One line
Install
claude mcp add serpens --env SERPENS_API_KEY=your-key -- npx -y serpens-mcpClaude Desktop, Cursor, Windsurf and Zed take the same command / args / env shape in their own config files.

Tools
| Tool | What it returns |
|---|---|
google_search | Organic results, plus sitelinks, People Also Ask and related searches where Google renders them |
google_ai_overview | Google's AI Overview with its citations, alongside the organic results |
Output is Markdown by default, because that is what a model reads best. Pass format: "json" when you want to parse it instead.
Supply chain
Zero dependencies
One file of protocol, one HTTP client, nothing else. npx starts it in under a second, and there is no third-party code between your agent and the API — which, for a package that holds your key, is the whole argument.
Get a key and wire it up
Free tier, no card. The MCP server and the REST API bill from the same allowance.
