npm install attio-mcp




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 languageβmanage Deals, Tasks, Lists, People, Companies, Records, and Notes without falling back to raw API calls.
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.
π 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"
> β οΈ 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:
- π Built-in Approval Flows: MCP safety annotations auto-approve read operations, request approval for writes
- π OAuth Integration: Self-hosted OAuth via Cloudflare Worker deployment
- π¬ Natural Language CRM: Manage your entire Attio workspace through conversational AI
- π Setup Guide: See ChatGPT Developer Mode docs and Cloudflare Worker Guide

- Configurable Limits: Override with MAX_PROMPT_TOKENS environment variableFor complete prompt documentation, see docs/prompts/v1-catalog.md.
β οΈ Known Limitations & Important Notes
$3
- 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$3
- Universal Tools: Primary interface (14 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- Lists API: Fully functional with complete CRUD operations (contrary to some outdated documentation)$3
- 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 35 tools are exposed by default (21 universal + 11 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.$3
- 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

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

---
β‘ Quick Start
$3
- Node.js (v18 or higher)
- Attio API Key (Get one here) or OAuth access token
- Attio Workspace ID
$3
The server supports two authentication methodsβboth use the same Bearer token scheme:
| Method | Environment Variable | Best For |
| ------------------------- | -------------------- | ------------------------------------ |
| API Key (recommended) |
ATTIO_API_KEY | Long-term integrations, personal use |
| OAuth Access Token | ATTIO_ACCESS_TOKEN | OAuth integrations, third-party apps |> 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.$3
`bash
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
`$3
`bash
Test the MCP server
attio-mcp --helpDiscover your Attio workspace attributes
attio-discover attributes
`$3
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
`bash
1. Copy the sample configuration to create your user config
cp configs/runtime/mappings/sample.json configs/runtime/mappings/user.json2. 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)> π‘ 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 topExample: 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
`json
{
"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"
}
}
}
`β
Good: Only custom/override fields
β Wasteful: Duplicating standard fields from default.json
> β οΈ 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"
`$3
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.`bash
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.`json
{
"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",
