MCP support

Some SeoTools checkers are available on a trial basis as an MCP server, so an AI assistant can call them directly.

MCP (Model Context Protocol) is a standard that lets AI assistants call external tools directly. This endpoint exposes 8 of SeoTools' checkers as MCP tools so an AI client can run them for you.

Currently offered on a trial basis; the endpoint or tool set may change without notice.
No authentication required (authless).
Free to use, but subject to the same per-tool rate limits as the web version (see each tool's page).
