# attio-mcp-server This is an MCP server for [Attio](https://attio.com/), the AI-native CRM. It allows mcp clients (like Claude) to connect to the
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverYou will need 2 environment variables: ATTIO_API_KEY, YOUR_ATTIO_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Before you begin, ensure you have the following installed: - Node.js (recommended v22 or higher) - npm - git - dotenv
Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Attio's toolset — Prerequisites — is a fair guide to whether it matches your workflow. It is maintained by hmk; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Attio's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
