Code Execution (Claude)
The Code Execution (Claude) tool (anthropic_code_execution) is a native feature from Anthropic that allows Claude to write and execute code in a secure sandbox environment. Similar to OpenAI Code Interpreter, but optimized for Claude.
Code execution is always off in standard chats, even if the environment or your personal settings say otherwise. Switch the tool on in the tool settings of an assistant, lesson or workflow that needs calculations or file editing. Code execution can take longer and add costs.
How It Works
Claude can write and directly execute code to perform calculations, analyze data, and create visualizations. The code runs in an isolated environment for maximum security.

Security
Code execution happens in a sandbox:
- ✅ Isolated environment
- ✅ No network access from sandbox
- ✅ Limited system access
- ✅ Time limit on execution
Comparison with OpenAI Code Interpreter
Both tools offer similar functionality:
| Claude Code Execution | OpenAI Code Interpreter |
|---|---|
| Optimized for Claude | Optimized for GPT |
| Anthropic sandbox | OpenAI sandbox |
| Claude's reasoning | GPT's reasoning |
The choice depends on which model you use - use the native tool of the chosen provider for best results.
Limitations
- Only available with Anthropic Claude models
- Limited library support
- Maximum execution time
- Sessions are temporary
