Cursor AI Form API (fill) submit_fill

How to: Cursor AI Form API (fill) submit_fill

client:Cursor transport:streamable-http tool:submit_fill

Add AI Form API (fill) to Cursor

  1. 01

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

{
  "mcpServers": {
    "aiformapi-fill": {
      "url": "https://aiformapi.com/mcp/fill"
    }
  }
}
  1. 02

    Save the file and restart Cursor.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that AI Form API (fill)'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

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 November 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.
