  </Accordion>

  <Accordion title="Tools not appearing">
    Restart your MCP client after updating the config file. Some clients require a full restart to detect new MCP servers.

    ```json theme={null}
    {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.dataforb2b.ai/mcp"]
    }
