Seven MCP tools that treat your codebase as a knowledge graph instead of flat files. You get `scan_repository` to build the graph, `query_graph` to ask architectural questions, `analyze_impact` before changes, and `teach_lesson` to persist rules the system remembers across sessions. The substrate powers both dev-time reasoning (cross-file refactor analysis, dependency checks) and runtime governance with cryptographic receipts anchored to Sigstore Rekor. Runs local-first with 14 LLM backend options including Ollama. Useful when you need AI that understands how modules connect, not just what individual files contain, or when you're shipping regulated AI and need third-party-verifiable decision logs that survive infrastructure changes.
