Clay MCP server

What your assistant can do with it

• Search contacts and companies in Clay's data
• Add data points to a contact or company: email, phone, custom Claygent research
• Run the enrichment functions your team configured in Clay
• Read the context of a running enrichment task

How to connect it

1. In Clay, open MCP in the left navigation and check the credit limit set for MCP users.
2. Add the Clay connector in Claude and sign in with your Clay account.
3. Test with a free contact search before any enrichment.
4. Raise the per-user limit for the people who will enrich at volume.

How we use it

We ran it in production from July to October 2026: Claude searched contacts and companies, then enriched the shortlist with emails and Claygent research, without opening a Clay table. We have since moved that work to our own stack, so this page describes a server we ran, not one we run today.

Where it breaks

• Each MCP user has a monthly credit limit, separate from the workspace balance. Ours was 1,000 credits and we hit it on 30/07/2026.
• Once the limit is reached, email enrichment returns no result every time and Claygent data points fail, while the credit balance does not move. It looks exactly like an outage; we lost a day to it.
• Search keeps working past the limit, which makes the block harder to spot.
• The limit resets on the first of the month at 00:00 UTC. An admin can raise it, or reset a user's spend to zero, from the MCP page in Clay's left navigation, not from Settings.

Our take. Useful if your team already lives in Clay and wants its enrichment from a chat. Set the per-user limit before the first big run, and when enrichment suddenly returns nothing, check the MCP usage page before you debug anything else.
