AI agents · MCP

Give AI your mail.Keep the keys.

mailrust is an MCP server for your email, outreach and newsletters. Claude, ChatGPT, Cursor or your own agent works inside it, with the rights you set for each area and each mailbox.

01Connect

Two ways in.Same rules.

01

claude.ai and ChatGPT

Add a custom connector with your address. mailrust opens a consent screen: you see who asks and where it returns, and choose the rights.

https://mail.example.com/mcp
02

Claude Code, Cursor, your own

Create an agent under Agents, pick its rights and paste its key into the client. The key is shown once.

claude mcp add --transport http mailrust https://mail.example.com/mcp --header "Authorization: Bearer mra_..."
03

Then it works

The agent searches, reads, sorts, drafts and sends within its rights. Emails it writes wait under Agents until you press Send.

02Rights

Per area.Per mailbox.

Every agent gets its own set. New agents can only read mail until you give them more.

Rights decide

An agent sees only the tools its rights allow. Ask for more, and the person decides.

04Safety

Carefulby default.

Approval first

Emails an agent writes wait for a person. Sending on its own needs both the agent's right and the administrator's permission.

Nothing to steal

Agent keys and tokens are stored as fingerprints. A leaked database does not give anyone an agent's access.

Standard OAuth

OAuth 2.1 with PKCE, one-time codes, short tokens and refresh rotation. A replayed token cancels the whole sign-in.

One switch

The administrator can turn agents off for the whole installation or revoke any agent in a click.

Everything logged

Every email, change and approval lands in the audit log with the agent's name.

Every MCP client

The 2026-07-28 protocol and the earlier versions, so old and new clients both connect.
