Cursor Hermoso list_errors

How to: Cursor Hermoso list_errors

client:Cursor transport:streamable-http tool:list_errors

Add Hermoso to Cursor

  1. 01

    Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "hermoso": {
      "url": "https://app.hermoso.ai/mcp?src=registry"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

    Ask for something list_errors does. Cursor lists the server's tools on connect and calls list_errors itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Hermoso's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs

Set these first

Hermoso will not start until these are set, so list_errors never becomes available.

  • HERMOSO_API_BASE

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
