Get child items (attachments, notes) of a parent item. - Attachments include: PDF files, snapshots, linked files - Notes include: user-created notes attached to the item Use the returned attachment key with download_attachment to get the file.
AI agents call get_item_children to retrieve information from Zotero without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing data (child items, attachments, and notes) from a Zotero reference without modifying, deleting, or executing operations. It is purely informational—returning metadata that can then be used with other tools like download_attachment. This is a read-only query operation with minimal blast radius even if called incorrectly by an AI agent.
From the tool's definition Tool description explicitly states it 'Get[s] child items (attachments, notes)' and retrieves metadata about attachments and notes. The description indicates this is a query/retrieval operation with no modification or deletion of data.

It is categorised as a Read tool in the Zotero MCP Server, which means it retrieves data without modifying state.
Register the Zotero MCP server in PolicyLayer and add a rule for get_item_children: 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 Zotero. Nothing to install.
get_item_children is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_item_children 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.
Set action: deny in the PolicyLayer policy for get_item_children. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_item_children is provided by the Zotero MCP server (xbghc/zotero-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
