Introduction

VibeSell finds B2B prospects and runs cold email campaigns for founders: it defines your target, sources the leads, sets up the sending domains and mailboxes, warms them up and sends your sequence.

The VibeSell MCP server puts that same workspace in your AI assistant. Connected to Claude, Claude Code, Codex or any client that speaks the Model Context Protocol, your assistant can read where your workspace stands, count and preview leads, save your offer and your target, size your sending, write your sequence with you and prepare your campaign — with 38 tools that do exactly what the VibeSell app does.

What it is

• A remote MCP server at https://api.vibesell.it/v1/mcp, over Streamable HTTP. There is nothing to install.
• Your VibeSell account, reached through OAuth 2.1: you sign in on VibeSell’s own consent page and choose to allow the app. The assistant never sees your password.
• The same workspace as the app. What the assistant saves shows up in VibeSell, and what you do in VibeSell is what the assistant reads. The MCP never writes in your VibeSell chat thread.
• Interactive cards in Claude. In the Claude app, every tool result renders as a VibeSell card — leads, plans, domains, the campaign — with Approve and Reject buttons on approval cards. Text-only clients get the same data as Markdown and JSON.

What it will never do on its own

The human click

Nothing that spends money, imports leads, sends emails or cannot be undone runs on the model’s word. Those tools only open an approval card; the action runs when you click Approve — on the card in Claude, or in the VibeSell app.

• Spend lead credits or buy domains. import_leads and order_sending_setup prepare a card.
• Launch, stop or resume a campaign. launch_campaign, stop_campaign and resume_campaign prepare a card.
• Pay for a plan. start_checkout returns a Stripe link; you open it and pay yourself. upgrade_plan prepares a card.
• Say yes for you. Confirming your target, your sizing or your sequence records the sentence you wrote, quoted in theirWords.

Who it is for

• Founders who live in Claude or Codex and want to run their outbound from there: describe the target in a sentence, look at the leads, decide, and let VibeSell do the setup.
• Teams building on VibeSell, who want to know exactly which tools exist, what they take and what they return — the tool reference and the protocol reference are generated from the server’s own catalog.
