AI agents call get_patent_bigquery 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.
BigQuery 'get' operations are inherently read-only; they retrieve data without modifying or deleting it. However, the severity is elevated to 'medium' because patent databases may contain sensitive intellectual property information, commercially sensitive filing details, or personal information about inventors. Unauthorized access to such data could cause competitive harm or privacy violations.
From the tool's definition Tool name 'get_patent_bigquery' indicates querying a BigQuery database (a read operation). The server context shows patent-related data retrieval. The description is empty, which reduces confidence slightly.

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 get_patent_bigquery:
{
"version": "1",
"default": "deny",
"tools": {
"get_patent_bigquery": {}
}
