How can the GitHub MCP server access a repository's wiki?

  Closed as not planned. GitHub's REST and GraphQL APIs have no endpoints for reading, searching, or managing wiki pages, so the MCP server's existing tools (including search_code) cannot reach wiki content. The maintainers confirmed this after investigating the possibility.

  The thread does confirm one thing: the wiki is reachable as a Git remote. A commenter ran git ls-remote https://$GH_PUBLIC_REPOS@github.com/robbiemu/aclarai.wiki.git and got HEAD and refs/heads/master, showing the Git transfer protocol works on .wiki.git URLs. However, the maintainers decided against building wiki tools on top of that: supporting read, search, write, synchronization, and conflict handling for a separate Git-backed implementation was too costly relative to their priorities. They said they will reevaluate if native API support becomes available.

  The only workaround described in the thread: keep documentation as Markdown in a regular GitHub repo. One commenter reported that GitHub Copilot chat's #githubRepo tool searches such repos well for AI-searchable internal docs.

  General advice: if you put a PAT in a clone or ls-remote URL, it can leak into shell history and into the stored remote URL of any clone; prefer a credential helper or Git's env-var-based credential handling.

  What @robbiemu tried on GitHub (Didn't work)

  The reporter tried the search_code tool with repo:org/repo.wiki, type:wiki, and type:wikis query forms to find wiki pages; none returned wiki content.

  What @robbiemu tried on GitHub (Worked)

  Tested the Git transfer protocol with git ls-remote https://$GH_PUBLIC_REPOS@github.com/robbiemu/aclarai.wiki.git, which returned the wiki's HEAD and refs/heads/master, proving the wiki is reachable as a Git remote.

  What @Jikodis tried on GitHub (Worked)

  Described an existing setup where docs live as Markdown in a regular GitHub repo and are searched with the #githubRepo tool in GitHub Copilot chat, reporting it works well for AI-searchable internal documentation.
