Apollo

Connects Claude to Apollo's sales intelligence database of 210M+ contacts and 35M+ companies. Lets you search for leads by job title, company, location, or tech stack, then enrich records with email addresses, phone numbers, funding data, and employment history. Built by MCP Armory using their automated OpenAPI generator, so it covers Apollo's full REST API surface. Useful when you're building prospecting workflows, researching accounts, or need to validate contact information without leaving your chat interface. Authentication uses Apollo's standard API key. Like all Armory servers, this runs locally via stdio and validates requests with Pydantic before hitting the live API.
