Use the published `attio-mcp` package with Node.js 20 or newer. The supplied material identifies the package and runtime requirement but does not include complete installation commands or configuration values, so consult the repository documentation for the exact setup procedure.
Yes. The server provides scoped `create_company`, `update_company`, `create_deal`, and `update_deal` tools, along with universal record operations. Deal handling includes field mapping and stage validation, and deal creation can use configurable defaults for stage, owner, and currency.
Yes, through the documented self-hosted Cloudflare Worker deployment for ChatGPT Developer Mode. That path includes OAuth and approval behavior for reads and writes. The README says Smithery is temporarily unavailable for this use case.
