Read-only routeWhat you can ask once it is connected
“Who am I in Attio, and which workspace is connected? Do not change anything.”
“Find every contact at Acme in Attio and show their titles and emails.”
“Count open deals by stage in Attio. Do not change anything.”
“Log a note on the Acme company record that sums up today's call. Show me the note first.”
You choose what Claude is allowed to touch
Choose the saved accounts and tools this Claude connection may use. Its authorization carries that scope, and each app connection’s tool and resource restrictions still apply.
- Full accessEvery enabled tool on the connections you choose.
- Read onlyLooks things up, changes nothing.
- CustomPick apps and tools one by one.
- · The connection acts as the Attio user who signed in. Attio permissions set what it can reach; ApexGenius does not add a record-level allowlist.
- · The read route checks Attio's live tool labels and rejects writes or unlabeled operations.
- · Writes run right away. If the owner set a tool to Ask me first (approval mode always), the call returns approval_required; a person approves it in ApexGenius and you retry with the returned approval_request_id.
- · Merges and deleted comments cannot be undone here, and there is no delete for records, lists, notes or tasks. Remove those by hand in Attio.
- · query-particle-sql is not on every Attio plan, and Attio limits calls per workspace. Disconnecting stops future access; it does not undo a change that already ran.

Questions people ask first
How do I connect Attio?
Open Attio in ApexGenius Connections, choose Connect, and sign in to Attio in the browser. ApexGenius registers itself with Attio. You never paste an API key.
What can my AI read in Attio?
People, companies, deals and custom records, lists and their entries, notes, tasks, comments, synced meetings, call recordings and emails, plus reports. It sees only what your Attio user can see.
Can my AI change records?
Yes. It can create and update records, list entries, notes and tasks, and merge records. Writes run right away. If the owner set a tool to Ask me first (approval mode always), the call returns approval_required; a person approves it in ApexGenius and you retry with the returned approval_request_id.
Can it delete records?
No. Attio's MCP has no delete for records, lists, notes or tasks. The only delete is for a comment you created. Merges cannot be undone here.
Why did a SQL question fail?
query-particle-sql is not on every Attio plan. Ask the same question as a report instead; run-basic-report handles counts, sums and averages.
