AI agents call list_key_files to retrieve information from QoutaMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs inspection and analysis of project files to identify entry points, configuration files, and documentation. It retrieves information about the project structure but does not execute code, modify files, delete data, or trigger external operations. The action is purely informational and has no side effects on the system or codebase.
From the tool's definition Tool lists and categorizes key files in a project structure. The description uses 'list' and 'categorized by purpose', indicating retrieval and inspection of existing project metadata without modification, deletion, or execution.
Attacks that exploit this kind of access
List key files in a project, categorized by purpose: entry points, config files, and documentation. It is categorised as a Read tool in the QoutaMCP MCP Server, which means it retrieves data without modifying state.
Register the Qouta MCP server in PolicyLayer and add a rule for list_key_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 QoutaMCP. Nothing to install.
list_key_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 list_key_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 list_key_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.
list_key_files is provided by the Qouta MCP server (qoutaid/qoutamcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
