List files in a directory. Argument: path (default '.')
AI agents call list_files to retrieve information from Aurora-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a directory listing, which is a passive query operation with no side effects. It retrieves information about filesystem structure but does not create, modify, delete, or execute anything.
From the tool's definition Tool name is 'list_files' and description states 'List files in a directory' — a read-only operation that retrieves directory contents without modification or execution.
Attacks that exploit this kind of access
List files in a directory. Argument: path (default '.'). It is categorised as a Read tool in the Aurora-MCP MCP Server, which means it retrieves data without modifying state.
Register the Aurora- MCP server in PolicyLayer and add a rule for list_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 Aurora-MCP. Nothing to install.
list_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_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_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_files is provided by the Aurora- MCP server (ndaniel/aurora-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
