AI agents call get_files_touched to retrieve information from Yocoolab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool returns metadata about files touched in Claude Code sessions. It retrieves and queries historical data without creating, modifying, deleting, or executing anything. While it exposes information about code changes, the tool itself performs no side effects — it only lists paths and counts. This is a straightforward Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'List all files that have been read, written, or edited' and 'Shows file paths with session counts' — this is purely informational retrieval about file activity history, not modification of files or sessions themselves.

Attacks that exploit this kind of access
List all files that have been read, written, or edited across Claude Code sessions. Shows file paths with session counts. It is categorised as a Read tool in the Yocoolab MCP Server, which means it retrieves data without modifying state.
Register the Yocoolab MCP server in PolicyLayer and add a rule for get_files_touched: 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 Yocoolab. Nothing to install.
get_files_touched 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_files_touched 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_files_touched. 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_files_touched is provided by the Yocoolab MCP server (yocoolab/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
