Mermaid Chart MCP integration

Quick start

Call Mermaid Chart MCP from your generated app's worker code via the OverSkill composio client. The toolkit slug below maps to Mermaid Chart 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(
  "MERMAID_CHART_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

Mermaid Chart 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.
