Three steps to your first send

1. Get your key

Generate a tr_live_ API key at truncus.co/dashboard/settings/api-keys. Free tier — no credit card.

2. Add the server

Paste the config into your editor once. The server is @vanmoose/mcp-server on npm.

3. Just ask

Tell your agent to send an email. It calls Truncus, gets delivery proof back, and reports what happened.

Add it to your editor

Works in any MCP client. Generate a key at truncus.co/dashboard/settings/api-keys and drop it into the config below.
