codebase-memory-mcpMCP Server40/100 via “incremental reindexing with content-hash change detection”
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: Uses content-hash-based change detection (SHA-256 comparison) instead of filesystem watchers or timestamps, enabling reliable detection of actual code changes without false positives from build artifacts or temporary files. Adaptive polling intervals (5-60s) balance freshness with CPU overhead. Achieves ~4× faster reindexing than full-scan approaches by re-parsing only modified files.
vs others: Content-hash detection is more reliable than filesystem timestamps (which can be unreliable across network mounts) and more efficient than full-codebase re-parsing, whereas LSP-based approaches require per-language server integration and may miss cross-language dependencies.
