Pensyve — Claude Code MCP server: what it does, how to install
Stores persistent episodic, semantic, and procedural agent memory locally in SQLite. Useful when an assistant needs to recall user preferences across chats.
claude mcp add pensyve -- docker run -i --rm ghcr.io/major7apps/pensyve-mcp:5.0.0What Pensyve does
Pensyve acts as an external memory runtime for AI assistants, keeping facts, conversation history, and task outcomes inside SQLite. Its Rust core processes text using local embedding weights to match entries by meaning. The server gives clients tools such as pensyve_remember, pensyve_recall, pensyve_observe, and pensyve_inspect.
Local setups require no cloud accounts or API keys. Pensyve Cloud shut down on October 1, 2026, so the repository remains in maintenance mode for security patches. Because embedding models download upon first run, offline environments fail unless cache files are prepared in advance.
What it helps with
- persist user preferences and habits across fresh agent sessions
- retrieve previous facts using local semantic vector search
- record task outcomes to evaluate successful procedures
- maintain local agent state in SQLite without external cloud dependencies
Example prompts for the agent
- Remember using pensyve that this project uses Python 3.10 and pytest
- Recall my preferred editor keybindings and theme from memory
- Inspect recorded observations for the current workspace namespace
