AI agents call search to retrieve information from YiGmMk/mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries search engine results without creating, modifying, deleting, or executing operations. It is purely informational and read-only in nature. The low severity reflects minimal blast radius if misused—an agent could only retrieve publicly available search data.
From the tool's definition Tool performs web search using s.jina.ai and returns SERP results with URLs and content in text format. Description states it 'searches the network and returns top five results' (搜索网络并返回前五个结果) with no mention of modification, deletion, or execution…
Documented attack patterns abuse exactly the kind of access search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and YiGmMk/mcp, and nothing reaches the server without passing your rules. This is the rule we recommend for search:
{
"version": "1",
"default": "deny",
"tools": {
"search": {}
}
}search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the YiGmMk/ MCP server in PolicyLayer and add a rule for search: 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 YiGmMk/mcp. Nothing to install.
search 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 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. 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 is provided by the YiGmMk/ MCP server (yigmmk/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from YiGmMk/mcp, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
