Knowing

A content-addressed code graph that treats relationships as cryptographically verifiable facts. The 28 MCP tools cover ranked context retrieval (context_for_task packs symbols to your token budget using graph centrality and 263 framework equivalence classes), blast radius analysis across callers and tests, and Merkle proof generation for audit trails. Built for agents that need precision over grep, with implicit feedback that demotes unused symbols and auto-expires when code changes. The CLI supports snapshot chains tied to git commits, supply chain scanning for credential access patterns, and offline proof verification. Install via brew, npm, pip, or go, point it at a repo, and the MCP server auto-indexes on launch. No API keys, no model downloads, gets smarter with use.
