Why get_quota_status needs a policy

This tool queries the status of API quotas—a purely informational retrieval with no side effects. It does not create, modify, delete, execute code, or commit financial resources. The blast radius of misuse is minimal (exposure of quota/usage information only).

From the tool's definition Tool name 'get_quota_status' and description 'Check current Elsevier API quota status' indicate a read-only query operation that retrieves metadata about API usage without modifying, executing, or deleting anything.

POLICY

How to control get_quota_status

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

policy.json

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

get_quota_status 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 UniArticles 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.
