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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "generate_and_execute_test",
    "arguments": {}
  }
}
```

## Why generate_and_execute_test is rated High

This tool generates test cases and immediately runs them, meaning arbitrary browser automation actions (clicks, form fills, navigation) and code execution occur. The 'immediately execute' aspect means an AI agent could trigger unintended side effects across web applications without human review of the generated test. This spans Write and Execute categories; Execute is the most severe applicable.

From the tool's own definition: "'Generate and immediately execute a test case' — the tool both generates and executes test code immediately, triggering browser automation actions and external operations"

## Use case

AI agents invoke generate_and_execute_test to trigger actions in Percepta MCP Server. 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 Percepta MCP Server:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "generate_and_execute_test": {
      "limits": [
