Interactive Console
Exposes a long-lived interactive REPL for R or Python with stateful execution, plot visualization, and OS-level sandboxing.
Provides a long-lived interactive REPL process through a single write_stdin tool, supporting both R and Python backends. Maintains session state across calls, enabling iterative code execution and debugging. Features include automatic prompt cleanup, a built-in pager for large outputs, in-band documentation access, plot rendering as image content, and OS-level sandboxing with network disabled by default and memory guardrails. Supports macOS and Linux.
