AI agents call list_supported_tools to retrieve information from AI Diagram & Prototype Generator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns information about available tools and supported features. It is a read-only operation that queries the system's capabilities and returns data to the user without modifying, executing, or affecting any resources. No data is created, modified, or deleted.
From the tool's definition Tool name is 'list_supported_tools' and description indicates it displays a list of capabilities: '展示能力列表' (show capability list).
Documented attack patterns abuse exactly the kind of access list_supported_tools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AI Diagram & Prototype Generator, and nothing reaches the server without passing your rules. This is the rule we recommend for list_supported_tools:
{
"version": "1",
"default": "deny",
"tools": {
"list_supported_tools": {}
}
}list_supported_tools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the AI Diagram & Prototype Generator MCP server in PolicyLayer and add a rule for list_supported_tools: 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 AI Diagram & Prototype Generator. Nothing to install.
list_supported_tools 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 list_supported_tools 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 list_supported_tools. 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.
list_supported_tools is provided by the AI Diagram & Prototype Generator MCP server (simonutd/ai-diagram-prototype-generator-mcp-server-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
