How do I connect the Excalidraw MCP server to Claude?

The registry lists a hosted endpoint at https://draw.404040.net/mcp. Check the publisher's authentication and client requirements, then add the endpoint as a custom connector in Claude and complete any sign-in it requires.

In Claude Code, run:

claude mcp add --transport http excalidraw https://draw.404040.net/mcp

Does the Excalidraw MCP server work with ChatGPT?

A hosted endpoint is available at https://draw.404040.net/mcp. ChatGPT needs a compatible remote transport and authentication flow, and your account or workspace must allow custom MCP connections. Confirm those requirements with the publisher before connecting.

How do I add it to Cursor?

Start with this remote endpoint in .cursor/mcp.json in your project, or ~/.cursor/mcp.json for every project. Add any authentication fields required by the publisher:

{
  "mcpServers": {
    "excalidraw": {
      "url": "https://draw.404040.net/mcp"
    }
  }
}
