protect_data · Thales Cdsp Crdp MCP: Risk & Policy

WHAT IT DOES

What protect_data does on Thales Cdsp Crdp

AI agents use protect_data to create or update resources in Thales Cdsp Crdp — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Thales Cdsp Crdp environment.

WHY IT NEEDS A POLICY

Why protect_data needs a policy

This tool encrypts or tokenizes sensitive data, which is a write/transform operation. It does not delete data irreversibly, execute arbitrary code, or move money. Since the sibling tool 'reveal_data' can reverse the operation, it is not destructive. However, misuse could expose sensitive data or corrupt protection schemes, warranting high severity.

From the tool's definition 'Protect sensitive data using CipherTrust CRDP' — the tool transforms/encrypts data and writes the protected form, implying a reversible transformation (data can be revealed via reveal_data/reveal_bulk sibling tools).

Verdict

protect_data Rate-limited

protect_data 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.
