Let agents operate the same contract humans use.

One-click install

The hosted Streamable HTTP endpoint is the product. Cursor and VS Code Copilot open a browser for signup and scope consent. There is no API key in the MCP config.

Add to Cursor Add to VS Code

In Cursor you can also run:

/add-plugin marmunk

Manual MCP entry:

{
  "mcpServers": {
    "marmunk": {
      "url": "https://api.marmunk.com/mcp"
    }
  }
}

Signup is the OAuth loop. Connect opens Google sign-in, then Approve. First-time Approve creates a test-only account, names the organization from your email, and accepts Terms. Agents cannot create accounts through a tool.

Hosted connection

https://api.marmunk.com/mcp

Use this URL directly in an OAuth-capable MCP client. Marmunk opens a browser for Google sign-in and explicit scope consent. First-time Approve creates the test-only account. Read access is selected by default; management and sending require separate approval. Production sending stays off; 10 emails a day until you add a card.

Remote send debugging

Tool: marmunk_email_trace
Input: { "reference_id": "msg_01example" }

// A req_* reference traces one API attempt.
// A msg_* reference traces the durable send lifecycle.

Same safety boundaries

MCP calls carry a channel marker for audit and debugging, but authentication, tenant isolation, idempotency, policy, suppression, quota, and approval behave exactly like direct REST calls.
