THE RISK

Low Risk

Why depguard_search needs a policy

This tool queries a package registry (npm) to retrieve package metadata filtered by keywords. It is fundamentally a read-only search operation with no side effects, no data modification, and no code execution. The output is informational results used to help identify packages. The 'depguard quality score' sorting adds context but does not change the nature of the operation from retrieval to any higher-risk category.

From the tool's definition Tool performs search and retrieval of package information ('Search npm for packages by keywords') with sorting by quality metrics. No creation, modification, deletion, or execution of code occurs.

POLICY

How to control depguard_search

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_search:

policy.json

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

depguard_search 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.

How do I enforce a policy on depguard_search? +

Register the Depguard MCP server in PolicyLayer and add a rule for depguard_search: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Depguard. Nothing to install.

What risk level is depguard_search? +

Can I rate-limit depguard_search? +

Yes. Add a rate_limit block to the depguard_search rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block depguard_search completely? +

What MCP server provides depguard_search? +

depguard_search is provided by the Depguard MCP server (mopanc/depguard). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Depguard tool call.

Start from Depguard, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
