WHAT IT DOES

What navigate does on 4bis Relay Showcase

AI agents invoke navigate to trigger actions in 4bis Relay Showcase. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why navigate is rated High

Tool navigates to arbitrary URLs, triggering external HTTP requests whose effects depend on target.

From the tool's definition Navega a una URL (navigate to URL); external network request with side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs navigate safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 4bis Relay Showcase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For navigate, this is the rule to start with:

navigate Rate-limited

navigate stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

          "window": "minute",
          "max": 10,

        }
      ]
    }
  }
}
