This server has critical definition failures. The single tool 'execute_skill_action' has no visible input schema in the source code, only a description string. The mcp_server.py file contains no tool registration, no parameter definitions, and no output schema documentation. The tool description is vague (28 chars, below the 34-char p10 baseline) and does not explain WHAT the tool does, WHEN to use it, or what it returns. The client.py and example_usage.py files show example usage but are not part of the MCP server definition itself. No input validation, error handling, or security controls are evident. This is a stub implementation, not a production-ready MCP server.

• Add explicit JSON Schema for execute_skill_action input parameters. Define required fields (e.g., audio_command_transcript: string), optional fields (available_integrations: array of strings), and constraints (e.g., transcript length limits).
• Expand tool description to 100 - 200 characters. Example: 'Converts a voice command transcript into a structured action with parameters. Accepts optional integration list to filter available actions. Returns dispatched_action, payload_parameters, and execution_status.'
• Document the output schema with typed fields: dispatched_action (enum of valid actions), payload_parameters (object with action-specific keys), execution_status (enum: DISPATCHED_200_OK, INVALID_INTENT, etc.).
• Implement proper MCP JSONRPC message handling in mcp_server.py. Use a library like mcp (https://github.com/modelcontextprotocol/python-sdk) or implement the protocol loop to receive tool calls and return structured responses.
• Add input validation and error responses. Return actionable errors like 'Invalid transcript: must be non-empty string under 1000 chars' instead of silent failures.
