Connect Claude & ChatGPT to Leadfox

Ask your AI to look up a contact in Leadfox, add people to a list, or tell you how last month's campaign performed. It can create and update contacts, lists and email designs, change campaign settings and read sends, opens and clicks. Your email marketing gets handled from a chat instead of a dashboard.

Try asking

“Add [email protected] as a contact with company Nordic Foods, or update her if she exists.”
The AI creates the contact by email, or updates the existing one, and sets the company property.
“Put her on the Webinar September list.”
It finds the list and the contact and adds the contact to the list.
“How many contacts are on the Newsletter list?”
It counts the contacts in the list, optionally narrowed by filters you describe.

What your AI can do

Contacts and lists

Search, create, update and upsert contacts, create lists, add or remove contacts and count who is on a list.

Emails and campaigns

Read and create email designs, update subject, sender and content, and change a campaign's lists, emails, start time or status.

Metrics

Read sends, opens, clicks and more for a campaign, a single email variant or the whole account.

“How did the spring campaign perform?”
It reads the campaign's email metrics, such as sends, opens and clicks, for the date range you ask about.
“Draft an email called Product update October with this subject and text.”
It creates the email with name, subject, sender and HTML body. The email is not sent.
“Which custom fields do we have on contacts?”
It lists the contact properties with their shortcodes, so you know which fields you can fill in or use in emails.

Set up in three steps

1
Pick the app
Create a free PipMCP account and choose Leadfox from the app list.
2
Paste your key
Paste your Leadfox API key and secret. In Leadfox, open the API page (https://app.leadfox.co/lf/#/v1/api) and generate an API key and secret if you have none; any domain name works. The secret acts as you with your role's permissions, and generating a new secret revokes the old one. PipMCP uses the pair to get access tokens, so there is no separate sign-in.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Leadfox?

The AI can list, read, create, update and delete contacts, and create or update a contact by email. It can list and create lists, add and remove contacts on them and count list members. It can read and create email designs, read and update campaigns, list mailing lists and contact properties, and read email metrics.

Does the AI see my Leadfox API key and secret?

No. Your Leadfox credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with read-only tools. Activating a campaign can send emails to contacts, and deleting a contact cannot be undone. Both can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Leadfox account.

Can the AI send emails to my contacts?

Creating or editing an email does not send it. Emails go out when a campaign is active, and the AI can only get there by changing a campaign's status with update_campaign. You can switch that tool off or require your approval for it.
