Attio
Welcome to agentic revenue.
Attio positions itself as "the CRM for agentic revenue": a CRM built around a real-time data layer ("Universal Context") plus AI agents, workflows, sequences, and call intelligence, aimed at automating prospecting, deal progression, and account growth rather than being a passive system of record.

API & agent surface
From official docs- Authentication
- OAuth 2.0 authorization-code flow (for apps used by multiple workspaces) or a single-workspace API key; both are sent as a Bearer token (Authorization: Bearer <access_token>) and scoped per resource. HTTP Basic Auth (token as username, blank password) is also supported. The MCP server uses OAuth sign-in with an Attio account, no API key.
- Base URL
- https://api.attio.com
- Rate limits
- 100 requests/second for reads and 25 requests/second for writes across the API, per the official rate-limiting guide; List records and List entries also use score-based limits (per-query complexity and a 10-second sliding window). The Query SQL endpoint and query-particle-sql MCP tool are limited to 2 queries per second, and the endpoint has a 30-second execution timeout. Limits may be lowered during incidents or for data-heavy endpoints.
- Notable endpoints
- Search records (POST /v2/objects/records/search)
- List/Create/Upsert/Get/Update/Delete records, plus Merge two records (POST /v2/objects/{object}/records/merge)
- Lists and list entries, including Upsert a list entry by parent
- Webhooks: create, list, get, update, delete
- Meetings and call recordings (the standalone Get call transcript endpoint is marked deprecated)
- Notes, tasks, comments and threads, files, and emails (the email scope exposes metadata only)
- Query SQL (POST /v2/sql, Enterprise plan only)
- Identify (GET /v2/self)
- MCP tools exposed

What is Attio
Vendor's own claimAttio is a CRM platform that markets itself around AI agents operating directly on live workspace data rather than around static record-keeping, and says it is trusted by 30,000+ customers. It exposes that data model through a REST API (OpenAPI 3.1, v2.0.0), an App SDK for building embedded apps and workflow blocks, a hosted MCP server for AI-assistant access, and a read-only SQL interface (Enterprise only) reachable through a REST endpoint, an MCP tool, and PostgreSQL-protocol data connectors.
Ideal customer profile
Vendor's own claimSales organizations that want a CRM built around automation from day one: startups automating their GTM motion with a lean team, and mid-market/enterprise revenue teams running complex, multi-stage deal pipelines who want AI agents doing research, scoring, and routing work rather than reps doing it manually.
Who should look elsewhere
Our readThe Free plan caps at 3 seats, 3 objects, and 50,000 records, and Call Intelligence, sequences, advanced access permissions, record templates, and formula attributes only unlock on Pro ($99 per user per month billed monthly, $79 billed annually). Single sign-on, SCIM, CSV export limits, and the read-only SQL interface are Enterprise-only, so teams that need SSO or want to run BI queries directly against CRM data need the custom-priced top plan. Customer data is hosted on Google Cloud Platform in the EU, and Attio says it does not offer other data residency options. Teams that want a CRM as a passive system of record with minimal AI involvement are working against Attio's stated product direction rather than with it.
