# Serpix alternative: Google SERP API MCP

> CrakSEO vs Serpix for SERP data in AI agents: price per search, MCP support, engines and the rest of the SEO toolkit. When to use each.

Serpix is a Google SERP API built for AI applications: send a query, get compact JSON back, billed per successful search from prepaid credits. CrakSEO's [Google SERP API MCP](https://docs.crakseo.com/mcp-servers/serp-api.md) is a remote MCP server rather than a REST API you wire up yourself, and it sits next to keyword, backlink, indexing and Search Console tools.
