<!-- CURSOR_SUMMARY --> > [!NOTE] > Promotes MCP to stable across JS/Python SDKs: add `mcp` config to sandbox creation, auto-select MCP template, start gateway with token, rename beta APIs to stable (`getMcpUrl`/`getMcpToken`, `addMcpServer`). > > - **JS SDK**: > - **Sandbox creation**: `Sandbox.create` now accepts `opts.mcp`; auto-selects `defaultMcpTemplate`, starts `mcp-gateway` with generated token, and returns initialized sandbox. > - **API opts**: Move `mcp` from `SandboxBetaCreateOpts` to `SandboxOpts`; pass `mcp` through `SandboxApi.createSandbox`. > - **Stable MCP APIs**: Rename `betaGetMcpUrl` -> `getMcpUrl`, `betaGetMcpToken` -> `getMcpToken`. > - **Template builder**: Rename `betaAddMcpServer` -> `addMcpServer`. > - **Tests**: Update stacktrace tests to new method names. > - **Python SDK**: > - **Sandbox creation**: `AsyncSandbox.create`/`Sandbox.create` accept `mcp`; auto-select MCP template when unset, start `mcp-gateway`, store token. > - **Stable MCP APIs**: Add `get_mcp_url`; rename `beta_get_mcp_token` -> `get_mcp_token`. > - **Types**: Minor signature tweaks (e.g., `secure` default handling). > - **Tests**: Update stacktrace tests to new method names. > - **Release**: > - Changeset: minor version bumps for `@e2b/python-sdk` and `e2b`. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 9c673f80eee37e530d05c6becf5a4a3c492ac9f3.

What is E2B?
E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.
Run your first Sandbox
1. Install SDK
npm i @e2b/code-interpreter
2. Get your E2B API key
E2B_API_KEY=e2b_***
3. Execute code with code interpreter inside Sandbox
import { Sandbox } from '@e2b/code-interpreter'
const sbx = await Sandbox.create()
await sbx.runCode('x = 1')
const execution = await sbx.runCode('x+=1; x')
console.log(execution.text) // outputs 2
4. Check docs
Visit E2B documentation.
5. E2B cookbook
Visit our Cookbook to get inspired by examples with different LLMs and AI frameworks.
