THE RISK

Low Risk

Why get_item_abstract needs a policy

This tool retrieves metadata (abstract/summary) from a Zotero item without modifying, deleting, or executing any operations. It is a straightforward read-only query function. Low severity because retrieving published abstracts poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'get_item_abstract' and description 'Get the abstract/summary of a specific item' indicate a retrieval operation with no side effects.

POLICY

How to control get_item_abstract

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 get_item_abstract:

policy.json

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

get_item_abstract 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.
