Vestige — a local-first MCP memory server for agents (FSRS decay, active forgetting)

[samvallad33]

Wanted to share a project in case it is useful to people here, since I see a few memory and brain harnesses in this category already.

I built Vestige, a local-first memory server for AI agents that speaks MCP. It runs as a single Rust binary, stores everything in a local SQLite database, and makes no external calls for the core memory functions, so it lines up well with the self-hosted, own-your-data approach a lot of Khoj users care about.

A couple of things that make it different from a plain vector store:

• FSRS-6 spaced-repetition decay, so memories fade on a schedule instead of piling up forever
• active forgetting and prediction-error gating on writes, so it dedupes and reconciles instead of storing everything
• a small 3D dashboard to actually see the memory graph

Install is npm install -g vestige-mcp-server, then point any MCP client at vestige-mcp.

Full disclosure, I am the author, so I am biased. Mostly sharing because the local-first crowd here seems like the right audience, and I would genuinely like feedback from people running self-hosted setups.
