Mem0 Long-Term Memory

What it does

This MCP server provides AI agents with a persistent, long-term memory layer based on mem0.ai. It allows agents to store, retrieve, and manage user preferences, historical context, and specific facts across different sessions, ensuring that the AI remembers previous interactions without relying solely on the limited context window.

Tools

• memory_save: Stores specific information or facts into the long-term memory database.
• memory_get_all: Retrieves all stored memories in a contextual format for the agent to review.
• memory_search: Performs semantic search to find the most relevant memories based on a query.
• memory_delete: Removes specific memories from the database using a search query.
