WHAT IT DOES

What create_diagram does on CoWork OS

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

RISK

Why create_diagram is rated Medium

This tool creates diagrams (Write category) but has minimal risk since diagrams are visualization artifacts without side effects on critical data or systems. The blast radius is low—misuse would result in unwanted diagram creation but no data loss, financial impact, or system compromise.

From the tool's definition Tool description states 'Create and display a Mermaid diagram in the UI', indicating it creates new diagram artifacts that are stored or displayed.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_diagram safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_diagram, this is the rule to start with:

create_diagram Rate-limited

create_diagram 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.
