momex 0.2.0

Memory system for AI agents with Structured RAG, built on TypeAgent

Fork Changes

I've been keeping an eye on this repo for a while. I'm also personally interested in personal assistant agents, and I've been trying to find best practices for memory. Structured RAG is a great design, but since this is an experimental project, the feature set isn't complete yet. So I forked the original repo and added more features, aiming to make it work for more general use cases and projects.

This fork adds Momex - a high-level API wrapper for TypeAgent's Structured RAG.

What's New

• Agent API - High-level chat interface with automatic memory management
• Short-term memory - Session-based conversation history with persistence
• Long-term memory - Structured RAG with entity/action/topic extraction
• Multi-tenant support with hierarchical collections (user:xiaoyuzhang)
• PostgreSQL backend with pgvector for production deployment

Installation

pip install momex

Quick Start

import asyncio
from momex import Agent, MomexConfig, LLMConfig

async def main():
    config = MomexConfig(
        llm=LLMConfig(
            provider="openai",
            model="gpt-4o",
            api_key="sk-xxx",
        ),
    )

    agent = Agent("user:xiaoyuzhang", config)

    r = await agent.chat("My name is Xiaoyu, I love Python")
    print(r.content)

    r = await agent.chat("What's my name?")
    print(r.content)  # "Your name is Xiaoyu"

asyncio.run(main())

Two API Levels

Level	API	Description
Level 1	Agent	Chat API with automatic memory (recommended)
Level 2	Memory	Manual control for custom agents

See docs/momex.md for full documentation.

Python package 'typeagent'

This is an experimental prototype

Working toward a shared understanding of the MVP for structured RAG.

This is sample code

This is an in-progress project aiming at a Pythonic translation of TypeAgent KnowPro and a few related packages from TypeScript to Python.

Warning

This library will send its input to an LLM hosted by a third party. Don't use it to index confidential information.
