voltage_divider
Unloaded voltage divider. r1 is the top resistor, from the supply to the output. r2 is the bottom resistor, from the output to ground. Returns the output voltage, the string current, and the power in each resistor as exact rationals. Both resistors must be positive. A zero supply gives zero outpu...

What voltage_divider does on ScorpTech x402 API
AI agents call voltage_divider 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 |
|---|---|---|---|
r1 | string | Yes | Top resistor, ohms |
r2 | string | Yes | Bottom resistor, ohms |
vin | string | Yes | Supply voltage, volts |
Parameters from the server's own tool schema.
Why voltage_divider is rated Low
Even though voltage_divider 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 voltage_divider 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 voltage_divider, this is the rule to start with:
voltage_divider 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 voltage_divider call is checked against it from then on.
Questions about voltage_divider
Unloaded voltage divider. r1 is the top resistor, from the supply to the output. r2 is the bottom resistor, from the output to ground. Returns the output voltage, the string current, and the power in each resistor as exact rationals. Both resistors must be positive. A zero supply gives zero output, zero current and zero power. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/voltage-divider. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
voltage_divider accepts 3 parameters: r1, r2, vin. Required: r1, r2, vin. 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 voltage_divider: 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.
voltage_divider 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 voltage_divider 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 voltage_divider. 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.
voltage_divider 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.
