What it does
MemSearch is Zilliz’s search-over-memory layer for coding agents. Official GitHub description: “A persistent, unified memory layer for all your AI agents (e.g. Claude Code, Codex, DSH), backed by Markdown and Milvus.” Docs: install a plugin and the agent remembers prior work across sessions — conversations are captured, indexed with hybrid search, and recalled when needed.
Markdown under .memsearch/memory/ is the source of truth. Milvus is a derived, rebuildable index (dense + BM25 + RRF). Recall is progressive: search summaries, expand a section, then drill into the original transcript. The same collection-naming algorithm lets Claude Code, Codex, DeepSeek Harness, OpenClaw, and OpenCode share one project memory.
Official positioning is retrieval over agent memory, not a general fact-extraction memory OS. That is the distinction versus Mem0, Zep, and Memoria.
Agent-facing interfaces
- Interaction pattern: CLI + platform plugins
- Catalog protocols: Agent Skill, MCP, CLI, API
- MCP: ⚠️ Not the primary published interface.
- Agent Skill: ✅ Available as platform skills / SKILL.md recall (not npx skills add).
- Onboarding type:
cli
How agents onboard
Interaction pattern: CLI + platform plugins
# CLI / library (ONNX embeddings, no API key)
uv tool install "memsearch[onnx]"
memsearch index ./memory/
memsearch search "how to configure Redis?" --top-k 5
