Verdict

Pick Atlan MCP Server if you want a local (stdio) server that keeps data on your machine, and you need the broadest set of tools.

Pick OpenMemory MCP if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add Atlan MCP Server

Install / run

uvx atlan-mcp-server

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

{
  "mcpServers": {
    "atlan-mcp-server": {
      "command": "uvx",
      "args": [
        "atlan-mcp-server"
      ],
      "env": {
        "ATLAN_API_KEY": "<YOUR_API_KEY>",
        "ATLAN_BASE_URL": "https://<YOUR_INSTANCE>.atlan.com",
        "ATLAN_AGENT_ID": "<YOUR_AGENT_ID>"
      }
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

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.
