MCPizer exposes only 1 tool: 'sync-schema'. The tool has a basic description and a minimal input schema with one required parameter. However, the schema lacks critical documentation: the 'source' parameter has a generic description ('The source identifier or URL to sync schema from') with no examples, format constraints, or enumeration of valid values. The tool description does not explain WHEN to use it, WHAT happens after invocation, or what the tool returns. There is NO output schema documented, leaving LLMs unable to understand what data structure they'll receive. The tool performs a WRITE operation (synchronizes/registers tools) but the description does not explicitly state this is a mutating operation with side effects. Overall, the tool definition lacks the depth and precision needed for reliable LLM integration.

• Add an output schema documenting the structure returned by sync-schema. At minimum: {type: 'object', properties: {registered_tools: {type: 'array', items: {type: 'string'}}, errors: {type: 'array'}, success: {type: 'boolean'}}}.
• Enhance the 'source' parameter with constraints: enum of supported protocols (http, https, file, grpc) OR a regex pattern; examples of valid sources (e.g. 'https://api.example.com/openapi.yaml', 'file:///local/schema.proto'); and documentation of what schema formats are supported (OpenAPI 3.x, gRPC proto, GraphQL SDL).
• Clarify the tool description: 'Dynamically registers MCP tools by fetching and parsing an API schema from the provided source. This modifies the server's available tools. Idempotent: calling with the same source twice registers the same tools.' Include return value: 'Returns a list of registered tool names and any parsing errors.'
• Document error cases explicitly: 'Returns error if source is unreachable, schema is invalid, or tool names conflict with existing registrations. Use error message to diagnose (e.g., "Duplicate tool name: get_user, already registered").'
• Rename tool to 'register-tools-from-schema' or 'load-api-schema' to match the verb_noun pattern and clarify the action.
