool calls¶

Add --debug-tool-calls to your existing server command to print redacted JSON diagnostics in the terminal where the server runs:

uv run --frozen etrade-mcp serve --debug-tool-calls

This is off by default. You can also set ETRADE_MCP_DEBUG_TOOL_CALLS=true; --no-debug-tool-calls overrides that setting. Both HTTP and stdio write one JSON line per event to stderr, keeping stdout reserved for MCP traffic. HTTP authentication and other startup settings still apply.

Each tool_call.received event includes a generated call_id, the tool name, argument types, and a bounded argument preview. A matching tool_call.completed event reports success/error status and safe error codes and validation paths. Account, order, transaction, alert, and client-order identifiers are masked. Credentials and authentication fields are withheld; unknown field names and values are omitted, with only their count recorded. Broker response bodies and error messages are never included. Selected trading inputs, including symbols, prices, quantities, and order settings, are intentionally visible while enabled.
