Attio MCP Server

Attio MCP Server

A comprehensive Model Context Protocol (MCP) server for Attio, providing complete CRM surface coverage. This server enables AI assistants like Claude and ChatGPT to interact directly with your entire Attio workspace through natural language—manage Deals, Tasks, Lists, People, Companies, Records, and Notes without falling back to raw API calls.

🎯 What is Attio MCP Server?

Transform your CRM workflows with AI-powered automation. Instead of clicking through multiple screens, simply ask Claude or ChatGPT to find prospects, update records, manage pipelines, and analyze your data using natural language commands.

🎉 v1.0.0 Milestone: Complete Attio CRM surface coverage with full ChatGPT Developer Mode integration.

"Find all AI companies with 50+ employees that we haven't contacted in 30 days and add them to our Q1 outreach list"

🚀 ChatGPT Developer Mode Integration

⚠️ Smithery Temporarily Unavailable: Smithery has changed their deployment model to require external hosting. We're working on Cloudflare Worker hosting for ChatGPT users. In the meantime, use Tier 4 (Cloudflare Worker) for ChatGPT/remote access.

ChatGPT Pro/Plus users can access the Attio toolset through natural language using a self-hosted Cloudflare Worker:

• 🔐 Built-in Approval Flows: MCP safety annotations auto-approve read operations, request approval for writes
• 🌐 OAuth Integration: Self-hosted OAuth via Cloudflare Worker deployment
• 💬 Natural Language CRM: Manage your entire Attio workspace through conversational AI
• 📖 Setup Guide: See ChatGPT Developer Mode docs and Cloudflare Worker Guide

✨ Core Features & Implementation Status

🎯 Universal Tools Architecture (19 Universal Operations)

Focused Tool Surface: Consolidated 40+ resource-specific tools into universal operations, then added scoped high-frequency write tools for safer company and deal updates.

• High Performance: 89.7% speed improvement with 227KB memory reduction (PR #483)
• Enterprise Quality: 97.15/100 production readiness score with zero breaking changes
• Clean Architecture: Complete production-test separation with mock factory pattern
• Structured Results: Every default tool advertises a validated output schema; see the result contract for list, member, diagnostic, and connector outputs, and the preceding sections for universal outputs and prose opt-out
• Scoped Tool Policy: Add scoped default tools only when the workflow is frequent, a generic write can mutate the wrong object class, and the scoped tool removes a model decision instead of merely renaming a universal call

📋 Lists & Pipeline Management (6 Tools + 8 Deprecated)

• Active Tools: 4 consolidated tools with auto-mode detection (Migration Guide)
• list_entries_filter - Unified filtering with 4 modes
• list_entries_manage - Unified entry management with 3 modes
• list_entries_list - Retrieve list entries
• records_get_list_memberships - Find record's list memberships
• List Configuration Tools (dedicated; universal records_create/records_update reject resource_type: "lists"):
• lists_create - Create lists with first-class access controls: workspace_access (full-access \| read-and-write \| read-only \| "null" for a private list) and workspace_member_access (per-member grants). Omitting both access fields defaults the new list to workspace-wide full access; new lists must keep at least one full-access grantee.
• lists_update_configuration - Update name, custom fields, and the same access controls. Member-level grants can raise access above the workspace default but never lower it below workspace_access.
• Errors distinguish plan_gating (workspace plan does not support the requested access configuration) from permission_failure (token/workspace permissions) and unsupported_input (malformed access config), each with a suggested next step.
