PyPI License: MIT

LangGraph integration for GoodMem — long-term agent memory with semantic storage and retrieval.

GoodMem is a memory layer for AI agents that handles embedding, vector search, reranking, and LLM-powered answering server-side. This package exposes GoodMem operations as LangGraph tools that can be used with any LangGraph agent or graph.

Installation

pip install langgraph-goodmem

Requires Python 3.10+.

Quick start

from langgraph_goodmem import (
    GoodMemCreateSpace,
    GoodMemCreateMemory,
    GoodMemRetrieveMemories,
)
from langgraph.prebuilt import create_react_agent

goodmem_kwargs = {
    "goodmem_base_url": "http://localhost:8080",
    "goodmem_api_key": "your-api-key",
}

tools = [
    GoodMemCreateSpace(**goodmem_kwargs),
    GoodMemCreateMemory(**goodmem_kwargs),
    GoodMemRetrieveMemories(**goodmem_kwargs),
]

agent = create_react_agent(model="gpt-4o", tools=tools)

Usage in a custom LangGraph graph

from langgraph.graph import StateGraph, START, END
from langgraph.prebuilt import ToolNode
from langgraph_goodmem import (
    GoodMemCreateSpace,
    GoodMemCreateMemory,
    GoodMemRetrieveMemories,
)

tools = [
    GoodMemCreateSpace(**goodmem_kwargs),
    GoodMemCreateMemory(**goodmem_kwargs),
    GoodMemRetrieveMemories(**goodmem_kwargs),
]

tool_node = ToolNode(tools)

Environment variables

Variable Description
GOODMEM_BASE_URL Base URL of the GoodMem API server
GOODMEM_API_KEY API key for authentication
GOODMEM_VERIFY_SSL Set to false to skip TLS verification for self-signed certs (default: true)
