Attio MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Attio and the rest of your systems. It gives your agent 91 Attio actions (43 reads, 35 writes and 13 that wait for a confirmation) and holds the Attio credential itself, so the agent never does. It paces Attio's limits and records every call.

Set up

Connect Attio 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.

  2. 02

    Connect Attio.

    Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Top actions

The Attio API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 76 of Attio's 77 action names are shared with at least one other connector, so an agent learns them once.

Each one names the Attio actions it will call, so you know what it reads and what it changes before you send it.

The plan store

Ready-made plans for Attio.

8 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.

Governance for Attio

Destructive actions wait for a yes.

13 Attio actions are destructive. These are all of them:

  • Delete an Attio noteattio.notes.delete
  • Delete an Attio meetingattio.meetings.delete
  • Delete an Attio taskattio.tasks.delete
  • Merge two Attio recordsattio.record_merges.create
  • Delete an Attio activity recordattio.activity_records.delete
  • Delete an Attio list entryattio.list_entries.delete
  • Delete an Attio fileattio.files.delete
  • Delete an Attio call recordingattio.call_recordings.delete

  • Delete an Attio recordattio.records.delete
  • Delete an Attio objectattio.objects.delete
  • Delete an Attio activity typeattio.activities.delete
  • Delete an Attio commentattio.comments.delete

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 Attio MCP server, answered.

Is there an Attio MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 91 Attio actions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Attio.

What do I need to connect Attio?

Attio access token or workspace API key. The free call account { op: "connections.requirements", service: "attio" } lists exactly what to paste.

Can an AI agent delete or change things in Attio?

Only if its key allows it, and only with an explicit confirmation. 13 Attio actions are destructive, including delete an Attio note, delete an Attio meeting and delete an Attio task. 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 Attio API limit?

actionlake paces every call to the limits in the Attio service file: 100 calls a second per connection. Repeated reads are answered from cache (43 Attio actions can be), which never reaches Attio.

What does an Attio action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (19 Attio actions page). Cache hits, searches, dry runs and calls Attio 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 Attio API does it cover?

The Attio API v2 at api.attio.com. It is built from Attio's documentation as read on 18 September 2026. 91 actions in 1 area, each one in the signed service file (version 1.0.0).

Does actionlake keep my Attio 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 Attio 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.
