Recursively search for files and directories matching a pattern. Searches through all subdirectories from the starting path. The search is case-sensitive and matches partial names.
AI agents call search_files to retrieve information from Wuying AgentBay without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about files and directories without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an agent could discover sensitive file locations but cannot access, modify, or execute them. Classification as Read is appropriate for information retrieval with no side effects.
From the tool's definition Tool performs recursive file search matching a pattern with no modification, deletion, or execution capabilities. Description states it 'search for files and directories' with pattern matching—a read-only query operation.
Documented attack patterns abuse exactly the kind of access search_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wuying AgentBay, and nothing reaches the server without passing your rules. This is the rule we recommend for search_files:
{
"version": "1",
"default": "deny",
"tools": {
"search_files": {}
}
}search_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Recursively search for files and directories matching a pattern. Searches through all subdirectories from the starting path. The search is case-sensitive and matches partial names. It is categorised as a Read tool in the Wuying AgentBay MCP Server, which means it retrieves data without modifying state.
Register the Wuying AgentBay MCP server in PolicyLayer and add a rule for search_files: 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 Wuying AgentBay. Nothing to install.
search_files 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_files 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_files. 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_files is provided by the Wuying AgentBay MCP server (michael98671/agentbay). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wuying AgentBay, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
