Include:
- what you found and where (the tool, the URL or the step in the sign-in flow)
- how to reproduce it
- what an attacker could do with it
Never include a real token (fs_... or fso_...) or a recipient's answers. If a token leaked, delete it under OAuth and API Keys in your workspace sidebar first.
This repository holds documentation and example configs only. The policy covers the hosted server at https://api.formstep.io/api/mcp and its OAuth sign-in.
