Find files by name pattern, extension, or other criteria
AI agents call find_files to retrieve information from MCP Workspace Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs file discovery and listing operations, which are inherently non-destructive queries. It retrieves information about files matching specified criteria but does not create, modify, delete, or execute any code. The sandboxed workspace context further constrains its blast radius. Confidence is high because the description unambiguously indicates a read-only operation.
From the tool's definition 'Find files by name pattern, extension, or other criteria' describes a search/query operation that retrieves file metadata without modifying, deleting, or executing anything. The description explicitly limits the tool to finding/locating files.
Attacks that exploit this kind of access
Find files by name pattern, extension, or other criteria. It is categorised as a Read tool in the MCP Workspace Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Workspace Server MCP server in PolicyLayer and add a rule for find_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 MCP Workspace Server. Nothing to install.
find_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 find_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 find_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.
find_files is provided by the MCP Workspace Server MCP server (shayyeffet/ultimate_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
