Use it from an AI agent — MCP + Agent connectors

MailKite speaks the Model Context Protocol: every API method is a tool your AI assistant (Claude, Cursor, …) can call — send mail, manage domains, search the docs, and give an agent its own inbox. Full guide: https://mailkite.dev/docs/ai-agents.

Hosted (recommended) — one-click OAuth, no key to copy:

claude mcp add --transport http mailkite https://mcp.mailkite.dev/mcp

In Claude Code you can also install the plugin:

/plugin marketplace add mailkite/claude-code
/plugin install mailkite@mailkite

Any chat/UI agent: "Add the MCP server at https://mcp.mailkite.dev/mcp and authenticate in the browser when prompted."

Local (static key, offline / CI):

{ "mcpServers": { "mailkite": { "command": "npx", "args": ["-y", "@mailkite/mcp"], "env": { "MAILKITE_API_KEY": "mk_live_…" } } } }

Give an agent its own inbox. Route inbound mail to a built-in inbox agent (the agent route action) and it answers, files, or escalates on its own — see https://mailkite.dev/docs/ai-agents.
