What stays under your control
Read-only by default
Every change permission stays off until you tick it.
Verified app
Kerux names Claude and ChatGPT on the sign-in page. Any other app gets a warning.
One workspace
The assistant works only in the workspace you pick.
90 days
A connection ends after 90 days. Disconnect it any time in Connected apps.
No new destinations
It can't add webhooks or send contact data to a new address.
No purchases or credentials
It can't buy credits, or change Twilio or Bluesky credentials.
Launches need permission
Starting campaigns and broadcasts needs the Start campaigns and broadcasts for your contacts permission.
100 deletes a day
A connected app deletes at most 100 contacts a day. Delete more in Kerux.
Claude Code, Cursor and other MCP clients
Connect with a Kerux API key instead of the sign-in.
- Start your free trial and open Integrations > Developers in your workspace.
- Create an API key with only the permissions the assistant needs (read-only is a good start).
- In Claude Code, Cursor or Claude Desktop, add a custom MCP server (HTTP) with the address above and the header Authorization: Bearer followed by your key.
The assistant can't search LinkedIn, and revoking the key disconnects it at once.
