vestige

Vestige gives AI agents sharp memory: a local-first Rust MCP server that reaches backward through time to find the quiet change, decision, or service that caused today’s failure, not the lookalike. Maintained by samvallad33 on GitHub, where it has earned 584 stars from the community.

It's actively developed around ai-memory, claude, cognitive-science, and is a solid reference for anyone building with these tools.
