AI agents call search_patent_law to retrieve information from Claude Patent Creator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search functions retrieve information without modifying, deleting, or executing code. In the context of a patent creation/analysis server, searching patent law regulations is a read-only operation with no blast radius from accidental misuse by an AI agent. The empty description lowers confidence slightly, but the explicit 'search_' prefix and domain context (patent law) make the read classification robust.
From the tool's definition Tool name 'search_patent_law' indicates retrieval/search functionality with no destructive or executable side effects. Description is empty, but naming convention strongly suggests query/read operations typical of legal research features in a patent system.
Documented attack patterns abuse exactly the kind of access search_patent_law gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Patent Creator, and nothing reaches the server without passing your rules. This is the rule we recommend for search_patent_law:
{
"version": "1",
"default": "deny",
"tools": {
"search_patent_law": {}
}
}search_patent_law is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
