Notes
Marked experimental. The Docker image includes k6; Homebrew and native installs use claude mcp add --scope=user --transport=stdio k6 mcp-k6. validate_script runs a script with 1 VU and 1 iteration, run_script runs a local test with optional VU, duration and iteration overrides, and the generate_script prompt drafts tests from plain-English requirements. The README gives a JSON config for Codex CLI. A shared deployment has no built-in authentication. Load tests send real traffic, so aim them at systems you run.
