Independent review. IonBin has no partnership with Clay and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Spreadsheet-style enrichment that pulls from many data providers and AI research steps (Claygent) to build target lists. Its MCP server lets AI assistants and IDEs run Clay's find-and-enrich tools for a signed-in user.
Clay prices by actions and data credits. Free: 500 actions and 100 data credits a month, up to 200 rows per table, unlimited seats. Launch starts at $167/month billed annually at its default levels, and Growth at $446/month; both scale with the action and credit sliders. Annual billing saves 10%. Checked 2026-10-17. source ↗
How Clay connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Not documented Clay has an official MCP server and Claude (incl. Claude Code) supports MCP, but Clay's docs don't name this pairing. Auth setup may differ.

Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
