There is one at the root https://nextjs.org/docs/llms.txt which links to the rest. Having said that I think those llms.txt files are a trap as they poison the context way too quickly.

I haven't looked into MCPs for Next.js yet. Maybe there is one available as it would likely be a better solution long-term.

I would suggest you to use context7's mcp instead

I get 404 pages attempting to open the .md links, some randomly from the bottom of the list. Is there a github repo equivalent of the all the .md files to find and "replace"?
