Does Attio have an MCP server?

Yes. Attio runs a remote MCP server at mcp.attio.com/mcp, and its help centre says it's available on all plans and to all workspace members, as of September 2026. You connect it from Claude, ChatGPT or another MCP client and sign in with OAuth.

How do I connect Attio to Claude or ChatGPT?

Add Attio as a connector in the AI client. Attio's docs give the paths: in Claude, Settings, then Connectors, then Browse connectors; in ChatGPT, Apps, then search for Attio and connect. You then sign in to Attio, and the client can call its tools.

What are the Attio MCP rate limits?

Attio sets limits per workspace: 100 read requests a second, 25 write requests a second, 300 search requests a minute and 2 semantic-search requests a second, per its MCP docs in September 2026. Those limits are per workspace, so every user and agent on the same Attio workspace shares them.

Can the Attio MCP server see data I can't?

No. Attio says access is scoped to your authenticated account, so the AI client can only read and act on what you already have permission to see in the workspace. Connecting as a user with narrower rights narrows the agent too.

What can the Attio MCP server do?

It gives an AI client over 40 tools to read and write your Attio records, notes, lists and tasks, under your own workspace rights.

The short answer

Attio MCP lets Claude, ChatGPT or another MCP client search Attio records and create or update people, companies, deals, notes, lists and tasks.
Attio's MCP docs list 40+ tools in 11 categories, including record merge, meeting search, call recordings and SQL queries, as of September 2026.
Attio MCP is available on all Attio plans, uses OAuth, and is scoped to the signed-in user's own permissions.
Attio caps MCP traffic per workspace at 100 reads and 25 writes a second, so a careless bulk prompt can change a lot of data fast.

What the Attio tools cover

Attio groups its MCP tools around the objects you already use. Records come first: search, create, update and merge. Lists follow, with tools to add a record to a list and update a list entry. Notes, tasks and meetings each get their own tools.

Two tools go beyond the usual CRM set. One returns call recordings from meetings. Another runs SQL against your workspace data, so you can ask a reporting question in plain words and get a table back. You'll get most out of the server when a prompt mixes both, such as "find deals with no meeting in 30 days and add a follow-up task".

What to set up before an agent writes to Attio

Your user rights are the control. Attio's server inherits whatever the signed-in person may do, so an admin login hands the AI client admin reach. For an agent that runs on a schedule, sign in as a user whose role fits the job.

Watch merges most closely. A fuzzy prompt about "duplicates" can join records that only look alike, and your team then works from the wrong history. Ask for a list first, check it, then approve the merge yourself.

SalesCrew takes the same MCP idea and puts a review step in the middle. Its 140+ MCP tools each have a UI twin with identical effect. Stage changes, merges and every external send go to one approval queue by default, and each tool call is written to an audit log with the user, token or agent that made it. See the SalesCrew MCP server and SalesCrew vs Attio.

A bulk prompt moves at machine speed

Attio allows 25 writes a second per workspace, far faster than anyone can check by eye. Test a new prompt on a small list or a copy of a view before you let it loose on the whole workspace.
