Provide an Apollo.io API token via the APOLLO_IO_API_KEY environment variable or a --api-key command-line argument. Start the server with npm start.

Frequently asked questions

1

What are the runtime requirements for this server?

Node.js and TypeScript. You also need a valid Apollo.io API access token from your Apollo.io account settings.

2

How do I provide the API key?

Set the `APOLLO_IO_API_KEY` environment variable or pass it as a command‑line argument: `npm start -- --api-key=your-api-key`.

3

How is authentication handled in the SSE server?

The SSE server uses the `mcp-proxy-auth` package, which acts as a proxy that verifies API keys against your authentication server. Requests must include an `apiKey` query parameter in the SSE URL.

4

What tools are exposed by the server?

Five tools: `people_enrichment`, `organization_enrichment`, `people_search`, `organization_search`, and `organization_job_postings`. Each accepts specific optional parameters (e.g., first_name, domain, organization_name).

5

Can I add more Apollo.io API endpoints?

Yes. Add new methods to the `ApolloClient` class in `src/apollo-client.ts`, register new tools in the `setupToolHandlers` method in `src/index.ts`, and rebuild with `npm run build`.
