Search for text within files
AI agents call search_files to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information by searching file contents but does not create, modify, delete, or execute anything. It is purely informational and has minimal risk even if misused by an AI agent, as it only returns matching text patterns.
From the tool's definition Tool name is 'search_files' and description states 'Search for text within files' — this is a query/search operation with no side effects or data modification.
Attacks that exploit this kind of access
Search for text within files. It is categorised as a Read tool in the Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced MCP Server MCP server in PolicyLayer and add a rule for search_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 Enhanced MCP Server. Nothing to install.
search_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 search_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 search_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.
search_files is provided by the Enhanced MCP Server MCP server (jacobcdsmith/mcp-commander-console). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
