Search for files matching a pattern within allowed paths.
AI agents call search_files to retrieve information from Multi-Tool 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 about the filesystem (file locations matching patterns) without creating, modifying, or deleting data. It is confined to authorized paths, limiting its blast radius. The primary risk is information disclosure, which is inherent to any read operation and typically low severity unless the system contains highly sensitive data that should not be searched.
From the tool's definition Tool description states it 'Search[es] for files matching a pattern within allowed paths.' The verb 'search' and the scoping to 'allowed paths' indicate a read-only query operation with no side effects.
Attacks that exploit this kind of access
Search for files matching a pattern within allowed paths. It is categorised as a Read tool in the Multi-Tool MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Tool 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 Multi-Tool 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 Multi-Tool MCP Server MCP server (shawn-falconbury/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
