unitary_sigma
The sum of the unitary divisors of n. A unitary divisor shares no prime factor with the complementary divisor. The sum is 1 for 1, 12 for 6, 20 for 12, and 72 for 30. n runs from 1 to 1000000000000.

What unitary_sigma does on ScorpTech x402 API
AI agents call unitary_sigma 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 |

Why unitary_sigma is rated Low
Even though unitary_sigma 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
The rule that runs unitary_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 unitary_sigma, this is the rule to start with:
unitary_sigma is read-only, so it stays allowed. 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 unitary_sigma call is checked against it from then on.
Questions about unitary_sigma
The sum of the unitary divisors of n. A unitary divisor shares no prime factor with the complementary divisor. The sum is 1 for 1, 12 for 6, 20 for 12, and 72 for 30. n runs from 1 to 1000000000000. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/unitary-sigma. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
unitary_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 unitary_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.
unitary_sigma is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the unitary_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 unitary_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.
unitary_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.
