# Omega Memory (MCP server)

> Omega Memory is an MCP server that adds developer tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Persistent memory for AI coding agents. #1 on LongMemEval. It has 219 GitHub stars, is released under the Apache-2.0 license and runs locally with uvx omega-memory.

Cross-model memory for AI agents. Local-first. Works with Claude, GPT, Gemini, Cursor, Claw Code, and any MCP client. Your agent's brain shouldn't live on someone else's server, or be locked to one provider.
