Retrieve detailed metadata about a file or directory. Returns comprehensive information including size, creation time, last modified time, permissions, and type.
AI agents call get_file_info 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 and queries file system metadata without side effects. It performs a read-only operation that does not create, modify, delete, or execute anything. The blast radius of misuse is minimal—an agent could enumerate file system structure and metadata, but cannot alter system state or trigger external operations.
From the tool's definition Tool name is 'get_file_info' and description states it 'Retrieve[s] detailed metadata about a file or directory' with no modification or deletion capability. Returns only informational data: 'size, creation time, last modified time, permissions, and type'.
Documented attack patterns abuse exactly the kind of access get_file_info 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 get_file_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_info": {}
}
}get_file_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve detailed metadata about a file or directory. Returns comprehensive information including size, creation time, last modified time, permissions, and type. 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 get_file_info: 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.
get_file_info 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_file_info 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_file_info. 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_file_info 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.
Free to start. No card required.
