Here's how to connect: ```typescript import { MultiServerMCPClient } from "@langchain/mcp-adapters"; const client = new MultiServerMCPClient({ mcpServers: { superset: { transport: "streamable_http", url: "http://your-superset-mcp-host:5008/mcp";, // Include auth header if JWT auth is enabled // headers: { // "Authorization": "Bearer YOUR_TOKEN" // } } } }); await client.initializeConnections(); const tools = await client.getTools(); ``` **Key details:** - The MCP server URL is `http://<host>:<port>/mcp` — the `/mcp` path is required [[2]](https://github.com/apache/superset/pull/40471). - Default port is `5008`, started via `superset mcp run --port 5008` [[1]](https://github.com/apache/superset/pull/33976). - The transport value for `@langchain/mcp-adapters` should be `"streamable_http"` (note: check the `@langchain/mcp-adapters` docs for the exact string your version expects — it may be `"streamable_http"` or `"streamable-http"`). - If JWT auth is enabled (`MCP_AUTH_ENABLED = True`), include an `Authorization: Bearer <token>` header in the config [[2]](https://github.com/apache/superset/pull/40471). The MCP server runs as a **separate process** on its own port (not through Superset's main web server on port 8088), so you connect to it directly [[1]](https://github.com/apache/superset/pull/33976). You can verify the server is reachable by opening `http://your-host:5008/mcp` in a browser — it displays a styled HTML hello page with setup instructions when running correctly [[2]](https://github.com/apache/superset/pull/40471). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Share context across your team and agents.
