Everything an AI agent needs to use FOSSHunter data, by design.

The catalog is machine-readable end to end: discovery documents, a public JSON API, an OpenAPI contract, MCP tools, and per-tool markdown exports — all read-only, rate limited, and citation-first.

Discovery

llms.txt and the full rulebook

Start with the concise discovery document; open the full rulebook for interpretation rules, the field dictionary, and the response contract before quoting metrics.

Exports

Markdown and JSON for every tool

Fetch citation-ready markdown or canonical JSON for any published tool, or the whole catalog as one markdown index. Responses carry ETags, canonical Link headers, and cache windows.

Citation policy

Cite what you quote, including when it was observed

Repository metrics are point-in-time GitHub observations. When presenting FOSSHunter data, link the tool's canonical_url and include synced_at plus the catalog revision with any metric you quote. Abstain when a comparison returns insufficient_data.
