Returns a list of files as ResourceLinks without embedding their content
AI agents call list-files to retrieve information from MCP-TS-DEMO without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves file metadata/paths without modifying, deleting, or executing anything. It does not alter state and poses minimal security risk even if misused by an AI agent, since it only provides information about files rather than their contents or permissions to modify them.
From the tool's definition The tool "list-files" returns a list of files as ResourceLinks without embedding their content. The description explicitly indicates data retrieval with no side effects.
Attacks that exploit this kind of access
Returns a list of files as ResourceLinks without embedding their content. It is categorised as a Read tool in the MCP-TS-DEMO MCP Server, which means it retrieves data without modifying state.
Register the MCP-TS-DEMO 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 MCP-TS-DEMO. 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 MCP-TS-DEMO MCP server (pjqdyd/mcp-ts-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
