WHAT IT DOES

What set_download_path does on School MCP

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

RISK

Why set_download_path is rated Medium

This tool modifies a user preference/setting by updating the default download directory. It is a write operation because it creates or changes stored configuration data. Severity is low because misconfiguration of a download path has minimal blast radius—it simply changes where files are saved, which is easily reversible by resetting the path.

From the tool's definition Tool name 'set_download_path' and description 'Set the default download path' indicate a configuration modification that creates or updates a setting (where Canvas files will be downloaded).

set_download_path Rate-limited

set_download_path 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.
