Verdict

Pick OMOP MCP Server if you want a local (stdio) server that keeps data on your machine.

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

Add OMOP MCP Server

Install / run

git clone https://github.com/OHNLP/omop_mcp.git

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

{
  "mcpServers": {
    "omop-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "<path-to-local-repo>",
        "run",
        "omop_mcp"
      ]
    }
  }
}

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.
