Manage contacts, companies, deals, tasks, notes and workflows.\n\nThe current version, v1.7.0, was published to the official MCP registry on 2026-08-25. It is distributed as attio-mcp on npm, filed under CRM & Sales by this index, and declares 4 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context.\n\n## Using Attio MCP Server in Claude, Cursor, Gemini CLI, Cline, or Zed?\n\nMCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that).\n\nRewrites your MCP host config so each server launches behind the gate.

A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.\n\nOwn this server? [Screen its description →](/screen)\n\n## That verdict was true at screening time (snapshot 2026-08-25).\n\nContracts can change after screening, with no version bump. The gate pins Attio MCP Server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.\n\n[See your first HOLD in 2 minutes →](/guides/install-the-gate-first-hold)\n\nRelated: [how to trust an MCP server](/guides/how-to-trust-an-mcp-server) · [screen before install](/guides/screen-mcp-server-before-install) · [silent contract drift](/guides/mcp-silent-contract-drift)\n\nPeople vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.\n\n```\n[Independent trust record for Attio MCP Server](https://mcpindex.ai/server/io-github-kesslerio-attio-mcp-server) - screening verdict, registry provenance, and contract drift monitoring.\nIndependent trust record for Attio MCP Server - screening verdict, registry provenance, and contract drift monitoring.\n```\n\nA live verdict badge for your README or listing.
