Your CRM, Inside Your Chat

This MCP server puts your Attio workspace right inside Claude. Ask your agent to pull up any customer or deal details with `get_record`. You can also check what's in a specific pipeline stage using `get_list_entries`. It's way faster than hunting through the Attio UI. Need to make a change? Just tell your agent what to do. You can `update_record` with new info, `create_record` for a new lead, or `delete_record` when it's time to clean up. It all happens through conversation, so you stay focused.

Log Notes and Run Your To-Do List

This tool logs notes and tasks directly to any record in Attio. Just finished a sales call? Tell Claude to `create_note` with a summary and attach it to the right company. You won't forget to log the important details ever again. It also runs your to-do list. Ask your agent to `create_task` for a follow-up, or use `list_tasks` to see what's on your plate for the day. Your whole sales workflow is right there in the chat.

Figure Out Your Attio Data Model

Attio’s data model is flexible, which is great until you forget a custom field name. This server lets you inspect your own setup. Use `list_objects` to see all the objects you've created, like 'Companies' or 'Deals'. Once you know the object, you can dig deeper with `get_object` to see its exact schema and all the available attributes. It's a quick way for anyone on the team to learn how your CRM is structured without digging through settings pages.
