Engram-MCP: Persistent Memory Server for AI Agents

Engram-MCP is a Rust-based MCP server designed to provide persistent memory capabilities for AI agents. Built for developers working with AI agents and MCP (Multi-Agent Communication Protocol), it addresses the critical need for agents to retain and access contextual information across sessions and interactions. This tool facilitates the development of more sophisticated and stateful AI agents by offering robust memory management and retrieval mechanisms.

What Engram-MCP Does

Engram-MCP acts as a central repository for AI agent memory. It allows agents to store, retrieve, and query their past experiences, learned information, and contextual data in a structured and efficient manner. This persistent memory is crucial for agents that need to maintain long-term coherence, learn from interactions, and adapt their behavior over time. By leveraging local ONNX embeddings and SQLite, it provides powerful semantic search capabilities, enabling agents to find relevant memories based on meaning rather than just keywords.

Key Features

• Rust-based Performance: Built with Rust for high performance and memory safety, ensuring reliability for demanding AI applications.
• Branch-Aware Session Handoffs: Supports seamless transfer of agent state and memory between different branches or versions of an agent, crucial for iterative development and experimentation.
• Local ONNX Embeddings: Integrates local ONNX runtime for generating embeddings, allowing for efficient and private semantic representation of memory content.
• SQLite-backed Semantic Search: Utilizes SQLite for persistent storage and efficient semantic search, enabling agents to query their memory based on conceptual similarity.
• MCP Protocol Compliance: Designed to integrate smoothly within existing MCP-based agent architectures.

Who Engram-MCP is For

Engram-MCP is specifically targeted at AI developers and researchers building multi-agent systems or individual AI agents that require persistent memory. This includes:

• Developers working on complex AI agents that need to learn and adapt over extended periods.
• Teams building multi-agent simulations or environments where agents must recall past interactions.
• Researchers exploring long-term memory mechanisms for AI.
• Developers already utilizing or looking to implement the MCP protocol for agent communication.
