MOST DANGEROUS TOOLS

Critical Risk

The most dangerous GotFreeFax tools

Financial · Critical purchase_credits This tool initiates a real financial transaction via PayPal to purchase prepaid credits. Financial · High send_fax While the tool itself sends a fax, the server context makes clear this is a paid service where sending faxes consumes purchased credits. Write · Medium send_free_fax The tool sends a fax (an external communication), which is a Write action — it creates an outbound message to a third party.

3 of GotFreeFax's 7 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control GotFreeFax

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

Block financial tools by default

{
  "purchase_credits": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Rate limit write operations

{
  "send_free_fax": {
    "limits": [
      {
        "counter": "send_free_fax_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "check_fax_status": {
    "limits": [
      {
        "counter": "check_fax_status_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 GotFreeFax — 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 GotFreeFax

Can an AI agent move money through the GotFreeFax MCP server? +

Yes. The GotFreeFax server exposes 2 financial tools including purchase_credits, send_fax. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.

How do I prevent bulk modifications through GotFreeFax? +

The GotFreeFax server has 1 write tools including send_free_fax. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach GotFreeFax.

7 tools across 3 categories: Execute, Read, Write. 4 are read-only. 3 can modify, create, or delete data.

How do I enforce a policy on GotFreeFax? +

Register the GotFreeFax 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.
