AI agents call tech_stack to retrieve information from APIMesh 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 and analyzes publicly available technical information about websites through HTTP headers and HTML inspection. It has no capability to modify, execute code on, or damage target systems. The data returned is informational reconnaissance only. While it could be used for reconnaissance in an attack, the tool itself performs only read operations.
From the tool's definition Tool "detects technologies from HTTP headers and HTML" - performs analysis and identification without modifying data. Description emphasizes detection and analysis with no mention of writing, executing, or deleting operations.

It is categorised as a Read tool in the APIMesh MCP Server MCP Server, which means it retrieves data without modifying state.
Register the APIMesh MCP Server MCP server in PolicyLayer and add a rule for 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 APIMesh MCP Server. Nothing to install.
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 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 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.
tech_stack is provided by the APIMesh MCP Server MCP server (mbeato/apimesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
