Overview

iai-memory is a local MCP server that gives Claude Code, Codex CLI, Cursor and other MCP hosts a long-term memory. Hooks capture each turn word-for-word, an idle-time daemon embeds, encrypts (AES-256-GCM) and consolidates them, and a small memory pack is injected at session start and on later turns. It exposes 15 MCP tools and a local dashboard via `iai brain`, with no account or API key.

Who it is for: Developers wanting persistent local memory in Claude Code, Codex or Cursor

Strengths

  • Runs locally with encrypted store; no account, API key or telemetry
  • Automatic capture and context injection through host hooks, no manual 'remember' step
  • Reports reproducible benchmarks in bench/, e.g. LongMemEval-S R@5 0.962
  • Contradiction handling closes old records' validity intervals and links the replacement

Weaknesses

  • Ambient behaviour varies by host; OpenClaw and Gemini CLI get MCP tools only
  • Recall is usually mediocre during roughly the first ten sessions
  • Source install needs Python, Node.js 18+ and Rust; Windows support is beta
  • Solo-maintained; default store is English-first and non-English needs a custom embedder

What it needs

  • Needs Python 3.11 or 3.12, Node.js 18+ and Rust (source install only), Claude Code subscription (optional nightly REM step), Hugging Face (one-time embedding model download)
