Attio MCP Server

npm version

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
• 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

⚠️ Known Limitations & Important Notes

Current Limitations

• Field Parameter Filtering: Tasks endpoint /objects/tasks/attributes has limitations, handled with fallback patterns
• Pagination: Tasks pagination uses in-memory handling due to API constraints

API Compatibility

• Universal Tools: Primary interface (19 tools) - recommended for all new integrations
• Legacy Tools: Available via DISABLE_UNIVERSAL_TOOLS=true environment variable (deprecated)
• Lists API: Fully functional with complete CRUD operations (contrary to some outdated documentation)

🤝 OpenAI MCP Compatibility

• Developer Mode Ready: Every tool now publishes MCP safety annotations (readOnlyHint, destructiveHint) so OpenAI Developer Mode can auto-approve reads and request confirmation for writes.
• Full Tool Access (Default): All 41 tools are exposed by default (26 universal/OpenAI + 12 list + 3 workspace member). Do NOT set ATTIO_MCP_TOOL_MODE in Smithery configuration for full access.
• Search-Only Mode: To restrict to read-only tools (search, fetch, aaa-health-check), explicitly configure ATTIO_MCP_TOOL_MODE: 'search' in Smithery dashboard when Developer Mode is unavailable.
• Detailed Guide: See docs/chatgpt-developer-mode.md for environment variables, approval flows, and validation tips.
• User Documentation: See the ChatGPT Developer Mode docs for a complete walkthrough of approval flows and setup instructions.

Performance Considerations

• Batch Operations: Optimized with chunking, rate limiting, and error recovery
• Large Datasets: Automatic pagination and field filtering for optimal performance
• Rate Limiting: Built-in protection against API rate limits with exponential backoff

For detailed troubleshooting and solutions, see TROUBLESHOOTING.md and GitHub Issues.

🎯 Advanced Search Filters

Build powerful CRM queries with multi-criteria AND/OR filtering. See the Advanced Search Guide for complete examples and operator reference.

🚀 Installation

⚠️ IMPORTANT: Correct Package Name

The npm package name is attio-mcp (not attio-mcp-server). The GitHub repository is named attio-mcp-server, but the npm package was renamed to attio-mcp in June 2025. Installing attio-mcp-server will give you an outdated v0.0.2 release with only 4 legacy tools.

Client Compatibility

Choose your installation method:

• Most users: Use Tier 1 (Shell Installers) - one command, automatic setup
• Power users: Use Tier 2 (Manual) - full control over configuration
• ChatGPT/Teams/Enterprise: Use Tier 3 (Cloudflare Worker) - self-hosted, multi-user OAuth

Tier 1: Shell Installers

Best for: Developers who prefer local installations with automatic configuration.

Tool Name Changes

Action Required: Update your integrations to use new tool names before Q1 2026. See MIGRATION-GUIDE.md for the complete migration table.

⚡ Quick Start

Prerequisites

• Node.js (v18 or higher)
• Attio API Key (Get one here) or OAuth access token
• Attio Workspace ID

🔐 Authentication Options

The server supports two authentication methods—both use the same Bearer token scheme:

Note: If both are set, ATTIO_API_KEY takes precedence.

OAuth Users: For detailed setup including PKCE flow and token refresh, see OAuth Authentication Guide.

1. Set Environment Variables

# Option 1: API Key (recommended for most users)
export ATTIO_API_KEY="your_api_key_here"

# Option 2: OAuth Access Token (for OAuth integrations)
# export ATTIO_ACCESS_TOKEN="your_oauth_access_token_here"

export ATTIO_WORKSPACE_ID="your_workspace_id_here"

# Optional: Deal defaults configuration
export ATTIO_DEFAULT_DEAL_STAGE="Interested"           # Default stage for new deals
export ATTIO_DEFAULT_DEAL_OWNER="user@company.com"     # Default owner email address (see below)
export ATTIO_DEFAULT_CURRENCY="USD"                    # Default currency for deal values

2. Test the Installation

# Test the MCP server
attio-mcp --help

# Discover your Attio workspace attributes
attio-discover attributes

3. 🎯 CRITICAL: Configure Field Mappings

The MCP server uses field mapping files to translate between natural language and Attio's API field names. This configuration is essential for proper operation.

Quick Setup

# 1. Copy the sample configuration to create your user config
cp configs/runtime/mappings/sample.json configs/runtime/mappings/user.json

# 2. Edit user.json to match your workspace's custom fields
# Focus on the "objects.companies" and "objects.people" sections

Configuration Files (in configs/runtime/mappings/)

• default.json - Standard Attio CRM fields (loaded first, don't edit)
• sample.json - Examples with custom field templates (copy from this, not used at runtime)
• user.json - YOUR workspace-specific overrides (merged on top of default.json)

💡 Key Insight: user.json is merged on top of default.json, so only include overrides and additions. Don't duplicate mappings that already exist in default.json.

How Configuration Merging Works

The MCP server loads configuration in this order:

1. default.json - Contains all standard Attio fields (Name, Description, Team, etc.)
2. user.json - Your custom additions/overrides are merged on top

Example: If default.json has "Name": "name" and your user.json also has "Name": "name", that's wasted tokens. Only include fields that are:

• New custom fields (not in default.json)
• Different mappings (overriding default behavior)

Optimized user.json Example

{
  "mappings": {
    "attributes": {
      "objects": {
        "companies": {
          "// Only your custom fields - defaults are inherited": "",
          "Lead Score": "lead_score",
          "B2B Segment": "b2b_segment",
          "Industry Vertical": "custom_industry_field"
        }
      }
    },
    "lists": {
      "// Only your specific lists": "",
      "Sales Pipeline": "your-pipeline-list-id"
    }
  }
}

✅ Good: Only custom/override fields
❌ Wasteful: Duplicating standard fields from default.json

⚠️ Without proper mapping configuration, the MCP server may not work correctly with your custom fields and lists.

Next: Verify your field mappings work by testing with Claude:

"Find companies in our pipeline with lead score > 80"

4. Configure Claude Desktop

Add to your Claude Desktop MCP configuration:

Finding Required IDs

Deal Owner Email (for deal owner defaults): The ATTIO_DEFAULT_DEAL_OWNER should be set to the email address of the workspace member who should own new deals by default. This is typically your own email address or the email address of your sales team lead.

# Example:
export ATTIO_DEFAULT_DEAL_OWNER="john.smith@company.com"

Note: The system will automatically resolve email addresses to workspace member references when creating deals.

Deal Stages: Deal stages are specific to your workspace. Check your Attio workspace settings or use the discover-attributes command to find available stages for deals.

{
  "mcpServers": {
    "attio-mcp": {
      "command": "attio-mcp",
      "env": {
        "ATTIO_API_KEY": "your_api_key_here",
        "ATTIO_WORKSPACE_ID": "your_workspace_id_here",
        "ATTIO_DEFAULT_DEAL_STAGE": "Interested",
        "ATTIO_DEFAULT_DEAL_OWNER": "user@company.com",
        "ATTIO_DEFAULT_CURRENCY": "USD"
      }
    }
  }
}

🔐 Security & Privacy

• Secure API Authentication: Industry-standard API key authentication
• No Data Storage: Direct API passthrough with no local data retention
• Open Source: Full transparency with Apache 2.0 license
• Optional On-Premises: Deploy in your own infrastructure
• npm Provenance: Published with Sigstore provenance — every release is cryptographically linked to the GitHub Actions build and source commit

Supply Chain Verification

This package is published with npm provenance, creating a verifiable chain from source code to published artifact. Verify a release:

# Check provenance attestation on any published version
npm view attio-mcp --json | jq .attestations

# With pnpm (v10+), enforce trust policy at install time
# pnpm trustPolicy: no-downgrade blocks packages published with weaker credentials

For maximum supply chain protection, install with pnpm v10+ which enforces:

• trustPolicy: no-downgrade — blocks versions published with weaker credentials than prior versions
• minimumReleaseAge — cooldown period before new versions can be installed
