m3-langchain 2026.7.15.1

Recognizable alias for m3-memory's LangChain / LangGraph integration (drop-in Mem0 replacement, M3Store, M3Saver checkpointer, retriever, LCEL). Re-exports m3_memory.langchain.

m3-langchain

A recognizable, databricks-langchain-style alias for m3-memory's LangChain / LangGraph integration. It contains no code of its own — it re-exports m3_memory.langchain and depends on m3-memory[langchain], so pip install m3-langchain gives you the full, local-first m3 memory layer under a discoverable name.

pip install m3-langchain

from m3_langchain import Memory, M3Store, M3Saver
# Memory  → drop-in Mem0 replacement (one-line import swap)
# M3Store → LangGraph BaseStore / backs LangMem
# M3Saver → LangGraph checkpointer (pause / resume / time-travel)

These are the same objects as from m3_memory.langchain import .... New code can import from either path; this package exists for name-discoverability.

Full integration guide, examples, and the complete surface list (retriever, chat history, LCEL MemoryWrite/MemoryRetrieve, the m3-native extras .supersede/as_of=/.forget/.related) live in the main repo: skynetcmd/m3-memory.
