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

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

## Why qsreplace_parameter_replacement is rated High

The description is empty, lowering confidence. However, qsreplace is a well-known security tool that replaces query string parameter values in URLs, typically used as part of fuzzing or injection attack pipelines. In the context of this offensive security server (pentesting, bug bounty automation), this tool likely executes parameter manipulation for vulnerability discovery.

From the tool's own definition: "Tool name 'qsreplace_parameter_replacement' suggests URL query string parameter replacement, commonly used in fuzzing/injection workflows. Server context is offensive security with 150+ cybersecurity tools for pentesting and bug bounty automation."

## Use case

AI agents invoke qsreplace_parameter_replacement to trigger actions in Hexstrike Ai. 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 Hexstrike Ai:

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