Tembo MCP Server

Instructions

Implementation Reference

• src/tools.ts:318-329 (handler)

  Handler function that implements the 'get_all_instances' tool logic by fetching all instances for the given organization ID using temboClient.getAll and returning the result as text content.

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

• src/tools.ts:59-72 (schema)

  Input schema definition for the 'get_all_instances' tool, part of the TOOLS array, specifying the required 'org_id' parameter.

  {
  	name: "get_all_instances" as const,
  	description: "Get all Tembo instances in an organization",
  	inputSchema: {
  		type: "object",
  		properties: {
  			org_id: {
  				type: "string",
  				description: "Organization id for the request",
  			},
  		},
  		required: ["org_id"],
  	},
  },

• src/index.ts:32-34 (registration)

  Registration of tool list handler, which returns the TOOLS array containing the schema for 'get_all_instances'.

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

• src/index.ts:36-59 (registration)

  Registration of the generic tool call handler that dispatches to TOOL_HANDLERS[toolName], enabling execution of 'get_all_instances'.

  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,
  			};
  		}
  	},
  );
