How do I configure the SerpApi API key?

You can set the `SERPAPI_API_KEY` environment variable (recommended for MCP hosts) or create a `.env` file (in the current directory or `~/.google-patents-mcp.env`) with the key.

What tool does Google Patents Mcp provide?

It provides a single MCP tool called `search_patents`, which accepts a search query and optional filters (page, number of results, sort, date range, inventor, assignee, country, language, status, type, and scholar flag).

What credentials does it need?

The recorded environment keys are `SERPAPI_API_KEY`, `LOG_LEVEL`. Keep credentials outside committed files and confirm the configuration required by your installed version.
