## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why wavexis_service_worker_emulate is rated High

Emulating a service worker with a provided script URL constitutes code execution in a browser automation context. Service workers are powerful APIs that can intercept requests, manipulate responses, and run arbitrary JavaScript. An LLM agent given this tool could inject malicious service worker code, compromise request/response handling, or execute unintended operations.

From the tool's own definition: "Tool name contains 'emulate' and description states 'Emulate a service worker with a script URL.' Service workers are executable JavaScript contexts that intercept network requests and run custom logic."

## Use case

AI agents invoke wavexis_service_worker_emulate 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:
