Critical gaps across naming, descriptions, and schemas. 33 tools with minimal documentation. Most descriptions are generic (10-30 chars), far below the 194-char baseline. Parameter schemas are sparse, many tools accept generic 'object' types with no field documentation. No output schemas documented. Error handling absent. Tool names lack clarity (e.g., 'call' is dangerously vague). No evidence of idempotency, pagination, or composition patterns. This server exposes raw API complexity rather than abstracting it for agent use.

• Rename 'call' to something specific like 'invoke_comfy_tool' and document exactly which ComfyUI MCP tools it can invoke. Add an enum of valid tool names or a discovery mechanism. This prevents accidental misuse and enables audit trails.
• Expand all descriptions to 100-200 characters. For each tool, answer: What does it do? When should the LLM call it? What does it return? Example: 'save_config' → 'Save configuration settings to persistent storage. Call this after modifying server URLs, authentication, or workflow paths. Returns success status and updated config timestamp.'
• Replace generic 'object' parameter schemas with explicit field definitions. Example: save_config's 'config' param should specify: {'type': 'object', 'properties': {'servers': {'type': 'array'}, 'auth_token': {'type': 'string'}, ...}, 'required': ['servers']}. Use JSON Schema $ref for reusable models.
• Document output schemas for all tools. Example: list_workflows should return {'type': 'object', 'properties': {'workflows': {'type': 'array', 'items': {'type': 'object', 'properties': {'workflow_id': {'type': 'string'}, 'name': {'type': 'string'}, ...}}}, 'total': {'type': 'integer'}}.
• Add error handling and recovery guidance. For destructive tools, implement a confirmation pattern: 'delete_workflow' should return 'Workflow marked for deletion. Call confirm_delete(workflow_id) to finalize.' For failures, return actionable errors: 'Server offline. Check server_status(server_id) or test_connection(url) to diagnose.'
