Understand Quickly

A public registry that serves pre-built code knowledge graphs to AI agents over HTTPS. Instead of parsing repositories on every request, agents fetch validated JSON graphs from a central index. The MCP exposes three tools: list_repos returns the catalog, get_graph fetches a specific graph by URL, and search_concepts filters entries by topic or format. Supports multiple graph formats including Understand-Anything, GitNexus, and generic bundle schemas. The registry validates every entry against JSON schemas and syncs nightly to catch stale links. Useful when you want LLMs to operate on structured codebase metadata without running indexers locally. Graphs stay in source repos; the registry only holds pointers, so there's no vendor lock-in or hosting cost.
