It runs on Grok 4.5, plans its work before it acts, and can run multiple sub-agents in parallel. It also reads Claude Code's MCP configuration, so any server you already have in a .mcp.json is picked up with no changes. In this guide, I will show you how to connect your E2b account to Grok Build through Composio, so it can run a Python script to analyze CSV data, execute JavaScript code to validate user input, start a sandbox and list installed packages, and more without leaving the terminal. Composio holds the OAuth tokens for you, and Grok Build only calls the tools you approve. ## Also integrate E2b with - [ChatGPT Work](https://composio.dev/toolkits/e2b/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/e2b/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/e2b/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/e2b/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/e2b/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/e2b/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/e2b/framework/codex) - [Cursor](https://composio.dev/toolkits/e2b/framework/cursor) - [VS Code](https://composio.dev/toolkits/e2b/framework/vscode) - [OpenCode](https://composio.dev/toolkits/e2b/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/e2b/framework/openclaw) - [Hermes](https://composio.dev/toolkits/e2b/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/e2b/framework/google-adk) - [LangChain](https://composio.dev/toolkits/e2b/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/e2b/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/e2b/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/e2b/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/e2b/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/e2b/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/e2b/framework/autogen) ## TL;DR ### Why use Composio over a standalone MCP server? - Read and write access. Composio's E2b integration lets Grok Build take real actions like creating drafts, sending updates, and labeling records, not just reading data. - 1,000+ SaaS toolkits out of the box. One endpoint gives you a full catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce. - One MCP server for every app. Wire up a single Composio server instead of maintaining a separate MCP entry for each app. - Smart, context-aware tool loading. Grok Build caps how many tools it holds in a single request. Composio loads only the tools a task needs, so you do not spend that budget on tools you are not using. - Cross-app automation. Chain actions across apps in one run. Pull a thread, summarize it in Notion, and post the highlights to Slack from a single prompt. ## Connect E2b to Grok Build ### Prerequisites - Grok Build installed and signed in. Install with curl -fsSL https://x.ai/cli/install.sh | bash on macOS or Linux, or irm https://x.ai/cli/install.ps1 | iex on Windows PowerShell. On first launch Grok opens a browser to authenticate; for headless or CI use, set an XAI_API_KEY environment variable instead (create the key at [console.x.ai](https://console.x.ai/)). - Access to the E2b account you want to connect. - The [Composio MCP endpoint](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=grok-build&utm_content=composio_connect). Composio's server is remote and hosted, so there is nothing to run locally and no tunnel to set up. ### Step-by-step: Connect E2b to Grok Build ### 1. Install and verify Grok Build Install the CLI, then restart your shell so the grok binary lands on your PATH: ```bash curl -fsSL https://x.ai/cli/install.sh | bash which grok ``` ## What is the E2b MCP server, and what's possible with it? The E2b MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your E2b account. It provides structured and secure access so your agent can perform E2b operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `E2B_CONNECT_SANDBOX` | Connect to Sandbox | Tool to connect to an existing E2B sandbox and retrieve its details.

A standalone E2b MCP server gives Grok Build a fixed set of E2b tools tied to that one server. The Composio Tool Router lets Grok Build load tools from E2b and many other apps on demand, based on the task, all through a single endpoint. ### Does Grok Build support MCP? Yes. Grok Build ships with native MCP support. Add a server with the grok mcp add command, from the in-session /mcps modal, or by editing ~/.grok/config.toml. It also reads Claude Code-style .mcp.json files, so Grok Build discovers the tools automatically. ### Can I reuse the same MCP config I already use with Claude Code? Yes. Grok Build has zero-migration compatibility with Claude Code's configuration, so the same Composio server entry works in both without edits. ### How safe is my E2b data with Composio? Tokens, keys, and configuration are encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant, so your E2b data and credentials are handled to that standard. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
