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.
