Attio MCP Server

A high-performance Model Context Protocol (MCP) server that provides seamless access to the Attio API, enabling AI assistants like Claude and Cursor to interact with your Attio workspace through human-readable tools.

Features

• 🏷️ Human-Readable Tool Names: Automatically transforms technical API names (like getv2objects) into clear, categorized names (like list_objects)

• 📊 Full API Coverage: Access to objects, records, attributes, lists, tasks, notes, and more

• 📁 Organized by Category: Tools are grouped into logical categories for easy navigation

• 🤖 AI Assistant Ready: Works seamlessly with Claude Desktop and Cursor

• ⚡ High Performance: Built with Bun for fast execution and native TypeScript support

• 🔧 Easy Installation: Automated setup scripts with intelligent configuration detection

Quick Start

1. Prerequisites:

   # Install Bun (if not already installed)
   curl -fsSL https://bun.sh/install | bash

2. Install and configure:

   ./install.sh

3. Add your Attio access token to .env:

   ATTIO_ACCESS_TOKEN=your_token_here

   Get your token from: https://app.attio.com/settings/api

4. Restart Claude Desktop or Cursor

Manual Installation

For Claude Desktop

./install-claude.sh

This will automatically:

• Add the server to Claude's configuration

• Configure authentication with your access token

• Create a backup of existing configuration

For Cursor

./install-cursor.sh

This will automatically:

• Add the server to Cursor's settings

• Configure authentication with your access token

• Create a backup of existing settings

Available Tools

The MCP server exposes all Attio API endpoints as tools with human-readable names, organized by category:

Core Data Management

• Objects: list_objects, create_object, get_object, update_object

• Records: list_records, create_record, query_records, delete_record

• Attributes: list_attributes, create_attribute, update_attribute_status

Lists & Entries

• Lists: list_lists, create_list, update_list

• Notes: list_notes, create_note, get_note, delete_note

• Comments: create_comment, get_comment, list_comment_threads

Administration

• Workspace: list_workspace_members, get_workspace_member

• Webhooks: list_webhooks, create_webhook, update_webhook

• Authentication: get_current_user

Manual Testing

To test the server directly:

bun start

Configuration

The server uses the following environment variables:

• ATTIO_ACCESS_TOKEN: Your Attio workspace access token (required)

• PORT: Port for web transport (default: 3000)

• LOG_LEVEL: Logging level (default: info)

Troubleshooting

1. Server not showing in Claude/Cursor:

   • Restart the application after installation

   • Check the logs for any errors

   • Ensure the server is built: bun run build

2. Authentication errors:

   • Verify your access token in .env

   • Ensure the token has the necessary permissions

3. Build errors:

   • Run bun install to ensure all dependencies are installed

   • Run bun run build to compile TypeScript

Development

To modify the server:

1. Edit src/index.ts

2. Run bun run build

3. Test with bun test

4. Restart Claude/Cursor to load changes
