How is access scoped?

OAuth on the Attio side — the connector sees what the connecting user can see. Workspace admins can disable third-party MCP access globally if a more restrictive posture is required.

Can it write records, or only read?

Both. The MCP exposes create/update tools for records, lists, and notes. Agents can move a deal stage, append a meeting note, or create a new person record from a natural-language prompt.

How does this compare to the community `kesslerio/attio-mcp-server` repo?

The community server is the right pick if you want self-hosted control over OAuth and secret storage. For the shortest path to a single workspace in Claude or ChatGPT, the first-party hosted MCP at `mcp.attio.com/mcp` is the recommended default.

Is there a rate limit?

Yes — Attio enforces per-workspace API limits. Tight agent loops can hit them; the server returns 429s as tool errors so the model can back off and retry.

Setup recipe

1
Install
No install snippet available yet — see the project’s README for setup instructions.
2
Set required secrets
No credentials required — this MCP runs over stdio without authentication.
3
Try a minimum working prompt
Update a deal stage and append a meeting note
In Attio, find the deal for Acme Corp, move it to "Negotiation" stage, and append a note dated today summarising: pricing was the main objection, decision expected by end of month.
Tested with: Claude Desktop, Claude Web, ChatGPT.

Tools & permissions

Tools list pending verification. The server exposes tools over MCP; we haven’t yet parsed its capability manifest into this page. Check the GitHub repo for the authoritative list.

Security & scope

Access scope: Read + write
Sandbox: Hosted by Attio. OAuth-scoped to the connecting user. Workspace admins can disable third-party MCP access at the workspace level.
Gotchas: A connected agent can update deal stages and create records — restrict the OAuth grant if the agent should only read.
Note attribution shows the OAuth user — agent-created notes appear under the connecting user's name in the activity feed.

Agent prompt pack

Paste into Claude, Cursor, or ChatGPT. Edit the [brackets] before sending.

Recommend the best MCP servers for [task: e.g. crm work] in [client: Claude].

Constraints:
- Prefer tools that are [official | open-source | read-only] — pick what matters for my use case.
- Exclude MCPs that require [e.g. a paid plan, OAuth-only flows, remote-only transport].
- Return at most 3 picks, ranked.

For each pick include:
1. One-sentence rationale.
2. The ready-to-paste install snippet for my client.
3. Any required secrets I need to create before installing.

Compare Attio against a real alternative. Swap the second MCP in [brackets] if you want a different match.

Compare Attio MCP vs [HubSpot MCP] for the following job: [describe the job, e.g. "let an agent create GitHub issues on bug triage"].

Judge them on:
- Setup time and complexity (what a new user hits first).
- Auth model (none / API key / OAuth 2.1) and credential risk.
- Transport (stdio / Streamable HTTP / SSE) and where the server runs.
- Required secrets and the blast radius if they leak.
- Operational risk in an unattended agent loop.
- Which one is "good enough" for a weekend prototype vs. production.

End with one sentence: which should I pick for my scenario, which is: [my scenario].

Asks the agent to install and verify. Works inside Claude Code, Cursor Agent, Codex CLI.

Install the Attio MCP server for my [client: Claude] at the default config path for that client.

Use the exact install snippet published at https://top-mcps.com/mcp/attio (fetch https://top-mcps.com/mcp/attio.json for the canonical server.json if you can read URLs).

Before finishing:
1. Create the required secrets (no secrets) and put them in the appropriate env block — do not hard-code them.
2. Restart or reload the client so it picks up the new server.
3. Verify the server is connected (green / running state) and at least one tool is listed.
4. If anything fails, read the client's MCP logs and report the exact error — do not silently retry.

Confirm when done and list the tools the server now exposes.
