# Hippo Memory (MCP server)

> Hippo Memory is an MCP server that adds database tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Stop re-teaching your agent. Make your agent's memory work like a brain. It has 773 GitHub stars, is released under the MIT license and runs locally with npx -y hippo-memory.

Make your agent's memory work like a brain. Hippo is long-term memory for coding agents. It's a critical layer for your AI harness that connects across your different tools (Cursor, Claude Code, Codex). It keeps your proprietary data completely local, and it actually learns over time. By strengthening memories each time they are recalled, Hippo preserves what works, lets mistakes decay, and continuously compounds your agents' intelligence.
