A Model Context Protocol server for running code in a secure sandbox by E2B.

Development

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "e2b-server": {
      "command": "node",
      "args": ["/your_path/mcp-server/packages/js/build/index.js"],
      "env": {
        "E2B_API_KEY": "${e2bApiKey}",
        "E2B_ALLOWED_UPLOAD_PATHS": "${your_local_paths}"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
