memory-happens: open-source MCP beta for recall over notes, session logs and Git history
terra-viii · reddit · 2026-09-28
memory-happens (MIT-licensed, technical beta) is an MCP tool that adds recall over material you already have: notes, supported session logs, project memory and Git history — with no model or vector database needed for plain search/read.
Key points:
- Demo recipe: a history → selection flow locates the commit removing a lookup cache, revealing the cache key omitted the row revision. The author stresses this is plumbing illustration, not evidence of beating git/grep.
- MCP surface is two generic tools: discover operations and run a recipe. Source, selector and reducer plugins compose in one call; intermediate records need not pass through the calling model; the caller sets the output character budget. Literal and trigram selectors included; model-based reduction optional.
- Known limits: matching can miss things, large recipes hold batches in memory, and general retrieval quality/time savings are unverified.
- No-install recorded demo plus BOOTSTRAP/CONNECT docs; author solicits concrete usage feedback.
