What signup_user does on Red Bee MCP Server

WHY IT NEEDS A POLICY

Why signup_user needs a policy

This tool creates a new user account on the platform. It is a reversible write operation (accounts can be deleted), not destructive. While it could be misused to create fake accounts, it does not move money, execute code, or irreversibly destroy data. Severity is medium due to potential for account abuse or spam registration.

Verdict

signup_user Rate-limited

signup_user stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
