MOST DANGEROUS TOOLS

High Risk

The most dangerous Rfhub tools

Execute · Low arfcn_calculator_4g_compute This tool performs frequency-to-channel-number conversions for 4G LTE networks and displays band details.

1 of Rfhub'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 Rfhub

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

Cap read operations

{
  "arfcn_calculator_5g_compute": {
    "limits": [
      {
        "counter": "arfcn_calculator_5g_compute_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 Rfhub — 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 Rfhub

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

The Rfhub 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 Rfhub 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 Rfhub? +

Register the Rfhub 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 Rfhub tool call.

Deterministic rules across all 3 Rfhub tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
