e2b-server MCP Server

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

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

Modify your e2b sandbox template ID in e2b.toml and src/index.ts file.

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": [
        "<absolute-path-to-e2b-server>/js/build/index.js"
      ],
      "env": {
        "E2B_API_KEY": "<your-e2b-api-key>"
      }
    }
  }
}

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.
