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


Step-By-Step Setup

Step 1: Open Claude Settings

  • Go to claude.ai and log in

  • Click your profile icon in the bottom-left corner

  • Select Customize

Step 2: Go to Connectors

  • In the Customize panel, click Connectors in the left sidebar

Step 3: Add a custom connector

  • Scroll to the bottom of the page

  • Click Add a custom connector


Step 4: Configure the connector

Enter the following details:

Leave Advanced settings collapsed and empty.

  • Click Add

Tip: FullEnrich handles OAuth authentication automatically. No API keys or tokens are required.

Step 5: Authenticate with FullEnrich

  • A browser window will open automatically

  • Sign in with your FullEnrich account

  • Authorize access

  • Once you see the confirmation message, close the tab and return to Claude

Step 6: Enable the connector in a conversation

  • Open a new chat in Claude

  • Click the + button in the chat input

  • Click Connectors

  • Toggle FullEnrich on


Step 7: Test the connection

Type the following in the chat:

Check my FullEnrich credits

If Claude returns your credit balance, the setup is complete.


For Team and Enterprise Plans

An Owner must first add the connector at the organization level:

Once added, each team member must:

  • Go to Customize → Connectors

  • Click Connect next to FullEnrich

  • Authenticate individually


What You Can do Next

Once connected, you can:

  • Search contacts by role, company, industry, or location

  • Enrich contacts with professional emails or phone numbers

  • Export contacts or companies to CSV

For the full list of tools, see the FullEnrich MCP Server article.


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
