AI agents call search_designs to retrieve information from Marka Patent MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations that query a patent/trademark database for information retrieval are Read category — they retrieve data with no side effects. The empty description lowers confidence slightly, but the sibling tools and server's stated purpose (search and retrieve) confirm this is a data retrieval tool. Severity is low because misuse poses no direct harm — worst case is unwanted information access.
From the tool's definition Tool name 'search_designs' indicates a search operation. Sibling tools (search_patents, search_trademarks) are clearly Read operations retrieving data from TÜRKPATENT database.
Documented attack patterns abuse exactly the kind of access search_designs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Marka Patent MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_designs:
{
"version": "1",
"default": "deny",
"tools": {
"search_designs": {}
}
}search_designs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

search_designs. It is categorised as a Read tool in the Marka Patent MCP MCP Server, which means it retrieves data without modifying state.
Register the Marka Patent MCP server in PolicyLayer and add a rule for search_designs: 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 Marka Patent MCP. Nothing to install.
search_designs 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_designs 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_designs. 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_designs is provided by the Marka Patent MCP server (saidsurucu/markapatent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
