Mailows — Claude Code MCP server: email for agents
Hands each AI agent its own inbox on your domain, with scoped OAuth grants you can revoke.
claude mcp add --transport http mailows https://mcp.mailows.com/mcpWhat Mailows does
Mailows is a remote MCP server reachable at https://mcp.mailows.com/mcp. Your agent gets a dedicated address on your domain instead of borrowing a human mailbox, and you choose which inboxes it can reach. Grants are revoked one agent at a time.
The first call opens a browser for OAuth, using authorization code with PKCE. Tokens live in the MCP client's credential store rather than in a project file. The service is operated by DW Technology LLC.
Because the server is hosted, mail passes through someone else's infrastructure. Teams with rules about where correspondence is stored should read the terms before wiring it in.
What it helps with
- give an agent its own address instead of a shared team mailbox
- read incoming mail and reply from inside a Claude session
- revoke one agent's access without touching the others
- limit which inboxes an agent can see
Example prompts for the agent
- Show unread mail in the agent inbox
- Reply to the latest message from the client
- List the inboxes you can access
