Pros & cons
codebase-memory-mcp (DeusData)
Pros: Single-binary zero-deps deployment; 155-language tree-sitter coverage; structural queries replace grep at 120x fewer tokens; SLSA-3 + Sigstore + VirusTotal; team-shared graph artifact format; preprint with reproduction-friendly evaluation.
Cons: Preprint not peer-reviewed; founders/company opaque (DeusData has no disclosed principals); no managed/cloud option; SEMANTICALLY_RELATED edges depend on optional embedding pipeline.
Official MCP Memory server
Pros: Reference implementation in the MCP spec; smallest possible memory primitive — useful for testing and lightweight cases.
Cons: Minimal feature set — no extraction, no governance, no retention policy; production deployments quickly outgrow it.
