WalkthroughLogging was simplified across MCP client and tool components to remove input/argument details from call and error logs, leaving only the tool name. Control flow, return values, and error handling behavior remain unchanged. Changes

- Ensure the code follows best practices and coding standards. - For Python code, follow
PEP 20 and
PEP 8 for style guidelines.- Check for security vulnerabilities and potential issues. - Python methods should use type hints for all parameters and return values.
Example:def my_function(param1: int, param2: str) -> bool: pass- For Python exception handling, ensure proper stack trace preservation:
- When re-raising exceptions: use bare
raisestatements to maintain the original stack trace,
and uselogger.error()(notlogger.exception()) to avoid duplicate stack trace output.- When catching and logging exceptions without re-raising: always use
logger.exception()
to capture the full stack trace information.Documentation Review Instructions - Verify that documentation and comments are clear and comprehensive. - Verify that the documentation doesn't contain any TODOs, FIXMEs or placeholder text like "lorem ipsum". - Verify that the documentation doesn't contain any offensive or outdated terms. - Verify that documentation and comments are free of spelling mistakes, ensure the documentation doesn't contain any
words listed in the

637-637: LGTM! Appropriate log simplification.Logging only the tool name at the info level is appropriate and removes potentially sensitive input data while maintaining essential context for debugging.

457-459: Duplicate logging resolved; consider usinglogger.exception()per guidelines.The duplicate logging issue has been successfully addressed by consolidating to a single log statement. The simplified logging (tool name only) aligns with the PR's cleanup objectives.
However, the coding guidelines specify: "use logger.exception() when catching without re-raising." While
logger.warning(..., exc_info=True)achieves similar stack trace logging, consider usinglogger.exception()for consistency with guidelines.Apply this diff if you prefer to align with the guidelines:
- logger.warning("Error calling tool %s", tool.name, exc_info=True) + logger.exception("Error calling tool %s", tool.name)Note: This changes the log level from WARNING to ERROR, which may be more appropriate for exceptions that interrupt tool execution.
