prufer_degree
The degree of a vertex in the tree described by a Prüfer code. Degree is one plus the number of times the vertex appears. In code 2,3, vertex 2 has degree 2 and vertex 1 has degree 1. The vertex must lie from 1 to n. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POS...

What prufer_degree does on ScorpTech x402 API
AI agents call prufer_degree 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 |
|---|---|---|---|
code | array | Yes | |
vertex | integer | Yes |
Parameters from the server's own tool schema.
Why prufer_degree is rated Low
Even though prufer_degree 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.

The rule that runs prufer_degree 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 prufer_degree, this is the rule to start with:
prufer_degree 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 prufer_degree call is checked against it from then on.
Questions about prufer_degree
The degree of a vertex in the tree described by a Prüfer code. Degree is one plus the number of times the vertex appears. In code 2,3, vertex 2 has degree 2 and vertex 1 has degree 1. The vertex must lie from 1 to n. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/prufer-degree. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
prufer_degree accepts 2 parameters: code, vertex. Required: code, vertex. 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 prufer_degree: 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.
prufer_degree 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 prufer_degree 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 prufer_degree. 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.
prufer_degree 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.
