SETUP GUIDE
Connect E2b MCP Tool with your Agent
1
Install Composio
typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcpInstall the Composio SDK for Python or TypeScript

3
Connect to AI Agent
typescript

},
});
const tools = await client.tools();
const { text } = await generateText({
model: openai('gpt-4o'),
tools,
messages: [{
role: 'user',
content: 'Run a Python script to check if a string is a palindrome.'
}],
maxSteps: 5,
});
console.log(`Agent: ${text}`);Use the MCP server with your AI agent (Anthropic Claude or Mastra)
SETUP GUIDE
Connect E2b API Tool with your Agent
1
Install Composio
typescript
npm install @composio/openaiInstall the Composio SDK
2
Initialize Composio and Create Tool Router Session
typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';
const composio = new Composio({
provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');Import and initialize Composio client, then create a Tool Router session
3
Execute E2b Tools via Tool Router with Your Agent
typescript
const tools = session.tools;
const response = await openai.responses.create({
model: 'gpt-4.1',
tools: tools,
input: [{
role: 'user',
content: 'Run a Python script to sort a list of numbers.'
}],
});
const result = await composio.provider.handleToolCalls(
'your-user-id',
response.output
);
console.log(result);Get tools from Tool Router session and execute E2b actions with your Agent
Why Use Composio?
Managed Auth
- Built-in OAuth handling with automatic token refresh and rotation
- Central place to manage, scope, and revoke E2b access
- Per user and per environment credentials instead of hard-coded keys

FAQ
Frequently asked questions
Yes, E2b requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you.
Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.
Yes. Composio is SOC 2 Type II compliant and is built to keep your E2b connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.
Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.
Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.
Create the key in your E2b account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the E2b actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside E2b at any time.
When you connect a E2b account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in E2b as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.
Whatever the credentials you connect allow inside E2b. If E2b lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside E2b at any time.
Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each E2b connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.
The connection stops working the moment E2b rejects the old key. Create a new key in E2b and reconnect the account from the Composio dashboard or by asking your agent to reconnect E2b. Nothing else changes.
Composio's free plan includes 100,000 tool calls per month with no credit card, which covers most personal E2b use. Paid plans add higher limits and team features. Your E2b plan and its API limits still apply as usual.
Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple E2b accounts).
With Composio, you connect E2b once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
