mubit-langgraph

LangGraph BaseStore backed by MuBit.

This adapter now uses the canonical Python SDK transport internally instead of raw httpx, while preserving the LangGraph store interface and adding MuBit-specific helpers for MAS and long-running coding-agent loops.

Install

pip install mubit-langgraph[langgraph]

Basic usage

from mubit_langgraph import MubitStore

store = MubitStore(
    endpoint="http://127.0.0.1:3000",
    api_key="mbt_...",
)

store.batch(
    [
        PutOp(
            namespace=("memories", "user-1", "session-1"),
            key="deploy-note",
            value={"text": "Canary before rollout.", "intent": "lesson"},
        )
    ]
)

Namespace mapping

Store behavior

• PutOp writes through MuBit control ingest with upsert_key
• GetOp and SearchOp use MuBit control query
• evidence metadata is normalized from current MuBit response fields
• namespace listing remains local-cache based
• single-item delete remains a no-op because MuBit deletion is explicit and scope-based

MuBit extension methods

Existing MAS helpers:

• checkpoint()
• record_outcome()
• surface_strategies()

Current observability and coordination helpers:

• get_context()
• memory_health()
• diagnose()
• archive()
• dereference()
• register_agent()
• list_agents()
• handoff()
• feedback()

Config

For tests or custom embedding, you can inject mubit_client directly.
