Verdict

Pick InstantDB MCP if you prefer the more popular, battle-tested option, and you want a hosted/remote server with nothing to install.

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

Add InstantDB MCP

Install / run

npx -y @instantdb/mcp --token <token>

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

{
  "mcpServers": {
    "instantdb-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.instantdb.com/mcp"
      ]
    }
  }
}

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

Add MongoDB Lens

Install / run

npx -y mongodb-lens@latest

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

{
  "mcpServers": {
    "mongodb-lens": {
      "command": "/path/to/npx",
      "args": [
        "-y",
        "mongodb-lens@latest",
        "mongodb://your-connection-string"
      ]
    }
  }
}
