# Kairon

> Find who to write to, when, and what to say. Over LinkedIn and email, from Claude, ChatGPT or the Kairon agent.

Kairon is an MCP server. The operator connects it to an agent they already
use (Claude, ChatGPT, Cursor, or their own) and that agent gains the ability
to search for accounts, qualify them against an ideal customer profile,
enrich the people behind them, and run LinkedIn sequences from the
operator’s own seat.
Nothing is sent without approval unless the operator grants a campaign
autonomy. LinkedIn is live today; email and WhatsApp are being built.
