Frequently asked questions

Is AI Memory MCP a drop-in replacement for Mem0?

Yes and no. AI Memory MCP focuses on managing existing AI conversations (from ChatGPT, Claude, etc.) with full CRUD operations. Mem0 focuses on extracting structured facts and entities from conversations. If you need to search past conversations across platforms, AI Memory is better. If you need knowledge graph extraction, Mem0 may be more suitable.

Can I use both AI Memory MCP and Mem0 together?

Yes! Both are MCP servers, so you can configure both in your MCP client. Use AI Memory for searching past conversations and Mem0 for extracting structured knowledge. They complement each other well.

Does AI Memory MCP work with Claude Desktop?

Yes. Add the following to your claude_desktop_config.json: {"mcpServers": {"ai-memory": {"command": "aimemory-mcp-server"}}}. Restart Claude Desktop and ask Claude to search your memory.

Why does AI Memory MCP work offline but Mem0 does not?

AI Memory MCP stores all data in a local SQLite database on your machine. It uses stdio transport to communicate directly with your AI client. Mem0 requires a cloud API connection to its servers for all memory operations.

Which is better for privacy — AI Memory MCP or Mem0?

AI Memory MCP is better for privacy. All data stays on your local machine in a SQLite file. No internet connection is required. Mem0 stores your memory on their cloud servers, though they offer encryption options.

How does the search quality compare?

AI Memory uses SQLite FTS5 (full-text search) which is excellent for exact keyword matching, phrase search, and boolean queries. Mem0 uses semantic search (vector embeddings) which is better for concept-based queries. For searching specific conversations you had, FTS5 is typically faster and more precise.
