Why list-container-registry-auths needs a policy

The tool performs a read operation to enumerate container registry authentication entries. While the description is empty, the naming convention and context within the Novita AI platform management server clearly indicates this is a non-destructive query operation. Similar to 'list' or 'get' operations, it retrieves data without side effects.

From the tool's definition Tool name 'list-container-registry-auths' indicates a listing/retrieval operation. No description provided, but the 'list' prefix and pattern matching sibling tools (create/delete variants exist for this resource) strongly suggest this retrieves container…

POLICY

How to control list-container-registry-auths

PolicyLayer is an MCP gateway — it sits between your AI agents and Novita MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-container-registry-auths:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-container-registry-auths": {}
  }
}

list-container-registry-auths 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 Novita MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
