prisma_generate · Yaver MCP: Risk & Policy

WHAT IT DOES

What prisma_generate does on Yaver

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

WHY IT NEEDS A POLICY

Why prisma_generate needs a policy

Verdict

prisma_generate Rate-limited

prisma_generate 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.
