Attio MCP servers: which one to use
Use Attio's own hosted server for Claude or ChatGPT. Pick a community server if you want an API key or a setup that only reads your CRM.

Attio publishes an official server that you add to Claude or ChatGPT and sign in to with your Attio account. It can search records, log notes and tasks, and its docs say reads are auto-approved while writes ask for confirmation. The community servers run with an Attio API key. One lists only search and read tools, and another can be limited to search.
Good for
- Sales and revenue teams who want Claude to look up contacts, log notes and move deals
- Anyone who wants an assistant to read their CRM but never edit it
- Developers who run a server with their own Attio API key
- Teams that want to combine Attio data with Slack or Linear in one assistant
Which Attio MCP server to use
Use Attio's own server unless you need to stop the assistant from changing data. For that, pick the Red River West server, whose README lists only search and read tools, or the most used community server, which has a search-only mode.

Questions
Is there an official Attio MCP server?
Yes. Attio runs a hosted server at https://mcp.attio.com/mcp and lists a connector for Claude. You sign in with your Attio account.
Which Attio MCP server should I use?
Use Attio's own server. It needs no API key and acts with your own Attio permissions. Use a community server if you want to run it yourself with an API key.
Is there a read-only Attio MCP server?
Yes, two community ones. The Red River West server lists only search and read tools, and the kesslerio server can be limited to search and fetch with ATTIO_MCP_TOOL_MODE: 'search'. Attio's own server asks for confirmation on writes and auto-approves reads.
Is the Attio MCP server free?
Attio's help center says Attio MCP is available on all plans, though query-particle-sql is not on every billing plan. The community servers in this table are MIT or Apache 2.0 licensed.
Do I need an Attio API key?
Not for Attio's own server, where you sign in with your account. The community servers in this table take an Attio API key.
Can the Attio MCP server delete records?
Partly. Attio's tool list names delete-task and delete-comment (comments you created), plus merge-records, which merges two records into one. For records it names create, update and upsert tools.
Does it work in ChatGPT?
Yes. Attio's MCP docs give ChatGPT steps: open Apps, search for Attio and connect. For other clients, add https://mcp.attio.com/mcp as a remote server and sign in.
How do the Attio MCP server and Ask Attio differ?
Ask Attio is the AI inside Attio and needs no setup. The MCP server lets you work from an outside assistant and combine your CRM with other tools like Slack or Linear.
