What Apollo.io API endpoints are exposed as tools?

Five tools are available: `people_enrichment`, `organization_enrichment`, `people_search`, `organization_search`, and `organization_job_postings`.

What runtime dependencies are required?

The server requires Python, `uv` (for sync and running), and the packages listed (implicitly from `uv sync`). An Apollo.io API key is mandatory.

How does authentication work?

Authentication is via an Apollo.io API key set as the environment variable `APOLLO_IO_API_KEY` or in a `.env` file in the project root.

Can this server be used with Claude for Desktop?

Yes. It uses the `stdio` transport. A sample configuration is provided in the README for `claude_desktop_config.json`.

Are there any known limitations or data residency considerations?

The README does not mention any limitations or where data is processed. Data is sent to and from the Apollo.io API based on the user's queries.
