Hunter

Hunter integrates with <a href="https://claude.ai/" rel="nofollow noopener noreferrer" target="_blank">Claude</a> through the Model Context Protocol (MCP), letting you search for email addresses, find leads, and run domain searches using natural language, without leaving your Claude session.

This article walks you through connecting Hunter to Claude, whether you're using the Claude web or desktop app.

___________________________________________________________

This is the easiest way to connect Hunter to Claude. It works in both the <a href="https://claude.ai/" rel="nofollow noopener noreferrer" target="_blank">Claude web app</a> and the Claude desktop app.

💡 On Claude Team and Enterprise plans, only workspace Owners can add custom connectors. If you're a member on one of these plans and don't see the option, use <a href="#h_784c82c11b">Method 2</a> instead.

Open Claude, click "Customize" in the left sidebar, then select "Connectors".

- Name: <code>Hunter</code>
- Remote MCP server URL: <code>https://mcp.hunter.io/mcp</code>

Click "Add", then "Connect".

A Hunter login window will open — log in and authorize access.

1. Open Claude, click "Customize" in the left sidebar, then select "Connectors".
2. Click "Add custom connector".
 
 
 
3. Fill in the following:
 - Name: <code>Hunter</code>
 - Remote MCP server URL: <code>https://mcp.hunter.io/mcp</code>
 
 
 
4. Click "Add", then "Connect".
5. A Hunter login window will open — log in and authorize access.

Once connected, start a new chat. You can ask Claude things like: "Use Hunter to find the email pattern for stripe.com" and it will respond using your Hunter account.

Method 2: Configuration file (Claude Desktop)

Use this method if you're a non-Owner member on a Claude Team or Enterprise plan, or if you prefer to authenticate with your API key directly.

Open Claude Desktop and go to Settings → "Developer" → "Edit Config".

This opens your <code>claude_desktop_config.json</code> file. Add the following inside <code>mcpServers</code>: ​

{ "mcpServers": { "hunter-remote-mcp": { "command": "npx", "args": [ "mcp-remote", "https://mcp.hunter.io/mcp", "--header", "X-API-KEY:YOUR_HUNTER_API_KEY" ] } } }

Replace <code>YOUR_HUNTER_API_KEY</code> with your key from your <a href="https://hunter.io/api-keys" rel="nofollow noopener noreferrer" target="_blank">Hunter dashboard</a>.

Save the file and fully restart Claude Desktop.

1. Open Claude Desktop and go to Settings → "Developer" → "Edit Config".
2. This opens your <code>claude_desktop_config.json</code> file. Add the following inside <code>mcpServers</code>: ​
 { "mcpServers": { "hunter-remote-mcp": { "command": "npx", "args": [ "mcp-remote", "https://mcp.hunter.io/mcp", "--header", "X-API-KEY:YOUR_HUNTER_API_KEY" ] } } }
 
3. Replace <code>YOUR_HUNTER_API_KEY</code> with your key from your <a href="https://hunter.io/api-keys" rel="nofollow noopener noreferrer" target="_blank">Hunter dashboard</a>.
4. Save the file and fully restart Claude Desktop.

💡 This method passes your API key directly in the request headers. It requires <a href="https://nodejs.org/" rel="nofollow noopener noreferrer" target="_blank">Node.js</a> to be installed on your machine, since it uses <code>npx</code> to run <code>mcp-remote</code>.

Start a new chat and ask: "Use Hunter to find the email pattern for stripe.com."

If Hunter returns results, you're all set.

If Hunter isn't responding in Claude after connecting, check the following:

Make sure you started a new chat after connecting — MCP connections aren't picked up mid-conversation.

If you used Method 2, confirm you fully restarted Claude Desktop (quit and reopen, don't just close the window).

Double-check that your API key is correct and active in your <a href="https://hunter.io/api-keys" rel="nofollow noopener noreferrer" target="_blank">Hunter dashboard</a>.

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
