Search for items in the Zotero literature database / the Zotero library, given a query string. The user may call this literature database, Zotero, Publications or similar.
AI agents call zotero_search_items to retrieve information from Zotero MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries data from a reference library without side effects. Searching a literature database is a classic Read operation. The severity is low because it only accesses existing reference metadata without ability to modify, delete, or execute operations. The confidence is high because the name and description clearly indicate a search/retrieval function.
From the tool's definition Tool performs 'Search for items in the Zotero literature database' with 'a query string' as input. This is a read-only retrieval operation with no modification, deletion, or execution of external code.

Search for items in the Zotero literature database / the Zotero library, given a query string. The user may call this literature database, Zotero, Publications or similar. It is categorised as a Read tool in the Zotero MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Zotero MCP Server MCP server in PolicyLayer and add a rule for zotero_search_items: 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 MCP Server. Nothing to install.
zotero_search_items 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 zotero_search_items 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 zotero_search_items. 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.
zotero_search_items is provided by the Zotero MCP Server MCP server (tspspi/zotero-mcp-postgres-ollama-fulltext). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
