WHAT IT DOES

What alt_factorial does on ScorpTech x402 API

AI agents call alt_factorial to retrieve information from ScorpTech x402 API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`n`	integer	Yes

Parameters from the server's own tool schema.

RISK

Why alt_factorial is rated Low

Even though alt_factorial only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs alt_factorial safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ScorpTech x402 API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For alt_factorial, this is the rule to start with:

alt_factorial Allowed

alt_factorial is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "alt_factorial": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every alt_factorial call is checked against it from then on.

The alternating factorial af(n) = n! - (n-1)! + (n-2)! - ... ending at 1. af(1) is 1, af(3) is 5, and af(4) is 19. n runs from 1 to 200. Past 15 digits the value is a decimal string. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/alt-factorial. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.

What parameters does alt_factorial accept? +

alt_factorial accepts 1 parameter: n. Required: n. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on alt_factorial? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for alt_factorial: 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 ScorpTech x402 API. Nothing to install.

What risk level is alt_factorial? +

alt_factorial is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit alt_factorial? +

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

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

alt_factorial is provided by the ScorpTech x402 API MCP server (https://scorptech.it.com/api/x402/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
