README
Handled Personalizer MCP Server
Generate AI-written personalized cold email opening lines from inside Claude or any MCP-compatible client.
What it does
Two tools exposed over the Model Context Protocol:
personalizer_preview — Free. Personalize up to 3 prospects, no payment required. Returns lines directly in the chat.
personalizer_batch — Paid. Personalize up to 500 prospects. Returns a Stripe checkout link. After payment, results are downloadable as CSV.
Each line is under 20 words and references something specific about the prospect's actual business — fetched from their real website — not generic filler.

| Up to 200 | $29 |
| Up to 500 | $59 |
No subscription. No account needed.
