A Visible and Auditable Agent Memory Layer
techtheist_ggl · reddit · 2026-07-12
This post introduces **Engram**: a new memory MCP focused on making agent memory visible, editable, and auditable. ### The Problem Many memory layers silently write incorrect, outdated, or contradictory information. Over time, retrieval results get polluted, and the agent becomes untrustworthy. ### Key Design - Memories are displayed as a graph viewable in a local browser panel - Can also be embedded in VS Code and JetBrains - Nodes support manual editing, with deletion rights restricted to the user - Supports typed relationships, e.g., `replaces`, `conflicts-with` - Provides local scanning to find similar memories and lets humans or AI determine relationships - Introduces trust decay: long-unused memories are flagged as stale - Every change has an audit log to track "who wrote what and when" ### Tech & Deployment - Rust backend, single lightweight binary - A single SQLite file stored in the repository - RAG uses hybrid retrieval: FTS5 + local vector search (fastembed / ONNX) - Embeddings computed locally, no cloud or API key required - Supports offline operation - Shares the same memory across Claude Code, Codex, Gemini CLI, OpenCode, Kilo, Google Antigravity, etc., via MCP The author mentions the project is being "dogfooded" and welcomes feedback on how to make agent memory trustworthy enough.
