power · MCP Calculator Server MCP: Risk & Policy

WHAT IT DOES

What power does on MCP Calculator Server

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

power Rate-limited

power 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.
