About Black SEO Analyzer

Black SEO Analyzer is an MCP server published by the GitHub account sethblack. Audit a page or crawl a whole site for technical SEO issues, locally. Compares crawls.

It runs on your own machine: your AI client starts it from the MCP bundle package bseoa-26.9.16-win32.mcpb at version 26.9.16.

It asks for one secret: BLACK_SEO_ANALYZER_KEY. Give it a key with the least access that still works.

Version 26.9.16 was published on 7 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.
