What generate-swagger-json does on Swagger MCP Server

WHY IT NEEDS A POLICY

Why generate-swagger-json needs a policy

This tool fetches a remote resource and writes it to the local filesystem ('saving it under doc/'). It creates/overwrites a file, making it a Write action. The blast radius is medium — it could overwrite existing spec files or introduce malicious content from an untrusted URL, but it is generally reversible.

From the tool's definition "downloads the OpenAPI/Swagger JSON spec from the given URL, saving it under doc/"
