search_citations_minimal
AI agents call search_citations_minimal 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.
The tool is part of a patent citation analysis server and performs search operations on citation data. 'Search' operations are fundamentally read operations that retrieve and query existing data without modification, deletion, or execution of arbitrary code. The 'minimal' suffix suggests it returns a reduced dataset, consistent with read-only retrieval.
From the tool's definition Tool name 'search_citations_minimal' with 'search' prefix indicates data retrieval. Sibling tools like 'search_citations_balanced' and 'search_oa_citations_balanced' on a patent citation analysis server confirm read-only query operations.
Documented attack patterns abuse exactly the kind of access search_citations_minimal 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 search_citations_minimal:
{
"version": "1",
"default": "deny",
"tools": {
"search_citations_minimal": {}
}
}search_citations_minimal is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
search_citations_minimal. 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 search_citations_minimal: 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.
search_citations_minimal 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 search_citations_minimal 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 search_citations_minimal. 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.
search_citations_minimal 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.
