Run your outreach from Claude or ChatGPT

Q: How do I disconnect it?

In Kerux, open Integrations > Developers > Connected apps and click Disconnect: it stops on its next request. A connection also ends after 90 days.

Q: Does it work with Claude Code or Cursor?

Yes, with a Kerux API key in the Authorization: Bearer header instead of the sign-in. The developer guide, linked under the setup steps, has the exact command.

Q: Are there ready-made prompts?

Yes. Up to 8, such as Why is a contact stuck? and Build a campaign, depending on the permissions you give. In Claude, click + in the message box and open Kerux.

Add the Kerux connector to Claude or ChatGPT, sign in, and ask in plain words: why a lead is stuck, what needs you today, whether a campaign is ready to launch. The assistant works on your real workspace and asks you before it launches or sends.

How it works

Add the connector
A custom connector with the Kerux address.
Sign in and choose
One workspace, read-only unless you tick more.
Today
1. 2 replies to answer
2. 3 stuck: empty company
3. Q4 campaign ready to launch
Ask in plain words
"What needs my attention today?"

An example workflow

Ask "What needs my attention today?": replies to answer and stuck contacts, grouped by campaign and reason.
Ask "Why is Ana stuck?": the reason, since when, the step she waits on and the fix.
Say "Use 'your team' when the company is empty": the assistant applies the fallback after you say yes.
Ask "Is my Q4 campaign ready to launch?": the launch checklist and forecast, without changing anything.
Say "Launch it": Kerux launches only after the checklist passes and you confirm.

Requests to act. Launching, replying and fixing a contact are marked so the assistant asks you first; campaigns are built as drafts.

Set it up

In claude.ai, open Settings > Connectors and click Add custom connector. In ChatGPT, open Settings > Apps & Connectors, turn on developer mode if your plan asks for it, and Create a connector with OAuth as the authentication.
Name it Kerux, paste the server address https://www.usekerux.com/api/mcp and click Connect. A Kerux page opens: sign in.
Pick the workspace and the permissions (seeing your data is ticked for you; changing things stays off until you tick it), then click Allow.

Plan limits: Custom connectors depend on your Claude or ChatGPT plan. In Kerux, the connector is part of Pro, Agency and the free trial.

Questions

Can Claude or ChatGPT launch a campaign or send a message without asking me?

No. Launching, replying, fixing a contact and adding contacts to a running campaign are marked as actions, so the assistant asks you first. Campaigns are built as drafts.

What can't the assistant do?

It can't add webhooks or send contact data to a new address, buy credits, change Twilio or Bluesky credentials, or touch billing, members or API keys. Launching campaigns and sending broadcasts need the Start campaigns and broadcasts for your contacts permission, and it deletes at most 100 contacts a day. It can't search LinkedIn, and LinkedIn limits apply to everything it does.
