RevenueBase MCP: B2B contact search and email checks in your AI app

RevenueBase's MCP server finds B2B contacts, shows how much of a target audience its data covers, enriches emails and verifies deliverability. ContextGate connects it to Claude, ChatGPT and Cursor; since the results are people's contact details, a workspace policy can hide personal data, and Activity records each search.
