E2B is an open-source runtime that lets your agents execute AI-generated code securely in isolated cloud sandboxes.

​
Setup

  1. In Agent Studio, go to Tools → E2B → Connect
  2. Paste your API key from the E2B dashboard

​
Available actions

ActionDescription
E2B__RUN_CODERuns a Python code snippet inside a secure E2B cloud sandbox and returns the output.

​
Adding to an agent

  1. Open your agent in Agent Studio → Agent Builder
  2. Go to Tools and enable E2B
  3. Select only the actions your agent needs
  4. Set auth mode: Shared (agent acts on one account) or Per-user (each end-user connects their own account)

​
Example use cases

Automated data analysis pipelines An agent receives a CSV file and writes Python code to clean, transform, and summarize the data, then executes it in the E2B sandbox to return results without any risk to the host environment. AI-generated report generation An agent dynamically writes and runs Python scripts to generate charts, perform statistical calculations, and produce formatted reports based on user-supplied datasets. Safe code execution for developer assistants A coding assistant agent writes Python solutions to user problems and immediately validates them by running the code in an isolated sandbox, confirming correctness before returning the answer.
