Tembo MCP Server

Instructions

Implementation Reference

• src/tools.ts:276-287 (handler)

  The asynchronous handler function for the 'get_app' tool. It extracts the 'type' parameter from the request, calls temboClient.getApp with it, and returns the response data or error as JSON-formatted text content.

  get_app: async (request) => {
  	const { type } = request.params.arguments as { type: string };
  	const response = await temboClient.getApp({ path: { type } });
  	return {
  		content: [
  			{
  				type: "text",
  				text: JSON.stringify(response.data ?? response.error, null, 2),
  			},
  		],
  	};
  },

• src/tools.ts:22-35 (schema)

  The tool registration object defining the name, description, and input schema for 'get_app', which requires a 'type' string parameter.

  {
  	name: "get_app" as const,
  	description: "Get the attributes of a single App",
  	inputSchema: {
  		type: "object",
  		properties: {
  			type: {
  				type: "string",
  				description: "The app type to get details for",
  			},
  		},
  		required: ["type"],
  	},
  },

• src/index.ts:32-34 (registration)

  Registers the list tools handler, which returns the TOOLS array including the 'get_app' tool definition.

  server.setRequestHandler(ListToolsRequestSchema, () => {
  	return { tools: TOOLS };
  });

• src/index.ts:36-59 (registration)

  Registers the call tool handler, which dispatches to the specific TOOL_HANDLERS[toolName] including 'get_app' if allowed.

  server.setRequestHandler(
  	CallToolRequestSchema,
  	async (request): Promise<z.infer<typeof CallToolResultSchema>> => {
  		const toolName = request.params.name;
  
  		try {
  			if (isAllowedTool(toolName)) {
  				return await TOOL_HANDLERS[toolName](request);
  			}
  
  			throw new Error(`Unknown tool: ${toolName}`);
  		} catch (error) {
  			return {
  				content: [
  					{
  						type: "text",
  						text: `Error: ${error instanceof Error ? error.message : String(error)}`,
  					},
  				],
  				isError: true,
  			};
  		}
  	},
  );
