# Agent memory MCP servers

MCP servers that give an agent long-term memory: store facts, recall them by meaning and build knowledge graphs.

## Before you choose

Remote memory services keep what the agent stores on their side; local servers keep it in a file or database on your machine.

Whatever the agent remembers may include personal data, so check where each server stores it and how you delete it.
