MemVault

MemVault: Long-Term Memory Server
MemVault provides a production-grade API designed to equip AI agents with long-term memory capabilities without the complexities of traditional setups. By abstracting the Retrieval-Augmented Generation (RAG) pipeline into a single API endpoint, it eliminates the need for extensive configurations involving Pinecone, embedding pipelines, and chunking logic, allowing for a seamless development experience on your own infrastructure using PostgreSQL and pgvector.

✨ Key Features

• Hybrid Search: Efficiently retrieves memories by assessing a weighted score based on Semantic Similarity, Recency, and Importance.
• Auto-Embedding: Automatically manages text chunking and embedding generation, with support for OpenAI and upcoming local models.
• Self-Hostable: Operates on standard PostgreSQL, ensuring no vendor lock-in.
• Visualizer Dashboard: A built-in frontend tool provides real-time debugging capabilities, allowing users to see the reasoning behind memory retrievals.
• Prisma ORM: Ensures type-safe database access for enhanced reliability.

👁️ Visualizer (The "Debugger" for RAG)

Debugging data retrieval can be complex. The MemVault visualizer simplifies this process by allowing developers to validate their retrieval pipelines in real-time.

🚀 API Usage Examples

MemVault enables straightforward API interactions that facilitate memory management for AI agents. For instance, to store a memory and automatically manage chunking and vectorization, the following request can be executed:

curl -X POST http://localhost:4000/api/memory/store  
  -H "Content-Type: application/json"  
  -d '{  
    "sessionId": "agent-007",  
    "text": "The user prefers strictly typed languages like TypeScript.",  
    "importanceHint": "high",  
    "metadata": { "source": "user_chat" }  
  }'  

To retrieve relevant memories based on a specific query, use the following command:

curl -X POST http://localhost:4000/api/memory/retrieve  
  -H "Content-Type: application/json"  
  -d '{  
    "sessionId": "agent-007",  
    "query": "What language should I use for the backend?",  
    "limit": 3  
  }'  

Additionally, to clear history for a session, the following command can be executed:

curl -X POST http://localhost:4000/api/memory/clear  
  -H "Content-Type: application/json"  
  -d '{ "sessionId": "agent-007" }'
