WHAT IT DOES

What switchTab does on Nodebench

AI agents invoke switchTab to trigger actions in Nodebench. 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 switchTab is rated High

Switching tabs triggers a UI/navigation action in the research hub, which is an external operation/browser-like action rather than a simple read or write. The description is vague about side effects, so confidence is moderate. Severity is medium as misuse could disrupt workflow state but has limited blast radius.

RECOMMENDED RULE

The rule that runs switchTab safely

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

switchTab Rate-limited

switchTab 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.

    "switchTab": {
      "limits": [
        {
          "counter": "switchtab_rate",
          "window": "minute",
          "max": 10,

        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every switchTab call is checked against it from then on.

FAQ

Questions about switchTab

What does the switchTab tool do? +

Switch between research hub tabs. It is categorised as a Execute tool in the Nodebench MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on switchTab? +

Register the Nodebench MCP server in PolicyLayer and add a rule for switchTab: 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 Nodebench. Nothing to install.

What risk level is switchTab? +

switchTab is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit switchTab? +

Yes. Add a rate_limit block to the switchTab 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.

How do I block switchTab completely? +

Set action: deny in the PolicyLayer policy for switchTab. 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.

What MCP server provides switchTab? +

switchTab is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
