Get database statistics and aggregations for strategic planning.
AI agents call get_citation_statistics to retrieve information from USPTO Patent Citation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves aggregate data and statistics from a patent citation database without creating, modifying, deleting, or executing any operations. It is purely a read operation with minimal blast radius if misused by an AI agent, as the worst outcome would be accessing statistics that provide no direct control over systems or data modification.
From the tool's definition Tool returns 'database statistics and aggregations' with no indication of modification, deletion, or execution. The verb 'Get' and the informational purpose ('strategic planning') align with retrieval-only operations.
Documented attack patterns abuse exactly the kind of access get_citation_statistics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and USPTO Patent Citation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_citation_statistics:
{
"version": "1",
"default": "deny",
"tools": {
"get_citation_statistics": {}
}
}get_citation_statistics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get database statistics and aggregations for strategic planning. It is categorised as a Read tool in the USPTO Patent Citation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the USPTO Patent Citation MCP Server MCP server in PolicyLayer and add a rule for get_citation_statistics: 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 USPTO Patent Citation MCP Server. Nothing to install.
get_citation_statistics 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 get_citation_statistics 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 get_citation_statistics. 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.
get_citation_statistics is provided by the USPTO Patent Citation MCP Server MCP server (john-walkoe/uspto_enriched_citation_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from USPTO Patent Citation MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
