Verdict

Pick Sequential Thinking if you want a local (stdio) server that keeps data on your machine, and you want zero-setup with no API key.

Pick OpenMemory MCP if you want a hosted/remote server with nothing to install, and you need the broadest set of tools.

Add Sequential Thinking

Install / run

npx -y @modelcontextprotocol/server-sequential-thinking

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "sequential-thinking": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    }
  }
}

Add OpenMemory MCP

Install / run

curl -sL https://raw.githubusercontent.com/mem0ai/mem0/main/openmemory/run.sh | OPENAI_API_KEY=your_api_key bash

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "openmemory-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:8765/mcp/<client-name>/sse/<user-id>"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
