AI agents call find_similar to retrieve information from ZotSeek without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation against a Zotero library. It retrieves and returns matching results based on semantic similarity, with no side effects on the data. No creation, modification, deletion, code execution, or financial operations are involved. This is a straightforward information retrieval function.
From the tool's definition Tool name is 'find_similar' and description indicates it searches for papers similar to a library item. The verb 'find' and the semantic search nature (matching 'similar' papers) indicate retrieval/querying without modification.
Attacks that exploit this kind of access
Find papers similar to a known library item, using its stored. It is categorised as a Read tool in the ZotSeek MCP Server, which means it retrieves data without modifying state.
Register the ZotSeek MCP server in PolicyLayer and add a rule for find_similar: 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 ZotSeek. Nothing to install.
find_similar 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 find_similar 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 find_similar. 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.
find_similar is provided by the ZotSeek MCP server (introfini/ZotSeek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
