Cursor

Add rho to ~/.cursor/mcp.json to have it in every project, or to .cursor/mcp.json in one project:

{
  "mcpServers": {
    "rho": {
      "url": "https://api.rho.store/mcp"
    }
  }
}

Then open Cursor Settings → MCP. rho is listed and asks you to sign in: your browser opens rho, where you sign in, choose Read and write or Read only, and allow it.
