THE RISK

Low Risk

Why search_collections needs a policy

This tool performs a search query on collections in Zotero by name, which is a read-only operation that retrieves information without side effects. No data is created, modified, deleted, or executed. The low severity reflects minimal risk if misused—an agent could retrieve collection names but cannot alter the system.

From the tool's definition Tool name 'search_collections' with description 'Search collections by name' indicates a query/search operation with no modification or deletion of data.

POLICY

How to control search_collections

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

policy.json

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

search_collections 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 Zotero — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
