Preview which compliance controls a proposed evidence record would earn — without writing
AI agents call dry_run_attest to retrieve information from Governance Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool explicitly performs a dry-run/preview operation and states it operates 'without writing', meaning it only simulates and reads/evaluates what controls would be satisfied. No data is created, modified, or deleted. This is a pure read/query operation with minimal blast radius.
