What list_middlewares does on Traefik MCP Server

AI agents call list_middlewares to retrieve information from Traefik MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_middlewares needs a policy

This tool retrieves information about Traefik middlewares without modifying, executing, or deleting any configurations. However, middleware details could reveal security-sensitive information (authentication rules, rate limiting policies, headers manipulation), justifying medium severity for a read operation. The confidence is high because the description unambiguously describes a listing/query action.

From the tool's definition Tool name 'list_middlewares' and description 'List all HTTP middlewares in Traefik' indicate a query/retrieval operation with no modification or execution of configurations.
