biunitary_sigma
The sum of the bi-unitary divisors of n. For a prime power p^e the exponents run from 0 through e, skipping the middle one when e is even. 6 gives 12, 16 gives 27, 36 gives 50, and 48 gives 108. n runs from 1 to 1000000. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS:...

What biunitary_sigma does on ScorpTech x402 API
AI agents invoke biunitary_sigma to trigger actions in ScorpTech x402 API. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
n | integer | Yes |
Parameters from the server's own tool schema.
Why biunitary_sigma is rated High
biunitary_sigma triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs biunitary_sigma 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 biunitary_sigma, this is the rule to start with:
biunitary_sigma stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every biunitary_sigma call is checked against it from then on.
Questions about biunitary_sigma
The sum of the bi-unitary divisors of n. For a prime power p^e the exponents run from 0 through e, skipping the middle one when e is even. 6 gives 12, 16 gives 27, 36 gives 50, and 48 gives 108. n runs from 1 to 1000000. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/biunitary-sigma. It is categorised as a Execute tool in the ScorpTech x402 API MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
biunitary_sigma accepts 1 parameter: n. Required: n. The full parameter table on this page comes from the server's own tool schema.
Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for biunitary_sigma: 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.
biunitary_sigma is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the biunitary_sigma 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.
Set action: deny in the PolicyLayer policy for biunitary_sigma. 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.
biunitary_sigma 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.
