Connect Claude & ChatGPT to lemlist

Ask your AI how your lemlist campaigns are doing, who replied, or to add a new lead to a campaign. It can create, start and pause campaigns, mark leads as interested or not, search lemlist's people and company databases, and find emails and phone numbers. Outreach follow-up happens in the chat instead of across campaign screens.

Questions

What can the AI do in lemlist?

The AI can read campaigns, campaign stats, leads, activities, contacts, companies and contact lists. It can create, start and pause campaigns, add, update, pause and remove leads, mark leads as interested or not interested, save contacts, search lemlist's databases and enrich people.

Does the AI see my lemlist API key?

No. Your lemlist API key is encrypted at rest and never shown to the AI. After you save it, it is 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 stats and lookups only. Starting a campaign sends emails, and removing a lead from a campaign can require your approval before it runs. 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 lemlist account, and enrichment uses your lemlist credits.

Why do I leave the username empty?

lemlist's API signs in with basic authentication where the username is empty and the API key is the password. PipMCP sends it that way for you, so you only paste the key.
