Search within full-text content of all documents. Returns matching passages with context. Use get_content with itemKey for complete text of a result.
AI agents call search_fulltext to retrieve information from Zotero Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs full-text search across documents and returns matching passages—a typical information retrieval operation with no side effects. It does not create, modify, delete, or execute any external operations.
From the tool's definition The tool description explicitly states it "Search[es] within full-text content of all documents. Returns matching passages with context." This is a read-only query operation that retrieves and displays search results without modifying any data.

Search within full-text content of all documents. Returns matching passages with context. Use get_content with itemKey for complete text of a result. It is categorised as a Read tool in the Zotero Agent MCP Server, which means it retrieves data without modifying state.
Register the Zotero Agent MCP server in PolicyLayer and add a rule for search_fulltext: 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 Agent. Nothing to install.
search_fulltext 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 search_fulltext 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 search_fulltext. 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.
search_fulltext is provided by the Zotero Agent MCP server (psiQAQ/zotero-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
search_fulltext is one line of Zotero Agent's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
