FAQ from Apollo.io MCP Server

What exactly does Apollo.io MCP Server do?

It exposes five tools—people enrichment, organization enrichment, people search, organization search, and organization job postings—that let AI assistants read and query Apollo.io data.

How do I authenticate with the Apollo.io API?

Generate an API key in your Apollo.io account under Settings > API, then provide it either as the APOLLO_IO_API_KEY environment variable or as the --api-key command-line argument.

What runtime or dependencies are required?

The server is built with TypeScript (4.9.5) and the MCP SDK (1.8.0). You need Node.js and npm installed to clone, install dependencies, and build the project.

Can I run it as an SSE server with authentication?

Yes. Use the mcp-proxy-auth package by setting AUTH_SERVER_URL to your verification endpoint and running npx mcp-proxy-auth node dist/index.js. The SSE endpoint is then available at localhost:8080/sse?apiKey=apikey.

How is this server different from using the Apollo.io API directly?

It translates natural language commands from AI assistants into structured Apollo.io API calls, removing the need to manually construct HTTP requests or handle authentication inside the assistant.
