create_pynet_module · PyNet Bridge MCP: Risk & Policy

WHAT IT DOES

What create_pynet_module does on PyNet Bridge

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

WHY IT NEEDS A POLICY

Why create_pynet_module needs a policy

This tool creates a new UI module/tab in the Ribbon, which is a reversible modification to the application's state. The presence of a complementary 'delete_pynet_module' tool on the same server confirms this is Write (reversible) rather than Destructive.

From the tool's definition Tool name: 'create_pynet_module'; description states it 'Creates a new custom Tab (ButtonsModule) in the Ribbon' - the verb 'Creates' and action of adding a new UI component indicates data/state modification.
