What are the key features of Mem0 MCP Server?

Key features include creating memory streams, appending content, semantic search via Mem0, resource-based access, and reading/deleting streams.

Does Mem0 MCP Server use the Mem0 API?

Yes, it leverages the Mem0 API for persistent memory storage and semantic search capabilities.

What credentials does it need?

It reads `MEM0_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
