MCP (official, remote)
Add this server to your agent's MCP settings, then sign in when asked.
{ "mcpServers": { "attio": { "url": "https://mcp.attio.com/mcp" } } }
Call the MCP tool update-record.
Server URL: https://mcp.attio.com/mcp
API (official)
- Base URL: https://api.attio.com
- Endpoint:
PATCH /v2/objects/{object}/records/{record_id} - Auth: send the header
Authorization: Bearer $ATTIO_API_KEY - Get a key: https://attio.com/help/reference/apps/generating-an-api-key

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.
Rules
- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
