List files that would be searched by ripgrep without actually searching them
AI agents call list-files to retrieve information from Mcp Ripgrep without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays file metadata/names only. It performs no search operations, makes no modifications to files or systems, and has no destructive or financial implications. The impact is informational only, making it a safe Read operation with minimal security risk.

Attacks that exploit this kind of access
List files that would be searched by ripgrep without actually searching them. It is categorised as a Read tool in the Mcp Ripgrep MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ripgrep 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 Ripgrep. 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 Ripgrep MCP server (mcp-ripgrep). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
