MCP Memory: Empowering AI Clients with Persistent Memory

In the rapidly evolving landscape of AI and Large Language Models (LLMs), context is king. Applications need to understand user preferences, past interactions, and evolving needs to deliver truly personalized and effective experiences. This is where MCP Memory steps in, providing a robust and scalable solution for giving MCP Clients (like Cursor, Claude, and Windsurf) the ability to remember information about users across conversations.

MCP Memory is a specialized MCP Server, leveraging cutting-edge vector search technology to move beyond simple keyword matching. It understands the semantic meaning of information, allowing it to retrieve relevant memories even when the exact words aren’t present in a query. Built entirely on Cloudflare’s powerful infrastructure, including Workers, D1, Vectorize (RAG), Durable Objects, Workers AI, and Agents, MCP Memory offers a cost-effective and highly performant solution for AI memory management.

Key Features and Benefits:

• Persistent User Memory: Enables AI clients to remember user preferences, behaviors, and past interactions across multiple conversations. This leads to more personalized and context-aware AI experiences.
• Semantic Vector Search: Uses vector embeddings to understand the meaning of text, allowing for more accurate and relevant memory retrieval compared to keyword-based approaches. This ensures that the AI client receives the most pertinent information, even if the user phrases their query differently.
• MCP Protocol Compliance: Adheres to the Model Context Protocol (MCP), ensuring seamless integration with other MCP-compatible AI agents and tools.
• Cloudflare-Native Architecture: Leverages the power and scalability of Cloudflare’s infrastructure, including Workers, D1, Vectorize, Durable Objects, and Workers AI, providing a reliable and cost-effective solution.
• Open-Source and Customizable: Offers full control over your data and the ability to customize the system to meet your specific needs.
• Easy Deployment: Can be deployed with a single click to Cloudflare, making it easy to get started quickly. Alternative deployment options are also available for more advanced users.
• Cost-Effective: Free for most users due to Cloudflare’s generous free tier for Workers, Vectorize, Worker AI, and D1 database.
• Secure: Implements several security measures to protect user data, including isolated namespaces, rate limiting, and TLS encryption.

Use Cases:

MCP Memory unlocks a wide range of possibilities for AI-powered applications, including:

• Personalized AI Assistants: Create AI assistants that remember user preferences, past conversations, and individual needs to provide more tailored and helpful responses.
• Context-Aware Chatbots: Build chatbots that understand the context of the conversation and can provide more relevant and accurate information.
• Improved Customer Service: Enhance customer service interactions by providing agents with access to a customer’s past interactions and preferences.
• Smarter E-commerce Recommendations: Provide more personalized product recommendations based on a user’s browsing history and past purchases.
• Enhanced Educational Tools: Create educational tools that adapt to a student’s learning style and track their progress over time.
• Optimized Code Completion and Generation: IDE can remember context and provide better auto-completion and code-generation suggestions.
• Better meeting summary and key point extraction: AI Agent can remember context of ongoing meeting to give better summary.

How MCP Memory Works:

The architecture of MCP Memory is designed for efficiency, scalability, and security:

1. Storing Memories: When new text is stored, it is processed by Cloudflare Workers AI using the open-source @cf/baai/bge-m3 model to generate embeddings. These embeddings capture the semantic meaning of the text.
2. Data Storage: The text and its vector embedding are stored in two separate locations: Cloudflare Vectorize stores the vector embeddings for similarity search, while Cloudflare D1 stores the original text and metadata for persistent storage.
3. Durable Object Management: A Durable Object (MyMCP) manages the state and ensures consistency between the Vectorize index and the D1 database.
4. Retrieving Memories: When a query is received, it is converted to a vector using Workers AI with the same @cf/baai/bge-m3 model.
5. Similarity Search: Vectorize performs a similarity search to find relevant memories based on the vector embeddings. The results are ranked by similarity score.
6. Data Retrieval: The D1 database provides the original text for the matched vectors.

This architecture allows for fast vector similarity search, persistent storage, stateful operations, standardized AI interactions, and MCP protocol compliance.

Getting Started with MCP Memory:

Deploying your own instance of MCP Memory is easy with Cloudflare. You can use the one-click deploy button, use the template, or use Cloudflare CLI. Detailed instructions are provided in the MCP Memory documentation.
