create_example_config · Local Code MCP: Risk & Policy

WHAT IT DOES

What create_example_config does on Local Code

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

WHY IT NEEDS A POLICY

Why create_example_config needs a policy

This tool creates (writes) a new configuration file, which is a reversible operation. It does not delete data (not Destructive), execute arbitrary code (not Execute), move money (not Financial), or retrieve data (not Read).

From the tool's definition Tool description explicitly states 'Create an example config.json file'. The verb 'create' indicates file creation, which is a reversible write operation. The scope is limited to creating a configuration example file in specified directories.
