SimpleMem: Efficient Lifelong Memory for LLM Agents — Text & Multimodal
SimpleMem is an MCP server that provides efficient long-term memory capabilities for LLM-based AI agents through semantic compression and intelligent retrieval. It processes dialogues and interactions into compact, searchable memory units using a three-stage pipeline: semantic structured compression, online synthesis, and intent-aware retrieval planning. The system reduces token consumption by approximately 30x while improving recall accuracy by 26.4% over existing memory solutions. SimpleMem is available as a cloud-hosted service via MCP protocol or can be self-hosted using Docker, with support for Claude Desktop, Cursor, and other MCP-compatible clients.
Key Features
Use Cases
- 01Enabling AI assistants in Claude Desktop or Cursor to recall past conversations and user preferences across sessions

SimpleMem — FAQ
What is SimpleMem MCP server?+
SimpleMem is an MCP server that provides long-term memory capabilities for AI agents through semantic compression and intelligent retrieval. It stores interactions as compact memory units and retrieves relevant context based on meaning rather than keywords, reducing token usage by approximately 30x while improving accuracy.
How do I install SimpleMem in Claude Desktop?+
Add the SimpleMem server configuration to your Claude Desktop MCP settings JSON file with the cloud service URL (https://mcp.simplemem.cloud/mcp) and your authorization token in the headers. Alternatively, you can self-host using Docker and point to your local instance at http://localhost:8000/mcp/sse.
Which AI clients work with SimpleMem?+
SimpleMem works with any MCP-compatible client including Claude Desktop, Cursor, LM Studio, and Cherry Studio. The cloud service supports the MCP 2025-03-26 protocol with JSON-RPC 2.0 over streamable HTTP.
Do I need an API key to use SimpleMem?+
Yes, you need an OpenAI-compatible API key configured for memory construction and retrieval operations. SimpleMem supports OpenAI, Qwen, Azure OpenAI, Atlas Cloud, and other compatible providers. For the cloud service, you also need a SimpleMem authentication token.
Is SimpleMem free to use?+
SimpleMem is open-source under the MIT License, so the software itself is free. However, you'll incur costs from your chosen LLM and embedding model API provider. The cloud-hosted MCP service at mcp.simplemem.cloud requires registration; pricing details are available on their website.
Can I self-host the SimpleMem MCP server?+
Yes, SimpleMem can be self-hosted using Docker with the included docker-compose.yml configuration. Data is persisted in a host volume, and you can configure your own LLM provider, embedding models, and authentication settings via environment variables.
