google_reviews returns the Google Maps reviews of one place by place_id or
data_id with sorting, topic and text filters and next_page_token
pagination (API key required).

`litescrape-mcp-server --http` serves stateless MCP on POST /mcp with a
/healthz check; each request's API key comes from its Authorization header
or api_key query parameter, so one process serves keyed and keyless
callers. With LITESCRAPE_KEYLESS_PROXY_SECRET set it forwards each caller's
address to the API under that secret, which is how mcp.litescrape.com
meters the free allowance per caller rather than per server.
