Mem0 MCP

Hosted long-term memory that lets Claude save, search and update facts across tools.

Officialby Mem0Hosted, nothing to installChecked October 18, 2026

Mem0's hosted MCP server gives Claude memory tools and lets it choose for itself when to store a fact, retrieve it later or fix something it remembered wrong. The memories live in your Mem0 account rather than on your computer, so the same memory follows you into every MCP client you connect.

Who it is for

  • People who use several AI tools and want one shared memory
  • Developers building personalized agents
  • Teams that want memory stored outside the chat app

Prompts to try

Once it is connected, ask in plain words. Claude decides when to use the server and asks before it changes anything important.

Prompt 1
Remember that our brand voice is friendly and that we never use exclamation marks.
Prompt 2
What do you know about my preferred meeting times?
Prompt 3
Find any memories about the Q4 launch and change the date to November 12.

How we checked it

Checked Mem0's MCP docs, its listing in Claude's connectors directory, the registry entry (io.github.mem0ai/mem0) and the archived mem0ai/mem0-mcp repo that points to this hosted server; the endpoint answers with an OAuth challenge.
