19 Best Email MCP Servers, Compared (October 2026)

Updated 19 of 3,021 Email servers in the Glama registryRebuilt weekly

The short answer

For most readers who want Gmail and Calendar control through an AI assistant, reach for Google Workspace MCP Server. It exposes 120 tools, had a commit 0 days ago, has 708 commits on its default branch in the last 12 weeks, and had 41,020 PyPI downloads in a typical week. If you need IMAP and SMTP rather than Google Workspace, MCP Email Server is the better fit: it exposes 21 tools and had 2,888 PyPI downloads in a typical week. If your mail runs through Microsoft 365 and you also need OneDrive, Excel, and calendar access, Microsoft 365 MCP Server exposes 197 tools and had 40,558 npm downloads in a typical week.

Whichever you choose, give it the narrowest access that still works (a read-only credential, a replica, a scratch account), and widen it only once you have watched what your agent actually asks for.

Glama operates the MCP registry these numbers are measured from, and sells MCP hosting and a gateway. No position on this page is paid for. How the registry is built.

The ranking, with the evidence

Each position is a weighted mean of adoption (40%), maintenance (24%), momentum (14%), tool description quality (13%) and trust (9%), multiplied by three attenuators: how directly the server is about Email (named for it, declaring it, tagged with it, or merely mentioning it), whether its repository is still moving, and how much independent evidence of adoption it has. Open the score on any entry to see every number, including the ones marked ≈, which were imputed from the median of the other candidates rather than measured. The maintenance grade on each entry is mostly issue responsiveness, release recency and open security alerts rather than commits, so a recent commit beside a low grade is two different measurements rather than a contradiction.

  • Abandoned but popular: People use it, but its default branch has stopped moving. Fine to keep running, risky to adopt.
  • Community favourite: Widely adopted and still actively maintained.
  • Dormant: Neither changing nor widely adopted. Here because it still matches the search.
  • Emerging: Small audience, growing quickly, maintained. The bet with the most upside.
  • Steady: Maintained, modest audience, no surprises in either direction.

    Google Workspace MCP Server - Control Gmail, Calendar, Docs, Sheets, Slides, Chat, Forms & Drive

    Community favouriteNo change
    taylorwilsdon/google_workspace_mcp ↗

    Best for: Gmail and Calendar management through an AI assistant: it exposes Gmail search, read, send, draft, label, and filter tools plus Calendar event tools.

    The server exposes 120 tools, including Gmail search, message and thread retrieval, attachment download, send, draft, label, and filter tools, plus Google Drive and Calendar tools. A prerequisite is Google Cloud OAuth client credentials and an authenticated Google account, because its tools act through Google's APIs on behalf of the user.

    Best for: Personal Outlook.com, Hotmail or Live accounts that need mail, calendar, contacts and tasks in one agent: 68 typed Graph tools including delta-sync for polling loops.

    Apple Mail MCP Server

    Community favourite▲ 2
    patrickfreyer/apple-mail-mcp ↗

    Best for: Triage and drafting inside a Mac's Apple Mail accounts: it exposes reply, forward, draft, thread, and needs-response tools that operate on Mail's own mailboxes.

    The server wraps Apple Mail through FastMCP, exposing 26 tools for listing accounts and mailboxes, searching and threading mail, composing, replying and forwarding, managing drafts and attachments, and inbox analytics such as awaiting-reply and top-sender reports. It requires macOS with Apple Mail already configured and Python 3.10 or later, and sending can be blocked by starting it with the --read-only flag.

    Best for: Automating a personal Outlook.com or Microsoft 365 mailbox: it exposes 22 tools across mail, calendar, contacts and rules, with dry-run previews before sends.

    It connects a Microsoft account to an MCP client through 22 tools covering email search, read, send and draft, calendar events, contacts, folders, inbox rules, categories, Focused Inbox and mailbox settings, with an auth tool managing the Graph session. Shared mailbox support is read and organise only: sending, drafts, replies and forwards always act on the signed-in user's own mailbox, and it requires a personal Outlook.com or work/school Microsoft 365 account.

    Best for: Managing Apple Mail on macOS from an AI assistant: it exposes search, send, draft, reply, forward, move, and batch tools that act locally through AppleScript.

It runs only on macOS, prompts for automation permission on first use, and its optional fast IMAP reads and clean SMTP sending each require a separate one-time setup.

    Best for: Agents that must send and receive real email without a third-party API: it runs a local mail server with disposable inboxes and verification-code fetching.

    AgenticMail exposes 100 tools for sending, replying to, forwarding, searching, and organizing email, managing folders, drafts, scheduled mail, contacts, tags, signatures, and templates, and messaging other agents, plus setup tools for a Gmail/Outlook relay or a Cloudflare domain. Reaching the real internet depends on configuring one of those two gateway modes, and the account, relay, and domain setup tools require a master API key.

    Best for: Investigating an email address across breaches, pastes, GitHub, and DNS: it exposes those lookup tools over MCP and can chain them from one target.

    OpenOSINT exposes 20 OSINT lookup tools through an MCP server, with a REPL, CLI, and browser Web UI documented as alternative interfaces. Before choosing it, note that several lookups require third-party API keys, including HIBP_API_KEY for breach checks and VIRUSTOTAL_API_KEY for reputation checks, so those capabilities are unavailable without the relevant credentials.

    Mailgun MCP Server

    Community favouriteNew
    mailgun/mailgun-mcp-server ↗

    Best for: Mailgun users wanting an assistant to send email and check delivery stats: it registers 70 Mailgun API tools for sending, domains, webhooks, and analytics.

    It is an OpenAPI-driven stdio server that registers 70 Mailgun API tools generated from a bundled spec, spanning sending and resending mail, stored-message retrieval, domain and webhook management, mailing lists, templates, suppressions, IP pools, and sending analytics. Running it means a local install with Node.js v20.12 or higher and a Mailgun API key, since no hosted version is offered, and its tools are limited to read and update operations with no delete calls exposed.

Questions people ask

How do I choose between Google Workspace MCP Server and MCP Email Server?

Choose Google Workspace MCP Server if you want Gmail and Calendar tools in one assistant: it exposes 120 tools and had 41,020 PyPI downloads in a typical week, with 708 commits on its default branch in the last 12 weeks. Choose MCP Email Server if you need IMAP and SMTP for reading, sending, organizing, tagging, moving, archiving, and attachments: it exposes 21 tools, has a tool description grade of A, and had 2,888 PyPI downloads in a typical week. The Google server is built around Google Workspace, while the IMAP/SMTP server is the better fit when your mail is not in Google Workspace.

What does Gmail MCP Server (ArtyMcLabin fork) require before it will run?

It is a Gmail MCP server with configurable OAuth scopes, so plan for Google OAuth configuration for the account you want it to use. Its intended client is a local stdio MCP client, and it is built for reply threading, reply-all, send-as aliases, and thread-level operations. Its default branch had a commit 67 days ago and 1 commit in the last 12 weeks, so check its current state before relying on it for new work.

Does Email Sending MCP work with any email provider?

Email Sending MCP is built around Resend's API, so it fits Resend users rather than any arbitrary mailbox. It exposes 136 tools for managing email broadcasts, contacts, and automations, and had 12,866 npm downloads in a typical week. If your sending does not go through Resend, look at MCP Email Server for IMAP and SMTP instead.

What should I be careful about when pointing an agent at Microsoft 365 MCP Server?

Microsoft 365 MCP Server logs into Microsoft accounts and exposes 197 tools, so the tool surface is broad. Its tool description grade is B, which is below the A grade on several narrower mail servers. It had a commit 0 days ago and 100 commits on its default branch in the last 12 weeks, so it is active, but you should still decide which Microsoft 365 resources the agent needs before connecting it.

Which Apple Mail server should I use?

apple-mail-mcp exposes 52 tools for search, send, draft, reply, forward, move, and batch actions through AppleScript, and had 138 commits on its default branch in the last 12 weeks. Apple Mail MCP Server exposes 26 tools for triage and drafting, including reply, forward, draft, thread, and needs-response tools, and had a commit 2 days ago with 4 commits in the last 12 weeks. Use apple-mail-mcp when you want the larger measured tool set and more recent commit activity; use Apple Mail MCP Server when its triage and drafting workflow matches your needs.
