## AI overview

Heroku describes code execution sandboxes for AI agents, using ephemeral one-off dynos to isolate untrusted code. The article explains built-in and MCP-based integrations and how programmatic tool calling can reduce context usage.

## Source excerpt

Large language models are good at writing code. Data from Anthropic shows that allowing Claude to execute scripts, rather than relying on sequential tool calls, reduces token consumption by an average of 37%, with some use cases seeing reductions as high as 98%. Untrusted code needs a secure and isolated place to execute. We solved [...] The post Code Execution Sandbox for Agents on Heroku appeared first on Heroku.
