DeusData has released an open-source MCP server for code repositories that builds a persistent graph AI coding agents can query across 162 programming languages.
The codebase-memory-mcp project runs indexing and querying locally, without an embedded LLM or a required API key. Instead of repeatedly scanning raw files, agents can query repository structure such as functions, classes, call chains, HTTP routes, data flows, and cross-service links. A background watcher can also refresh the index as code changes.
For builders, the draw is persistent repo context without sending source code to a hosted model by default. That could make it useful for code assistants working across large repositories where repeated file-by-file exploration is slow or costly.
DeusData says the project is MIT-licensed and offers native builds for macOS, Linux, and Windows. The company also claims roughly 120x lower token use across five structural queries, but that result is still a vendor benchmark rather than an independently reproduced one.
