execkit 0.6.1: Python SDK

execkit 0.6: now with a Python SDK

This release brings execkit to Python and ships the MCP server as a pip-installable binary, alongside the Rust crates.

Python SDK: pip install execkit

Native PyO3 bindings to the Rust core (no Rust toolchain needed): stateful, structured, safe shell sessions over local shells, SSH, and Docker.

from execkit import Session, Policy

with Session.local(policy=Policy(deny=["rm"]), timeout=30.0) as s:
    r = s.exec("cd /app && npm ci")
    print(r.stdout, r.exit_code, r.cwd)   # split streams, exit code, cwd

• Session.local() / .ssh(...) / .docker(...) with Pythonic kwargs and a context manager.
• Structured ExecResult (split stdout/stderr, exit code, duration, cwd), secret-redacted and output-bounded.
• Per-call output budgets: exec(cmd, tail=, head=, grep=, max_chars=).
• SSH host-key verification secure by default (TOFU known_hosts); pin= and insecure_accept_any_host_key= are explicit opt-ins.
• Releases the GIL during exec; fully typed (PEP 561 stubs).

MCP server: pip install execkit-mcp

The MCP server now ships as a pip-installable binary wheel (Linux + macOS):

pip install execkit-mcp
claude mcp add execkit -- execkit-mcp
