Identify which frameworks, libraries, CMS, analytics, and hosting a website uses
AI agents call detect_tech_stack to retrieve information from ToolCenter MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes publicly available technical information about a website's technology stack. It performs no modifications, deletions, code execution, or financial operations. The information gathered is already publicly visible through browser inspection, HTTP headers, and other passive reconnaissance techniques.
From the tool's definition The tool 'detect_tech_stack' is described as identifying (passive reconnaissance) frameworks, libraries, CMS, analytics, and hosting used by a website.
Attacks that exploit this kind of access
Identify which frameworks, libraries, CMS, analytics, and hosting a website uses. It is categorised as a Read tool in the ToolCenter MCP MCP Server, which means it retrieves data without modifying state.
Register the ToolCenter MCP server in PolicyLayer and add a rule for detect_tech_stack: 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 ToolCenter MCP. Nothing to install.
detect_tech_stack 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 detect_tech_stack 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 detect_tech_stack. 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.
detect_tech_stack is provided by the ToolCenter MCP server (toolcenter-dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
