Python SDK

execkit-py wraps the same Rust core with a Python API, published to PyPI as execkit.

pip install execkit

from execkit import Session, Policy

s = Session.local(policy=Policy(allow=[], deny=["rm"]))
r = s.exec("echo hi; echo err 1>&2; cd /tmp")
print(r.stdout, r.exit_code, r.cwd)   # "hi" 0 "/tmp"
s.close()

The result object mirrors the Rust ExecResult: split stdout / stderr, exit_code, duration_ms, cwd, and truncated, already ANSI-stripped and secret-redacted. State persists across exec calls on the same session.

SSH and Docker sessions work through Session.ssh(...) / Session.docker(...) with the same options as Transports. Output budgets are keyword arguments (tail, head, grep, max_chars) on the session constructors and on exec. Checkpoints are not exposed in the Python SDK yet; use the Rust library or the MCP server for those.

Wheels ship for Linux and macOS, so no Rust toolchain is needed to install.
