WHAT IT DOES

What http_replay does on Kali Security MCP

AI agents invoke http_replay to trigger actions in Kali Security MCP. 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 http_replay is rated High

This tool replays HTTP requests with the ability to modify parameters, which actively triggers external HTTP operations against target systems. In a penetration testing context, replaying and modifying HTTP requests constitutes an active operation (not just reading) that can probe, exploit, or manipulate web applications.

RECOMMENDED RULE

The rule that runs http_replay safely

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

http_replay Rate-limited

http_replay 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "http_replay": {
      "limits": [
        {
          "counter": "http_replay_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

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

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

FAQ

Questions about http_replay

What does the http_replay tool do? +

重放历史HTTP请求，可修改参数. It is categorised as a Execute tool in the Kali Security MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on http_replay? +

Register the Kali Security MCP server in PolicyLayer and add a rule for http_replay: 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 Kali Security MCP. Nothing to install.

What risk level is http_replay? +

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

Can I rate-limit http_replay? +

Yes. Add a rate_limit block to the http_replay 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 http_replay completely? +

Set action: deny in the PolicyLayer policy for http_replay. 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 http_replay? +

http_replay is provided by the Kali Security MCP server (seac-25/kali-security-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
