AI agents call law.trademark-status 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 is a straightforward data retrieval tool that queries the US Patent and Trademark Office database by serial or registration number. It returns read-only information (status, dates, owner, mark type, classes) without modifying any state. The pay-per-call settlement mechanism via x402/USDC is payment for API access, not a financial operation performed by the tool itself.
From the tool's definition Tool retrieves trademark status data from USPTO TSDR via number lookup. Description indicates it "Verify", "confirm", and provides "real-time" data about mark status, owner, classes—all query operations with no side effects.

Verify a US trademark by USPTO serial number (8 digits) or registration number: word mark, LIVE/DEAD status with detail and dates, current owner, mark type, and international classes covered. Authoritative real-time USPTO TSDR data — confirm a mark exists and is active instead of trusting model memory. Number lookup only (no text search). 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 law.trademark-status: 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.

Yes. Add a rate_limit block to the law.trademark-status 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 law.trademark-status. 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.
