WHY IT NEEDS A POLICY

Why createTag needs a policy

This tool creates a tag, which is a reversible write operation that stores or modifies data. It does not execute code, delete data irreversibly, move money, or read sensitive data. The low severity reflects minimal blast radius—tags are typically lightweight metadata constructs used for organization and categorization in a note-taking application.

From the tool's definition Tool name 'createTag' with description 'Create a tag' indicates creation of a new metadata entity without destructive side effects or code execution.

Verdict

createTag Rate-limited

createTag 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.
