Gmail MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Gmail and the rest of your systems. It gives your agent 79 Gmail actions (30 reads, 33 writes and 16 that wait for a confirmation) and holds the Gmail credential itself, so the agent never does. It paces Gmail's limits and records every call. Connecting Gmail needs your own Gmail OAuth app and one admin sign-in.

Set up

Connect Gmail in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Gmail.

    OAuth 2.0, authorization code with PKCE. You register your own OAuth app with Gmail, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key.

    Before the first sign-in, Gmail needs an OAuth app of your own, registered in its developer portal. actionlake has no Gmail app to lend you.

Top actions

The Gmail API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 54 of Gmail's 59 action names are shared with at least one other connector, so an agent learns them once.

The plan store

Ready-made plans for Gmail.

6 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The Gmail MCP server, answered.

Is there a Gmail MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 79 Gmail actions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Gmail.

What do I need to connect Gmail?

Your own Gmail OAuth app, registered with Gmail (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Gmail app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. The free call account { op: "connections.requirements", service: "gws_gmail" } lists exactly what to paste.

Can an AI agent delete or change things in Gmail?

Only if its key allows it, and only with an explicit confirmation. 16 Gmail actions are destructive, including permanently delete a Gmail message, permanently delete many Gmail messages and permanently delete a Gmail thread. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Gmail API limit?

actionlake paces every call to the limits in the Gmail service file: 6,000 calls a minute per connection. Repeated reads are answered from cache (28 Gmail actions can be), which never reaches Gmail.

What does a Gmail action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (12 Gmail actions page). Cache hits, searches, dry runs and calls Gmail refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Gmail API does it cover?

The Gmail API 1 at gmail.googleapis.com/gmail/v1. It is built from Gmail's documentation as read on 8 September 2026. 79 actions in 1 area, each one in the signed service file (version 1.0.0).

Does actionlake keep my Gmail data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Gmail credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
