codebase-memory-mcpMCP Server40/100 via “persistent sqlite knowledge graph with cypher query engine”
High-performance code intelligence MCP server. Indexes codebases into a persistent knowledge graph — average repo in milliseconds. 66 languages, sub-ms queries, 99% fewer tokens. Single static binary, zero dependencies.
Unique: Implements a Cypher query engine in C within a single static binary, achieving sub-millisecond query latency on graphs with thousands of nodes. Uses content-hash-based incremental indexing to detect file changes and update only affected graph regions, enabling ~4× faster re-indexing than full-scan approaches. Stores graph in SQLite WAL mode for ACID compliance and concurrent read access.
vs others: Delivers sub-millisecond Cypher queries on local graphs without network latency, whereas cloud-based code intelligence services (GitHub Copilot, Tabnine) incur 100-500ms round-trip latency and require sending code to external servers.
