Invocation via SDK

Install dependencies:

npm i @cloudbase/mcp @modelcontextprotocol/sdk

Go to Cloud Development Platform to get API KEY.

Connect to the MCP Server based on its Transport type:

Streamable HTTP

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";

const transport = new StreamableHTTPClientTransport(
  // Replace "your-env-id" in the link with your CloudBase environment id
  // Replace "your-service-name" in the link with your Cloud Hosting service name
  new URL(
    "https://your-env-id.api.tcloudbasegateway.com/v1/cloudrun/your-service-name/messages"
  ),
  {
    requestInit: {
      headers: {
        // Replace "your-api-key" with your actual API KEY
        Authorization: `Bearer your-api-key`,
      },
    },
  }
);

const client = new Client(
  {
    name: "your-mcp-name",
    version: "1.0.0",
  },
  {
    capabilities: {
      tools: {},
    },
  }
);

await client.connect(transport);

SSE

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { SSEClientTransport } from "@modelcontextprotocol/sdk/client/sse.js";

const transport = new SSEClientTransport(
  // Replace "your-env-id" in the link with your CloudBase environment id
  // Replace "your-service-name" in the link with your Cloud Hosting service name
  new URL(
    "https://your-env-id.api.tcloudbasegateway.com/v1/cloudrun/your-service-name/messages"
  ),
  {
    requestInit: {
      headers: {
        // Replace "your-api-key" with your actual API KEY
        Authorization: `Bearer your-api-key`,
      }
    },
    eventSourceInit: {
      fetch: (url, init) => {
        return fetch(url, {
          ...(init || {}),
          headers: {
            ...(init?.headers || {}),
            // Replace "your-api-key" with your actual API KEY
            Authorization: `Bearer your-api-key`,
          }
        })
      }
    }
  }
);

const client = new Client(
  {
    name: "your-mcp-name",
    version: "1.0.0",
  },
  {
    capabilities: {
      tools: {},
    },
  }
);

await client.connect(transport);

POST

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { PostClientTransport } from "@cloudbase/mcp/transport/client/post";

const transport = new PostClientTransport(
  // Replace "your-env-id" in the link with your CloudBase environment id
  // Replace "your-service-name" in the link with your Cloud Hosting service name
  new URL(
    "https://your-env-id.api.tcloudbasegateway.com/v1/cloudrun/your-service-name/messages"
  ),
  {
    requestInit: {
      headers: {
        // Replace "your-api-key" with your actual API KEY
        Authorization: `Bearer your-api-key`,
      },
    },
  }
);

const client = new Client(
  {
    name: "your-mcp-name",
    version: "1.0.0",
  },
  {
    capabilities: {
      tools: {},
    },
  }
);

await client.connect(transport);

Retrieve the tool list from MCP Server:

const prompts = await client.listTools();

Initiate tool invocation:

const result = await client.callTool({
  name: "example-tool",
  arguments: {
    arg1: "value",
  },
});
