Bibliographic record for a patent publication via EPO OPS: invention titles (multiple languages), applicants, inventors, IPC classifications, application number, and the abstract. Worldwide coverage by publication number (e.g. EP1000000, US6093011). Net-new vs US-only patents.detail.
AI agents call patents.epo-biblio 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.
The tool retrieves read-only bibliographic metadata about patents (titles, inventors, applicants, classifications, abstracts) from the EPO OPS database. There are no side effects, modifications, deletions, or financial transactions. It is a pure data retrieval operation. Severity is low as misuse would only expose publicly available patent information.

Bibliographic record for a patent publication via EPO OPS: invention titles (multiple languages), applicants, inventors, IPC classifications, application number, and the abstract. Worldwide coverage by publication number (e.g. EP1000000, US6093011). Net-new vs US-only patents.detail. 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-biblio: 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-biblio 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-biblio 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-biblio. 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.
patents.epo-biblio is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
