vercel_create_deployment · Integrations MCP: Risk & Policy

WHAT IT DOES

What vercel_create_deployment does on Integrations MCP

AI agents invoke vercel_create_deployment to trigger actions in Integrations MCP. 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 vercel_create_deployment needs a policy

Creating a deployment on Vercel triggers an external operation that builds and publishes code to infrastructure. This falls under Execute as it runs an external pipeline/operation. The blast radius is high because a misused deployment could push malicious or broken code to production environments. Confidence is reduced due to the empty description.
