set_project_pin · Assetcache MCP: Risk & Policy

WHAT IT DOES

What set_project_pin does on Assetcache

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

WHY IT NEEDS A POLICY

Why set_project_pin needs a policy

This tool modifies project state by pinning or blocking asset packs, which is a configuration change. It is not destructive (the change is reversible), does not execute arbitrary code or delete data, and affects only metadata/settings. The severity is medium because misuse could prevent access to legitimate assets or lock unwanted packs, impacting workflow but not causing permanent data loss.

From the tool's definition Tool name 'set_project_pin' and description '프로젝트에 특정 팩을 고정/차단한다' (Sets/pins/blocks specific packs in a project) indicates modifying project configuration settings. The action is reversible (pins can be unpinned).

Verdict

set_project_pin Rate-limited

set_project_pin 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.
