Excalidraw+ MCP

Excalidraw+ MCP lets AI clients access your Excalidraw Plus workspace through the Model Context Protocol (MCP).

If you are looking for the open source MCP server, see excalidraw/excalidraw-mcp. We may merge the Excalidraw+ and open source MCP efforts more closely over time.

Endpoint

https://api.excalidraw.com/api/v1/mcp

Quick install

To connect an MCP client, use the same setup described in Getting Started:

1. Create an Excalidraw Plus API key.
2. Point your MCP client at the Excalidraw+ MCP endpoint.
3. Send the API key as a bearer token.

Example config:

{
  "mcpServers": {
    "excalidraw": {
      "url": "https://api.excalidraw.com/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer <API_KEY>"
      }
    }
  }
}

How it works

• Transport: Streamable HTTP
• Auth: Authorization: Bearer <API_KEY>
• Mode: Stateless (no long-lived server session)
• Permissions: tools are filtered by the same API key permissions as the API

Alpha notes

• MCP behavior may change as the underlying API evolves
• Tool names, schemas, and output formats may change during alpha
• If you need the most stable integration path today, use the REST API directly
