# Agent integrations

> Give an AI agent its own email address. Drop the Drin MCP server into Claude, Cursor, Codex, and any MCP client — or wire it into LangChain, n8n, and other frameworks.

The Drin MCP server (`@drin00/mcp`) exposes the whole API as **54 tools** over
the Model Context Protocol. Any MCP-capable client can send and receive email,
manage domains and inboxes, and read metrics — with a single API key.

## MCP clients

<Warning>
  The MCP server acts with the **full authority of the key** you give it. Scope
  the key to a single project where you can, and store it in the client's `env`,
  never in source.
