E2B

Arcade toolkit · docs.arcade.dev

The E2B toolkit integrates E2B sandboxed code execution into Arcade, enabling LLMs to run arbitrary code and generate visualizations in a secure, isolated environment.

Capabilities

  • Sandboxed code execution: Run code snippets and capture stdout/stderr output without risk to the host environment.
  • Matplotlib chart generation: Execute Python code that produces static matplotlib figures; results are returned as base64-encoded images ready for display or further processing.

Secrets

This toolkit requires the following secret:

  • E2B_API_KEY: An API key issued by E2B that authenticates requests to their sandbox API. Obtain it by signing in to the E2B dashboard, navigating to API Keys, and creating a new key. A free tier is available; higher usage limits require a paid plan. The key is a long alphanumeric string prefixed with e2b_.

Configure secrets in Arcade at https://docs.arcade.dev/en/guides/create-tools/tool-basics/create-tool-secrets or via the Arcade secrets dashboard.
