Overview
FullEnrich MCP uses the Model Context Protocol (MCP) to connect Claude directly to your FullEnrich account.
When enabled in a conversation, Claude can:
Search for contacts
Enrich them with verified emails and phone numbers
Export results to CSV
Authentication is handled via OAuth. You sign in once, and Claude stores the session securely. No API keys or manual configuration are required.
Before You Start
Make sure you have:
A FullEnrich account
A Claude Pro or Max plan (Connectors are not available on the free plan)
Access to Claude via the web or desktop app

Troubleshooting
I don't see the Connectors option
Connectors are available on Claude Pro and Max plans only. Upgrade your plan to access this feature.
The authentication window opened but nothing happens
Close the browser tab after signing in
Return to Claude
The connection should complete automatically
Claude can't find FullEnrich tools
Make sure the connector is toggled on in the + → Connectors menu
The connector must be enabled for each new conversation
Best Practices
Test the connection with "Check my FullEnrich credits" right after setup.
Turn the FullEnrich connector on at the start of each new conversation.
Ask Claude to show you the results before enriching, so you confirm before any credits are used.
For multi-step workflows, install our FullEnrich skills.
