Overview

agentmemory captures what a coding agent does across sessions, stores it as searchable memory, and injects relevant context at the start of the next session. It runs as a local Node.js server on the pinned iii engine and connects to agents through hooks, MCP, or REST, with 20 adapters listed. Keyless mode uses BM25 search; vector embeddings need a provider or the local Xenova/all-MiniLM-L6-v2 model.

Who it is for: Developers using coding agents who want memory kept across sessions

Strengths

  • No external database; state lives in a local iii engine data directory
  • Works with 20 listed agents through hooks, MCP, or REST
  • Keyless BM25 mode works without any API key
  • Local embeddings via EMBEDDING_PROVIDER=local after a one-time model download

Weaknesses

  • Keyless mode has no vector search, so semantic queries can return nothing
  • Pinned to iii-engine v0.22.1; refuses to attach to other engine versions
  • Native Windows needs manual iii.exe install; WSL2 or Docker recommended
  • Uses four local ports (3111, 3112, 3113, 49134)

What it needs

  • no GPU
  • Docker + Compose
  • Needs Node.js 20+, iii-engine v0.22.1
  • Models: Xenova/all-MiniLM-L6-v2 (local embeddings)
  • port 3113
