Overview

The E2B MCP Server integrates E2B sandbox technology into your Claude Desktop application. It enables AI models to perform code execution in a dedicated environment, allowing for tasks that require isolated computing resources. The repository provides implementations in both JavaScript and Python. Users can configure the server manually or through the Smithery CLI to add these sandboxed capabilities to their AI workflows.

Our verdict

This server carries a high risk level with a security score of 7/100. It is officially archived and no longer maintained, meaning no future bug fixes or security patches will be issued. Furthermore, the absence of an authentication method allows anyone with access to the configuration to use the server, which presents a significant security concern for production environments. It is not recommended for new implementations.

Setup

Claude Desktop

{
  "mcpServers": {
    "mcp-server": {
      "args": [
        "-y",
        "e2b-mcp-root"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

No read-only mode — running this grants full read/write access.
No built-in authentication — anyone with access to this config can invoke every tool it exposes.
