Check for file changes by comparing current files with a manifest (for gallery refresh integration)
AI agents call superdesign_check_files to retrieve information from Superdesign MCP 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 inspection and comparison against a manifest for gallery refresh purposes. It retrieves and analyzes data (current files vs. manifest) to detect changes, but does not modify, delete, execute, or create any files. The operation is purely observational with no side effects beyond returning comparison results. Classified as Read with low severity due to its benign, query-only nature.
From the tool's definition Tool description states 'Check for file changes by comparing current files with a manifest' — a read-only comparison operation that retrieves and queries file state without modification.
Documented attack patterns abuse exactly the kind of access superdesign_check_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Superdesign MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for superdesign_check_files:
{
"version": "1",
"default": "deny",
"tools": {
"superdesign_check_files": {}
}
}superdesign_check_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check for file changes by comparing current files with a manifest (for gallery refresh integration). It is categorised as a Read tool in the Superdesign MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Superdesign MCP Server MCP server in PolicyLayer and add a rule for superdesign_check_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 Superdesign MCP Server. Nothing to install.
superdesign_check_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 superdesign_check_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 superdesign_check_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.
superdesign_check_files is provided by the Superdesign MCP Server MCP server (jonthebeef/superdesign-mcp-claude-code). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Superdesign MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
