Give an agent access to a Clay function

Use this pattern when you want Claude Code, Codex, or Cursor to call a Clay function for structured GTM data.

​

1. Install the Clay plugin

The Clay plugin gives agents Clay’s skills and the clay CLI.

​

2. Choose a function

Use a Clay-managed function for common jobs like finding emails or enriching companies. Use a custom function when your team already has Clay logic it wants agents to call.

​

3. Expose the function

For custom functions:

1. Open Functions.
2. Select the function.
3. Open Details.
4. Enable API so the plugin CLI can run it.
5. Enable MCP only if a separate MCP client (not the plugin) should call it.

​

4. Let the agent call it

After setup, the agent discovers and runs the function through the plugin’s routines skill. Keep the input schema tight and the output predictable. Good functions for agents:

• Find a person’s work email.
• Enrich a company by domain.
• Score an inbound lead.
• Summarize account research.
• Route a lead to the right owner or motion.
