JustSerpAPI MCP Server

Use JustSerpAPI from Codex, Claude Desktop, Cursor, and other MCP-compatible AI assistants.

This MCP server helps your assistant find the right JustSerpAPI endpoint, inspect the required parameters, call the API, and continue paginated results when the API returns a next-page token or offset.

Quick Start

Remote HTTP

Remote HTTP is the recommended setup.

{
  "mcpServers": {
    "justserpapi": {
      "url": "https://mcp.justserpapi.com/mcp",
      "headers": {
        "Authorization": "Bearer your_api_key"
      }
    }
  }
}

Local stdio

You can also run the MCP server locally with npx.

{
  "mcpServers": {
    "justserpapi": {
      "command": "npx",
      "args": ["-y", "justserpapi-mcp"],
      "env": {
        "JUSTSERPAPI_API_KEY": "your_api_key"
      }
    }
  }
}

Example Prompts

Ask your AI assistant naturally:

Find the Google search API and show me the required parameters.

Search Google for "best running shoes" in the United States.

Find the Google Maps reviews endpoint and tell me how to request the next page.

Get Google Trends trending-now results for the US.

Find the Google Shopping search API and call it for "iphone 16 case".

Convert this web page to Markdown: https://example.com

Continue to the next page of the previous JustSerpAPI result.

Check my remaining JustSerpAPI credits.

Show my API usage for the last 30 days.

The API returned code 402. Explain what it means and what I should check.

Response Format

call_endpoint returns the JustSerpAPI response data as raw JSON. Large arrays and long text fields may be shortened so the AI assistant can read the result reliably. When that happens, the response includes truncated: true and the paths that were shortened.
