How do I find my Contrast Security API credentials?

Log into your Contrast Security web interface. Navigate directly to your profile dropdown via **User Settings** -> **Profile**. Here you will find your distinct Authorization Key (encoded string), API Key, and the required Organization UUID at the very top.

What exactly is termed a 'Trace' in the Contrast ecosystem?

A Trace is the Contrast terminology applied to a single explicit instance of a security vulnerability uncovered deep within an executing application. Every trace holds a massive amount of payload data concerning the attack vectors.

Can I use this MCP integration to completely delete trace incidents?

No. The integration architecture focuses heavily on purely read-only auditing workflows. Features like permanently overwriting and deleting incident historical data are prohibited to ensure strong forensic compliance logs.
