Overview

AI-generated overview

Gives an AI assistant a real business email inbox on your own domain: read, search, draft, send, organise mail, manage mailboxes and aliases, and edit DNS…

What you can do
  • Read and search mail: list, read and search messages across mailboxes, threads, folders, attachments and contacts
  • Send mail: send single or templated batch messages, create, update and send drafts, schedule and cancel sends, check delivery status
  • Organise mail: flag, label, move, restore, mark spam or read, delete messages and empty trash
  • Manage account: list, create and update mailboxes, view account and setup summaries, list and create or delete aliases
  • Domains and DNS: list domains and DNS records, create, update and delete records
  • Drive: list and download files
When to use it
Useful when an agent should own a real address on your domain, for example setting up hello@ for a site it just built, receiving verification codes, triaging and answering a support inbox, or sending replies from your real address without a mail app.
Requirements
Remote streamable HTTP endpoint at faivelo.com with OAuth 2.1 browser sign-in on first call; no API key needed for interactive clients. Headless agents need an agent API key sent as an Authorization Bearer header. A Faivelo account is required, and MCP access is included on Growth plans and above and in the free trial.
Before you install
The assistant can send email, create and delete aliases, and create, update or delete DNS records for your domains, so review destructive actions before approving. Batch sends go to many recipients. Headless setups require an agent API key, which should be kept secret and scoped to the mailboxes it needs. Mail content and account data are handled by the Faivelo service, and paid plans start at $6/mo.

Installation

In SourceWeft

  1. Open Faivelo Email in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.faivelo%2Fmail/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Faivelo Email MCP server

[smithery badge] [Add to Cursor]

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 [email protected] 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

Any Agent Skills clientnpx skills add ethannschwartz/faivelo-mcp (the faivelo-email skill)
Other clients{ "mcpServers": { "faivelo": { "url": "https://faivelo.com/api/mcp" } } }

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

AreaTools
Readinglist_messages, read_message, get_thread, search_messages, search_all_mailboxes, list_folders, get_attachment, get_contacts
Sendingsend_message, send_batch (one templated email to many recipients, queued and paced server-side), get_batch_status, create_draft, update_draft, send_draft, list_scheduled, cancel_scheduled, get_delivery_status
Organisingflag_message, label_message, move_message, restore_message, mark_spam, mark_all_read, delete_message, empty_trash
Accountlist_mailboxes, create_mailbox, update_mailbox (set the name a mailbox sends as), get_account_summary, get_setup_summary, get_domain_setup (a domain's DNS records, found or missing), list_aliases, create_alias, delete_alias
Domains & DNSlist_domains, list_dns_records, create_dns_record, update_dns_record, delete_dns_record
Drivedrive_list_files, drive_download_file

send_message and send_batch take from as "[email protected]" or "Support Bot <[email protected]>"; 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.
