n8n-nodes-e2b

Unofficial n8n community node for E2B Code Interpreter. Run Python and JavaScript code in secure cloud sandboxes directly from your n8n workflows.

This node wraps the @e2b/code-interpreter SDK and exposes sandbox lifecycle operations as individual n8n actions, allowing you to freely compose them within your workflows.

Installation

1. Open your n8n instance
2. Go to Settings > Community Nodes
3. Click Install a community node
4. Enter n8n-nodes-e2b
5. Click Install

Prerequisites

You need an E2B API key. Sign up at e2b.dev and get your API key from the dashboard.

Credential Setup

1. In n8n, go to Credentials > Add Credential
2. Search for E2B API
3. Enter your API key
4. Click Save

Operations

The node provides a single Sandbox resource with 7 operations:

Create Sandbox

Create a new sandbox and return its ID for subsequent operations.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Template | string | (empty) | Custom sandbox template ID | | Timeout (Seconds) | number | 300 | Auto-kill timeout (max 86400; requires Pro plan for >3600) | | Environment Variables | key-value | (empty) | Environment variables passed to the sandbox |

Output:

{ "sandboxId": "sandbox-xxxx" }

Execute Code

Execute Python or JavaScript code inside a sandbox.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID | | Code | string | (required) | Code to execute (multiline) | | Language | options | python | python or javascript |

Output:

{
  "sandboxId": "sandbox-xxxx",
  "stdout": "...",
  "stderr": "...",
  "results": [],
  "error": ""
}

• results contains structured data from code execution (charts, images, etc.)
• error contains the error message if execution failed

Run Command

Run a shell command inside a sandbox.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID | | Command | string | (required) | Shell command to run | | Working Directory | string | / | Working directory for the command |

Output:

{
  "sandboxId": "sandbox-xxxx",
  "stdout": "...",
  "stderr": "...",
  "exitCode": 0
}

Upload File

Upload a file to a sandbox. Supports both text content and binary data from previous n8n nodes.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID | | Remote Path | string | (required) | Destination path inside the sandbox | | Content | string | (empty) | File content as text (ignored when binary input is used) | | Binary Property | string | data | Name of the input binary property. Binary data takes priority over Content. |

Output:

{
  "sandboxId": "sandbox-xxxx",
  "remotePath": "/home/user/data.csv",
  "success": true
}

Download File

Download a file from a sandbox as text or binary data.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID | | Remote Path | string | (required) | File path inside the sandbox | | Binary Output | boolean | false | Output as n8n binary data instead of text |

Output (text):

{
  "sandboxId": "sandbox-xxxx",
  "remotePath": "/home/user/result.txt",
  "content": "..."
}

Output (binary): Returns n8n binary data that can be used by downstream nodes (e.g., Write Binary File).

List Files

List files and directories in a sandbox.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID | | Path | string | / | Directory path to list |

Output:

{
  "sandboxId": "sandbox-xxxx",
  "path": "/home/user",
  "files": [
    { "name": "data.csv", "type": "file" },
    { "name": "output", "type": "dir" }
  ]
}

Kill Sandbox

Terminate a sandbox and release its resources.

| Parameter | Type | Default | Description | |-----------|------|---------|-------------| | Sandbox ID | string | (required) | Target sandbox ID |

Output:

{
  "sandboxId": "sandbox-xxxx",
  "killed": true
}
