Faivelo Email

Faivelo Email MCP server

Give Claude, ChatGPT, Cursor, Codex or any AI agent a real email inbox on your own domain. Your assistant can read and search your mail, draft and send replies, schedule sends, file messages away, create new addresses for itself, and fix your domain's DNS. You choose exactly which mailboxes it can see.

Useful when you want to:

• let your coding agent set up hello@yourcompany.com for the site it just built
• give an AI agent its own address to sign up for services and receive verification codes
• triage, summarise and answer a support inbox from Claude
• send a reply from your real address without opening a mail app

Server URL: https://faivelo.com/api/mcp (streamable HTTP, OAuth 2.1, no API key to paste) Registry name: com.faivelo/mail Access: a Faivelo account. MCP is included on Growth and up, and in the free trial (no card). Plans

Install

The first call opens a browser sign-in, where you choose exactly which mailboxes the assistant can reach.

Headless agents (no browser): send an API key instead, Authorization: Bearer fvl_live_.... Create an *agent* key at Settings → Developers; it only reaches the mailboxes it creates or is granted.

Cursor

Two ways in. Both sign you in through the browser on the first call; there is no key to paste.

• Plugin (once it is listed on the Cursor Marketplace): type /add-plugin faivelo in the agent chat, or find Faivelo under Settings → Plugins. The plugin installs the MCP server, the faivelo-email skill and a rule that teaches the agent to set up email on a domain, send from an app and verify webhooks.
• Server only: Add to Cursor, or put { "mcpServers": { "faivelo": { "url": "https://faivelo.com/api/mcp" } } } in .cursor/mcp.json (this project) or ~/.cursor/mcp.json (every project). Add "headers": { "Authorization": "Bearer fvl_live_..." } for a headless setup.

Cursor sends at most about 40 tools to the model across every MCP server you have enabled. Faivelo exposes 30 to 34 tools on an OAuth connection (38 with an API key), so if you run other servers alongside it, switch off the tools you do not need in Cursor's MCP settings; the Drive tools (drive_list_files, drive_download_file) and the scheduling tools (list_scheduled, cancel_scheduled) are the usual first picks.

Tools

send_message and send_batch take from as "bot@yourdomain.com" or "Support Bot "; a name there (or fromName) is the From name for that message only. Give each mailbox a lasting name with displayName on create_mailbox or with update_mailbox; a send from a mailbox with no name anywhere returns a hint saying so.

get_setup_summary returns a shareable markdown summary of what is set up (domains, DNS state, mailboxes, what is still pending), for an agent to hand to its human when it finishes.

Every tool declares readOnlyHint / destructiveHint, so clients can ask before anything that sends or deletes.
