BukaA 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.
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"
⚠️ 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:

capabilities_get (full mode only) publishes the permitted capability
manifest: for every tool this server advertises, its input and output schemas
plus the operation facts — action, resource types, read-only/destructive/
idempotent flags, whether a credential is required, pagination style and cap,
and guidance on capability, boundaries, limits, and recovery.aaa-health-check returns the same manifest for its permitted set, projected
to its operation sections, so a search-only client can see what it is allowed
to use without widening its allowlist. Schema documents come from
capabilities_get or tools/list; the health payload says so in
capabilities.projection.A listed tool is configured, not granted. Authorization is still enforced on every call, so a manifest entry can still come back denied.

Best for: Teams needing centralized OAuth, multi-user access, mobile access, or running MCP without local installation.
Deploy your own Attio MCP server on Cloudflare Workers with full OAuth 2.1 support.
Mobile Access: With a remote MCP server, you can use Attio tools from:
cd examples/cloudflare-mcp-server
npm install
wrangler kv:namespace create "TOKEN_STORE"
# Update wrangler.toml with the KV namespace ID
wrangler secret put ATTIO_CLIENT_ID
wrangler secret put ATTIO_CLIENT_SECRET
wrangler secret put TOKEN_ENCRYPTION_KEY
wrangler deploy
After deployment, configure your client with your Worker URL:
See Cloudflare Worker Deployment Guide for:
records_get_attribute_options tool (#975) - Get valid options for select/status fields with enhanced error messages--option-fetch-delay flagsnake_case, verb-first naming (old names work via aliases until v2.0.0)select_title_to_array for clarityThe server advertises one resource-first catalog. search, fetch, and aaa-health-check are unchanged.
Prior default-catalog names still call the same tool through v2.x. They are not listed in tools/list, they do not change arguments, and MCP_DISABLE_TOOL_ALIASES=true makes them fail. They are removable in v3.0.0. Names that were never that default catalog, including search-records, create-record, and records_search_batch, fail immediately.
The full map is MIGRATION-GUIDE.md and src/constants/tool-names.ts.
The server supports two authentication methods—both use the same Bearer token scheme:
Note: If both are set,
ATTIO_API_KEYtakes precedence.OAuth Users: For detailed setup including PKCE flow and token refresh, see OAuth Authentication Guide.
# 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="[email protected]" # Default owner email address (see below)
export ATTIO_DEFAULT_CURRENCY="USD" # Default currency for deal values

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.
# 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
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.jsonis merged on top ofdefault.json, so only include overrides and additions. Don't duplicate mappings that already exist indefault.json.
The MCP server loads configuration in this order:
default.json - Contains all standard Attio fields (Name, Description, Team, etc.)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:
{
"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"
Add to your Claude Desktop MCP configuration:
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="[email protected]"
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.

# 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:

⚠️ Note: Universal tools documentation is currently being updated to match the latest implementation. Use the API directly or check the source code for the most accurate interface definitions.
📋 Implementation Status: These docs describe the Attio API endpoints. For MCP tool usage, refer to universal tools documentation above.
The shared server uses exact 2.3.1 releases of @modelcontextprotocol/server
and @modelcontextprotocol/core. Types and protocol errors come from the server
package; runtime Zod protocol schemas come from core. The reusable
createServer(context?) factory returns the SDK's low-level Server. The CLI
connects it to StdioServerTransport from @modelcontextprotocol/server/stdio.
This retains the legacy initialize/serve flow; upgrading packages does not
activate protocol revision 2026-07-28.
The v2 client is pinned for tests. The v1 SDK remains a development dependency
for older-client compatibility tests, and the existing Worker transport retains
its optional legacy peer until its transport migration. Neither is a second
runtime owner in the shared server. Domain result schemas, connector content,
and nonretryable uncertain-write results are unchanged. Invalid tool parameters
now receive the SDK's InvalidParams (-32602) protocol error.
After restoring dependencies, build before running the SDK compatibility suite:
bun run build
bun run test:single test/server/sdk-compatibility.test.ts
This suite exercises the built CLI with both SDK client generations, the public library export, and the Worker's built shared-module imports against local HTTP fixtures. After restoring the example's locked development dependencies, also run:
bun run test:sdk:worker
The separate Worker check uses its locked Wrangler/Miniflare toolchain and the
example's 2024-12-01 compatibility date with nodejs_compat. It builds a temporary
bundle and exercises workerd locally: missing/invalid session denial, authorized
legacy initialization/discovery, output schemas, and an uncertain delete sent
exactly once to an intercepted upstream. No credentials or live CRM access are
needed. Neither check certifies modern protocol serving or a production deployment.
See the official v2 migration guide.
