WHAT IT DOES

What to_json does on Windows Operations MCP

AI agents call to_json as a supporting operation in Windows Operations MCP workflows.

WHY IT NEEDS A POLICY

Why to_json needs a policy

The name 'to_json' suggests a data serialization/conversion operation (converting data to JSON format), which is a pure transformation with no side effects. However, the description is empty, so the exact behavior is unknown. Given the context of a Windows system management server, it could be a utility for formatting output. Confidence is low due to lack of description.

From the tool's definition Tool name is 'to_json' and description is empty/uninformative.
