Single tool with severely deficient schema and naming. Tool name '_________available_mcp_services_for_easy_copy_________' violates verb_noun convention and is unmaintainable. Input schema is empty object {} with no parameter definitions. Description is generic (34 chars, below 50-char minimum for clarity). No output schema documented. Tool conflates two concerns: listing services AND providing usage instructions. No error handling guidance. No parameter validation. Fails 7 of 8 critical checks in Definition Quality rubric.

• Rename tool to 'list_mcp_services' (verb_noun convention, 18 chars, matches baseline average). Removes underscore padding and clarifies action.
• Expand description to 80-150 chars: 'List all MCP services configured in Claude Desktop. Returns service names for use in prompts. Call this to discover available integrations before requesting agent actions.'
• Define explicit input schema: {"type": "object", "properties": {}, "required": [], "additionalProperties": false}. Even empty schemas must be formally declared.
• Document output schema: {"type": "object", "properties": {"services": {"type": "array", "items": {"type": "string"}}, "count": {"type": "integer"}}, "required": ["services", "count"]}. Return structured JSON, not formatted text.
• Split into two tools: (1) 'list_mcp_services' returns {services: [string], count: int}; (2) 'get_mcp_service_guide' returns usage instructions. Follows single-responsibility principle.
