For QA & testing teams

QA testing,
without the scripts

Your testers exercise any API in plain language — create test data, reproduce bugs, and validate responses from their AI client. Wrap your API as an MCP server and the whole team is testing in about five minutes.

Live in ~5 minutes

Upload your spec, point it at staging, share the URL. No SDK, no server to run.

Safe by default

Read-only to start, destructive tools off, scoped test credentials, every call logged.

Flows become regressions

Cast spots your recurring test sequences and drafts them into reusable skills.
