claude-mem
Persistent Context Across Sessions for Every Agent – Captures everything your agent does during sessions, compresses it with AI, and injects relevant context back into future sessions. Works with Claude Code, OpenClaw, Codex, Gemini, Hermes, Copilot, OpenCode + More
claude-mem is an MCP server that provides persistent memory and context management for AI coding agents across sessions. It automatically captures tool usage, generates semantic summaries using AI compression, and injects relevant historical context into future conversations. The server works with Claude Code, OpenClaw, Codex, Gemini, and other AI development environments, enabling agents to maintain continuity of project knowledge even after sessions end or reconnect.

claude-mem — FAQ
What is claude-mem?+
claude-mem is an MCP server that gives AI coding agents persistent memory across sessions by automatically capturing, compressing, and retrieving context from previous interactions. It uses lifecycle hooks to observe tool usage and generate semantic summaries that are injected into future conversations.
How do I install claude-mem?+
Run npx claude-mem install for Claude Code, or npx claude-mem install --ide opencode for OpenCode, or install via the plugin marketplace inside Claude Code with /plugin marketplace add thedotmack/claude-mem. Restart your client after installation to activate the memory system.
Which AI clients work with claude-mem?+
claude-mem works with Claude Code, OpenClaw, Codex, Gemini, Hermes, Copilot, OpenCode, and Antigravity CLI. It can also be integrated with Claude Desktop through the mem-search skill for querying memory from conversations.
Do I need API keys to use claude-mem?+
Yes, you need an AI provider API key (such as Anthropic, OpenAI, or others) for the semantic compression and summarization features. Configuration is managed in ~/.claude-mem/settings.json after first run.
Is claude-mem free to use?+
Yes, claude-mem is open source under the Apache License 2.0. You only pay for the AI provider API usage for compression and summarization, and optional cloud sync to cmem.ai if you choose to enable it.
What are the system requirements?+
claude-mem requires Node.js 20.0.0 or higher, the latest version of your AI client with plugin support, Bun (auto-installed), and optionally uv for vector search (auto-installed). SQLite 3 is bundled for persistent storage.
