## Why wavexis_activate_tab is rated High

Activating/focusing a browser tab is a browser action that triggers an external operation (changing the active tab in the browser), which falls under Execute. It has side effects on the browser state. Misuse could lead to unintended navigation or context switching, but blast radius is limited.

From the tool's own definition: "Activate (focus) a tab by its ID"

## Use case

AI agents invoke wavexis_activate_tab to trigger actions in Wavexis. 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Wavexis:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "wavexis_activate_tab": {
      "limits": [
        {
          "counter": "wavexis_activate_tab_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
