WHAT IT DOES

What stern does on ScorpTech x402 API

AI agents call stern 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
`mod`	string	—

Parameters from the server's own tool schema.

RISK

Why stern is rated Low

Even though stern 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 stern 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 stern, this is the rule to start with:

stern Allowed

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

View as policy code

policy.json

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

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 stern call is checked against it from then on.

FAQ

Questions about stern

What does the stern tool do? +

Stern's diatomic sequence. s(0) is 0, s(1) is 1, even terms repeat s(n/2), and an odd term is the sum of its two neighbors in the previous row. An optional modulus reduces the term; zero is rejected. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/stern. 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 stern accept? +

stern accepts 2 parameters: n, mod. Required: n. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on stern? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for stern: 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 stern? +

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

Can I rate-limit stern? +

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

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

stern 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.
