Summary

The detail dial is the whole trick.

Pulling an entire repository into a context window is usually the wrong move; asking for the structure first and then the files that matter is the right one, and this makes that a parameter rather than a manual step. Caching keyed on the resolved commit SHA means a repeat request for an unchanged repository is free and a request after a push is not stale — which is the correct behaviour and rarer than it sounds. Only the root `.gitignore` is evaluated; nested ones are not, and the project says so.

What it is

A stateless converter from a GitHub URL to Markdown a model can read. It downloads the repository zipball, filters out the noise, and formats what is left — with a detail dial so you can take a directory tree when that is all you need instead of the entire source.

What you get

A repository converted to Markdown from a GitHub URL or an `owner/repo` shorthand, at a chosen level of detail — `ingest_repo`
Four detail levels: `summary` for front-matter with repo name, ref, file count and total size; `structure` for that plus a directory tree; `file-list` for a table of every included file with byte size and line count; and `full` for the complete file contents in fenced code blocks, streamed
Aggressive default filtering: lock files, minified bundles, build and dependency directories, binaries by extension, and any file with null bytes in its first 8 KB
The repository's root `.gitignore` honoured, including wildcards, directory patterns, rooted patterns and negations
Response headers carrying the resolved commit SHA, file count, total size, whether output was truncated and the remaining GitHub rate limit

Requirements

No account needed for the hosted service — point any MCP client at `https://gitprism.cloudemo.org/mcp`. Without a token you get 30 requests per minute per IP; passing your own GitHub personal access token as `github_token` on the call switches you to your own quota of 5,000 requests per hour. The token needs only contents read-only on public repositories. Self-hosting is a Cloudflare Worker: `npm install`, `npm run build`, `npx wrangler secret put GITHUB_TOKEN`, `npx wrangler deploy`. Limits are configurable — 50 MB maximum archive, 10 MB maximum output, 5,000 files — and results are cached for 24 hours keyed on the resolved commit SHA.
