Why depguard_should_use needs a policy

The description is incomplete and provides no meaningful information about what the tool does. Based on the name 'depguard_should_use' and its context among security audit/analysis tools, it likely performs a read/query operation to advise whether a dependency should be used, but this cannot be confirmed. Lowering confidence significantly due to the uninformative description.

POLICY

How to control depguard_should_use

PolicyLayer is an MCP gateway — it sits between your AI agents and Depguard, and nothing reaches the server without passing your rules. This is the rule we recommend for depguard_should_use:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "depguard_should_use": {}
  }
}

depguard_should_use is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Depguard — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
