Quick start

Call Excalidraw MCP from your generated app's worker code via the OverSkill composio client. The toolkit slug below maps to Excalidraw MCP's public Composio identifier — your app references it by name and OverSkill handles the OAuth round-trip.

// In your generated app's worker handler:
const composio = composioClient(env);

const result = await composio.execute(
  "EXCALIDRAW_MCP_ACTION_NAME",
  { /* action parameters — see Actions section below */ }
);

return new Response(JSON.stringify(result), {
  headers: { "Content-Type": "application/json" }
});

Replace ACTION_NAME with one of the slugs listed in the Actions section below. The composio client handles auth + rate limits automatically — no API key is exposed to user code.

Setup

Excalidraw MCP requires no authentication — your app can call it directly. No "Connect" button is needed in the UI; the composio client wires it up automatically when you reference the toolkit ID.

Build with Excalidraw MCP

Open OverSkill, describe what you want to build, and reference Excalidraw MCP in your prompt — the AI will wire up the integration automatically.
