Implementation Reference
- server.ts:240-288 (registration)Registration of the 'get_type_info' MCP tool, including name, description, input schema, and inline handler function.server.tool( "get_type_info", "Get type information for a Square API method. You must call this before calling the make_api_request tool.", { service: z.string().describe("The Square API service category (e.g., 'catalog', 'payments')"), method: z.string().describe("The API method to call (e.g., 'list', 'create')") }, async (params) => { try { const { service, method } = params; const serviceName = service.charAt(0).toUpperCase() + service.slice(1); const methods = serviceMethodsMap[serviceName]; if (!methods) { throw new Error(`Invalid service: ${service}. Available services: ${JSON.stringify(Object.keys(serviceMethodsMap), null, 2)}`); } if (!methods[method]) { throw new Error(`Invalid method ${method} for service ${service}. Available methods: ${JSON.stringify(Object.keys(methods), null, 2)}`); } const methodInfo = methods[method]; const requestTypeName = methodInfo.requestType; const typeInfo = typeMap[requestTypeName]; if (!typeInfo) { throw new Error(`Type information not found for ${requestTypeName}`); } return { content: [{ type: "text", text: JSON.stringify(typeInfo, null, 2) }] }; } catch (err: any) { return { content: [{ type: "text", text: JSON.stringify({ error: err.message, details: err.errors || err.stack }, null, 2) }], isError: true }; } } );
- server.ts:247-287 (handler)Executes the logic for 'get_type_info': capitalizes service name, retrieves method info from serviceMethodsMap, fetches type info from typeMap using requestType, and returns as JSON text content.async (params) => { try { const { service, method } = params; const serviceName = service.charAt(0).toUpperCase() + service.slice(1); const methods = serviceMethodsMap[serviceName]; if (!methods) { throw new Error(`Invalid service: ${service}. Available services: ${JSON.stringify(Object.keys(serviceMethodsMap), null, 2)}`); } if (!methods[method]) { throw new Error(`Invalid method ${method} for service ${service}. Available methods: ${JSON.stringify(Object.keys(methods), null, 2)}`); } const methodInfo = methods[method]; const requestTypeName = methodInfo.requestType; const typeInfo = typeMap[requestTypeName]; if (!typeInfo) { throw new Error(`Type information not found for ${requestTypeName}`); } return { content: [{ type: "text", text: JSON.stringify(typeInfo, null, 2) }] }; } catch (err: any) { return { content: [{ type: "text", text: JSON.stringify({ error: err.message, details: err.errors || err.stack }, null, 2) }], isError: true }; } }
- server.ts:243-246 (schema)Zod input schema for the 'get_type_info' tool, requiring 'service' and 'method' strings.{ service: z.string().describe("The Square API service category (e.g., 'catalog', 'payments')"), method: z.string().describe("The API method to call (e.g., 'list', 'create')") },
