Implementation Reference

• src/commit_helper_mcp/server/message_tools.py:112-147 (handler)

  The core handler function decorated with @mcp.tool() that implements the 'create_commit_message' tool logic. It takes a dictionary of answers, generates a commit message using the service, validates it, and returns the result.

  @mcp.tool()
  @handle_errors(log_errors=True)
