MOST DANGEROUS TOOLS

High Risk

The most dangerous Nuclei tools

Execute · Critical nuclei_scan Nuclei is an active vulnerability scanner that executes network probes, HTTP requests, and exploit attempts against target systems.

1 of Nuclei's 3 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Nuclei

PolicyLayer is an MCP gateway — it sits between your AI agents and Nuclei, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations

{
  "check_scope": {
    "limits": [
      {
        "counter": "check_scope_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register Nuclei — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Nuclei

Is the Nuclei MCP server safe to use without restrictions? +

The Nuclei server is primarily read-only with 2 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the Nuclei MCP server expose? +

3 tools across 1 categories: Read. 2 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on Nuclei? +

Register the Nuclei MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Nuclei tool call.
