Search for content within files using regex or text matching
AI agents call search_files to retrieve information from Enhanced Directory Context 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 and queries file contents to locate matching patterns. It does not create, modify, delete, or execute code; it only reads and searches. Even though the server offers destructive operations (delete_file, batch_file_operations), this specific tool is limited to search—the least severe category.
From the tool's definition Tool performs 'search for content within files' with regex or text matching—a query operation with no modification or deletion of data. The description explicitly indicates retrieval only, with no side effects.
Attacks that exploit this kind of access
Search for content within files using regex or text matching. It is categorised as a Read tool in the Enhanced Directory Context MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced Directory Context 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 Directory Context 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 Directory Context MCP Server MCP server (pwalagov/file-control-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
