generate_password · Devutils MCP: Risk & Policy

WHAT IT DOES

What generate_password does on Devutils

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

WHY IT NEEDS A POLICY

Why generate_password needs a policy

This tool generates and returns a new password string, which is a write operation (data creation). It has no side effects on existing systems or data stores, making it Write rather than Execute.

From the tool's definition Tool name 'generate_password' and description 'Generate a secure random password with configurable options' indicate creation of new data (a password artifact).

generate_password Rate-limited

generate_password 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.
