Search for files containing a specific pattern.
AI agents call search_files to retrieve information from FastMCP Multi-Tool Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file search results based on a pattern match. It performs no data modification, deletion, or code execution—purely informational retrieval. Even if results include sensitive files, the tool itself has no side effects. Classified as Read with low severity due to minimal blast radius if misused by an agent.
From the tool's definition Tool name 'search_files' and description 'Search for files containing a specific pattern' indicate a query/search operation with no modification of data.

Search for files containing a specific pattern. It is categorised as a Read tool in the FastMCP Multi-Tool Server MCP Server, which means it retrieves data without modifying state.
Register the FastMCP Multi-Tool 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 FastMCP Multi-Tool 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 FastMCP Multi-Tool Server MCP server (rt0120-ramco/mcp-py). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
