Your whole email API, as agent tools.

The Drin MCP server exposes around 54 typed tools — everything the REST API can do, handed to an agent so it can send, receive, template and track mail through the Model Context Protocol.

// how to connect[01/03]

Works with any MCP client.

1
Get an API key
Create a scoped key in the dashboard. The MCP server authenticates as that key, so the agent inherits exactly its permissions.
2
Add the server to your client
Register Drin in your client's mcpServers config — Claude, Cursor, Codex and other MCP hosts all read the same shape.
3
Let the agent send
Restart the client and the 54 tools appear. Ask the agent to send a test email or triage the inbox — it calls Drin directly.

Not a send button — the whole API.

Send & batch

Compose and send a single message or up to 100 at once, with attachments, scheduling and idempotency keys.

send_email · send_batch

Domains & keys

Add a domain, fetch its DNS records, trigger verification, and mint or revoke scoped API keys — without leaving the agent.

domains · api_keys

Templates & webhooks

Create and version reusable templates, send by id, and register signed webhook endpoints for delivery events.

templates · webhooks

Inbox & reply

List threads, read a message and its history, and reply in-thread from the agent's own address. Receiving, not just sending.

list · get · reply

Contacts

Read and manage the per-sender address book, plus unsubscribe and suppression state, so the agent respects opt-outs.

contacts · suppression

Metrics

Pull volume, delivery, bounce and complaint rates and the raw event ledger — the agent can report on its own sending.

metrics · events

Claude & Claude Code

Add the server plus four Claude Skills for end-to-end email workflows.

Cursor

Wire Drin into Cursor's MCP config and send straight from the editor.

Codex

Use the tools from OpenAI Codex, or fall back to the CLI and REST.

Agent inbox

The inbox & reply tools that let an agent receive mail, not just send.

// connect it

Hand your agent 54 email tools.
