Getting Started

Prerequisites

Before connecting Attio MCP, ensure you have:

An active Attio workspace
An MCP-compatible AI client (Claude Desktop, Claude.ai, ChatGPT, Cursor, etc.)

Connecting to Attio MCP

Attio MCP uses OAuth authentication, so you simply log in with your Attio account—no API keys required.

Add as a Custom Connector

In your AI tool of choice, add the following URL as a custom MCP connector:

https://mcp.attio.com/mcp

For Claude Desktop or Claude.ai:

Open Settings -> Connectors -> Browse connectors
Search for Attio
Install Attio

For ChatGPT:

Open Apps
Search for Attio
Connect Attio

For other MCP clients: Add https://mcp.attio.com/mcp as a remote MCP server and complete the OAuth authentication when prompted. Once connected, you’ll be authenticated as your Attio user with access to your workspace data.

Supported Tools

Now that you have installed Attio MCP, let’s explore how AI assistants can use these tools to search, create, and manage content in your Attio workspace. These tools work seamlessly together through prompts, and their real power comes from combining them. With a single prompt, you can search your workspace, create new records, log notes, and manage tasks. Understanding these building blocks helps you craft efficient prompts that tackle complex workflows.

Rate Limits

Attio MCP applies per-workspace rate limits to tool calls. Tools are grouped into tiers, and each tier has its own limit. Tools in the same tier share a single bucket per workspace, so calls to any tool in a tier count against the same limit.

Tier	Limit	Tools
Read	100 requests / second	`get-call-recording`, `get-email-content`, `get-note-body`, `get-records-by-ids`, `list-attribute-definitions`, `list-comment-replies`, `list-comments`, `list-list-attribute-definitions`, `list-lists`, `list-records`, `list-records-in-list`, `list-tasks`, `list-workspace-members`, `list-workspace-teams`, `whoami`
Write	25 requests / second	`add-record-to-list`, `create-comment`, `create-note`, `create-record`, `create-task`, `delete-comment`, `update-list`, `update-list-entry-by-id`, `update-list-entry-by-record-id`, `update-note`, `update-record`, `update-task`, `upsert-record`
Search	300 requests / minute	`search-call-recordings-by-metadata`, `search-emails-by-metadata`, `search-meetings`, `search-notes-by-metadata`, `search-records`
Semantic search	2 requests / second	`semantic-search-call-recordings`, `semantic-search-emails`, `semantic-search-notes`
Reporting	2 requests / second	`run-basic-report`

The Read and Write tiers match the equivalent REST API rate limits.

What to do if you’re rate-limited

If you encounter rate limit errors:

Prompt your AI tool to reduce parallel operations
Space out sequential requests
Try again after a brief waiting period

In most cases, normal conversational use stays well within rate limits.
