GreenNode Agent Bridge

A bridge package for connecting multiple agent frameworks (LangGraph, CrewAI, Microsoft Agent Framework, etc.) with GreenNode AgentBase. Use your preferred agent framework while persisting state and memory in AgentBase Memory and Runtime services.

Features

• Framework adaptors – Integrate agent frameworks with GreenNode AgentBase Memory and Runtime.
• Optional extras – Install only the frameworks you use; extras are isolated so installing one does not pull in others.
• LangGraph support – First-class support for LangGraph with:
  • AgentBaseMemoryEvents – A BaseCheckpointSaver that persists LangGraph checkpoints as events in AgentBase Memory.
  • AgentBaseMemoryRecords – A BaseStore that saves chat messages as conversational events and retrieves memories via semantic search (embedding and processing run in AgentBase Memory).

Requirements

• Python 3.10+
• GreenNode AgentBase (core dependency)

Installation

Base package (AgentBase only; no framework adaptors):

pip install greennode-agent-bridge

With LangGraph support:

pip install "greennode-agent-bridge[langgraph]"

Other extras (e.g. CrewAI) may be added in future releases. Installing one extra does not install packages from other extras.

Usage

LangGraph checkpoint and store

When the [langgraph] extra is installed, you can use AgentBase Memory as a checkpoint saver and as a store for conversation and memory:

from greennode_agent_bridge import AgentBaseMemoryEvents, AgentBaseMemoryRecords

# Checkpoint saver for LangGraph (persists graph state to AgentBase Memory)
checkpointer = AgentBaseMemoryEvents(
    memory_id="your-memory-id",
    # optional: memory_client=client,
)

# Store for chat messages and semantic memory (saves events, retrieves via AgentBase)
store = AgentBaseMemoryRecords(
    memory_id="your-memory-id",
)

# Use with your LangGraph graph
# graph = ... .compile(checkpointer=checkpointer)
# app with store for memory operations

Configure memory_id (and optionally credentials/client) according to your AgentBase Memory setup.

Without optional dependencies

If you import LangGraph types without installing the [langgraph] extra, the package raises an error that tells you to install greennode-agent-bridge[langgraph].
