Connect Cursor ​

  2. On Configure, copy the endpoint URL and bearer token

Configure tab with running badge, endpoint URL, and bearer token

  1. In Cursor MCP settings, add:
json
{
  "mcpServers": {
    "sumeru": {
      "url": "http://127.0.0.1:7341/mcp",
      "headers": {
        "Authorization": "Bearer <token>"
      }
    }
  }
}
  1. Reload MCP servers in Cursor
  2. Call list_mcps to confirm your configured upstreams appear

Stdio alternative ​

If you prefer stdio instead of HTTP:

json
{
  "mcpServers": {
    "sumeru": {
      "command": "sumeru",
      "args": ["mcp-stdio"]
    }
  }
}

Install the CLI with npm i -g sumeru-mcp first (or point SUMERU_BINARY at a local build).
