# Add managed long-term memory to LangGraph agents with LangMem

Give LangGraph agents memory management and search tools so they can store, retrieve, and update durable facts across sessions.

## Prerequisites

Python, langmem, LangGraph or LangChain agent runtime, persistent store such as Postgres for production, LLM provider API key

## Installation

Use the upstream install or setup path that matches your environment:
- pip install -U langmem

Requirements and caveats from upstream:
- python

Basic usage or getting-started notes:
- Configure your environment with an API key for your favorite LLM provider:
- export ANTHROPIC_API_KEY="sk-..." # Or another supported LLM provider
- Here's how to create an agent that actively manages its own long-term memory in just a few lines:

- Extracted from upstream docs: https://raw.githubusercontent.com/langchain-ai/langmem/HEAD/README.md
