# How to integrate E2b MCP with Atomic Agent ```json { "title": "How to integrate E2b MCP with Atomic Agent", "toolkit": "E2b", "toolkit_slug": "e2b", "framework": "Atomic Agent", "framework_slug": "atomic-agent", "url": "https://composio.dev/toolkits/e2b/framework/atomic-agent", "markdown_url": "https://composio.dev/toolkits/e2b/framework/atomic-agent.md", "updated_at": "2026-08-14T10:05:01.670Z" } ``` ## Introduction Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including E2b. This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a E2b account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate E2b with - [ChatGPT](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) - [Grok Build](https://composio.dev/toolkits/e2b/framework/grok-build) - [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) - [Pi](https://composio.dev/toolkits/e2b/framework/pi-agent) - [DeepSeek Harness](https://composio.dev/toolkits/e2b/framework/deepseek) - [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 ### How Atomic Agent connects to E2b Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect E2b to Atomic Agent ### Connect E2b to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in E2b. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your E2b account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## 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.

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use E2b from Atomic Agent With your account connected, ask Atomic Agent to work with E2b in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone E2b MCP server, the agents and LLMs can only access a fixed set of E2b tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from E2b and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right E2b tools. ### Can I manage the permissions and scopes for E2b while using Tool Router? Yes, absolutely. You can configure which E2b scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your E2b data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
