Model Context Protocol Servers
The Memory MCP Server gives your AI a persistent, knowledge-graph-based memory — facts, preferences, and relationships you tell it are stored and recalled across conversations.
For example, once you say "I'm building a directory site called mcpradars," the AI can remember that context in a new conversation later. This is an official MCP reference implementation.
What it does for you
Gives your AI a persistent memory — stores key facts as a knowledge graph so it remembers across conversations.
Capabilities
- Store entities and relations
- Retrieve remembered facts
- Update / delete memories
Once installed, try asking your AI
Say this directly in Claude / Cursor or any client with this server connected
- ›“Remember I'm building MCP Radar with a Next.js stack”
- ›“Do you remember the preferences I told you earlier?”
Why use it
Good for: anyone who wants the AI to remember long-term context instead of re-explaining background each time.

Frequently Asked Questions
Where is the memory stored?
Locally, where the server runs — not sent to a third-party cloud.
How do I make it forget something?
Just ask the AI to delete a specific memory and it updates the knowledge graph.
