resistor_code
IEC 60062 resistor color code. Decode 3 to 6 bands, or encode a resistance that lands exactly on a digit-and-multiplier value. Digits run black=0 through white=9. Multipliers run from silver (×0.01) and gold (×0.1) through white (×1e9). Tolerances: brown 1%, red 2%, green 0.5%, blue 0.25%, violet...

What resistor_code does on ScorpTech x402 API
AI agents invoke resistor_code 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 |
|---|---|---|---|
ohms | string | — | Resistance to encode. Exact decimal or a fraction such as 47/10. |
bands | string | — | Colors, commas or spaces. Omit to encode ohms instead. |
count | integer | — | Bands when encoding. Default 4. Three bands are 20%. |
tempco | integer | — | ppm/K. Required for 6 bands, and only then. |
tolerance | string | — | Percent when encoding: 0.05, 0.1, 0.25, 0.5, 1, 2, 5, 10, or 20. Default 5% for 4 bands, 1% for 5 or 6, 20% for 3. |
Parameters from the server's own tool schema.
Why resistor_code is rated High
resistor_code 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 resistor_code 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 resistor_code, this is the rule to start with:
resistor_code 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 resistor_code call is checked against it from then on.
Questions about resistor_code
IEC 60062 resistor color code. Decode 3 to 6 bands, or encode a resistance that lands exactly on a digit-and-multiplier value. Digits run black=0 through white=9. Multipliers run from silver (×0.01) and gold (×0.1) through white (×1e9). Tolerances: brown 1%, red 2%, green 0.5%, blue 0.25%, violet 0.1%, grey 0.05%, gold 5%, silver 10%. Three bands mean 20% and have no tolerance band. The sixth band is the temperature coefficient in ppm/K: black 250, brown 100, red 50, orange 15, yellow 25, green 20, blue 10, violet 5, grey 1. Grey may be spelled gray. This does not measure a part. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: GET https://scorptech.it.com/api/x402/v1/resistor-code. 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.
resistor_code accepts 5 parameters: ohms, bands, count, tempco, tolerance. 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 resistor_code: 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.
resistor_code 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 resistor_code 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 resistor_code. 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.
resistor_code 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.
