INPADOC patent family for a publication via EPO OPS — every worldwide equivalent of the same invention (same priority), each with country, document number, kind code, and combined publication number. Use it to find where a patent was also filed/granted globally. Net-new (no US-only equivalent).
AI agents call patents.epo-family to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries public patent information from the European Patent Office OPS (Online Patent Services) database and returns structured data about patent equivalents and filing jurisdictions. It has no side effects, does not modify or delete data, does not execute code, and does not involve financial transactions.
From the tool's definition Tool description states it retrieves patent family data 'for a publication' and is used to 'find where a patent was also filed/granted globally.' The verb 'retrieves' and the read-only nature of querying EPO OPS patent databases confirm no data modification,…

It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for patents.epo-family: 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 Mcp. Nothing to install.
patents.epo-family 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 patents.epo-family 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 patents.epo-family. 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.
