confirm_workflow · MCP for Vivado MCP: Risk & Policy

WHAT IT DOES

What confirm_workflow does on MCP for Vivado

AI agents invoke confirm_workflow to trigger actions in MCP for Vivado. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why confirm_workflow needs a policy

Confirming a workflow in a hardware design automation context triggers the execution of the confirmed workflow steps (synthesis, implementation, etc.), making it an Execute-category action. The blast radius is high because hardware synthesis and implementation workflows can consume significant compute resources and produce hardware artifacts.
