@mubit-ai/langgraph

LangGraph.js BaseStore backed by MuBit.

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

Install

npm install @mubit-ai/langgraph @langchain/langgraph @mubit-ai/sdk

Basic usage

import { MubitStore } from "@mubit-ai/langgraph";

const store = new MubitStore({
  endpoint: "http://127.0.0.1:3000",
  apiKey: process.env.MUBIT_API_KEY,
});

await store.put(["memories", "user-1", "session-1"], "deploy-note", {
  text: "Canary before rollout.",
  intent: "lesson",
  source: "human",
});

const results = await store.search(["memories", "user-1"], {
  query: "What rollout lesson do we have?",
  limit: 5,
});

Namespace mapping

| Namespace | MuBit scope | | --- | --- | | ["memories"] | global | | ["memories", userId] | user-scoped | | ["memories", userId, sessionId] | user + session scoped |

Store behavior

• put() writes through MuBit control ingest with upsert_key
• get() and search() use MuBit control query
• evidence metadata is normalized from current MuBit response fields
• listNamespaces() remains local cache based
• delete() remains a no-op because MuBit deletion is explicit and scope-based

MuBit extension methods

Existing MAS helpers:

• checkpoint(namespace, snapshot, options)
• recordOutcome(namespace, referenceId, outcome, options)
• surfaceStrategies(namespace, options)

Current observability and coordination helpers:

• getContext(namespace, options)
• memoryHealth(namespace, options)
• diagnose(namespace, options)
• archive(namespace, options)
• dereference(namespace, options)
• registerAgent(namespace, options)
• listAgents(namespace)
• handoff(namespace, options)
• feedback(namespace, options)

Config

| Option | Default | Purpose | | --- | --- | --- | | endpoint | http://127.0.0.1:3000 | MuBit HTTP endpoint | | apiKey / api_key | "" | MuBit API key |

For tests or advanced embedding, you can inject mubitClient directly.
