WHAT IT DOES

What create_design does on Ncp

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

RISK

Why create_design is rated Medium

This tool creates new design assets in Canva, which is a reversible Write operation. It generates new data/content but does not execute arbitrary code, delete data, or involve financial transactions. Severity is medium because misuse could flood a Canva account with unwanted designs or consume design quotas, but the impact is limited to design creation and remains reversible.

From the tool's definition Tool name is 'create_design' and description states 'Create Canva design', which creates new content in Canva (a design platform).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_design safely

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

create_design Rate-limited

create_design 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.

      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every create_design call is checked against it from then on.
