WHAT IT DOES

What proxy_add_rule does on Kali Security MCP

AI agents use proxy_add_rule to create or update resources in Kali Security MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kali Security MCP environment.

RISK

Why proxy_add_rule is rated Medium

The name 'proxy_add_rule' suggests the tool creates or adds a new rule to a proxy configuration. In the context of a penetration testing/security server, this likely modifies proxy intercept or routing rules, which is a Write-level operation. However, since the description is empty, confidence is low.

From the tool's definition Tool name: proxy_add_rule; description is empty and uninformative.

proxy_add_rule Rate-limited

proxy_add_rule stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
