Cline tldraw _exec_callback

How to: Cline tldraw _exec_callback

client:Cline transport:streamable-http tool:_exec_callback

Add tldraw to Cline

  1. 01

    Open ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "tldraw": {
      "url": "https://tldraw-mcp-app.tldraw.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Cline.

  2. 03

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

  3. 04

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

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.
