Best for: GTM engineers and ops-minded sellers building automated prospecting systems.

A spreadsheet that runs your prospecting. The most AI-native tool in GTM.
Clay ships a first-party MCP server (clay.com/mcp, a 21-tool GTM server for Claude, ChatGPT, and Codex) on top of an Enterprise-tier REST HTTP API and webhooks, so assistants can drive Clay directly. It is also AI-native in-workflow with built-in Claude and GPT calls per row.
The verdict: If you're serious about AI-driven outbound, Clay is close to essential.
