WHAT IT DOES

What crc16 does on ScorpTech x402 API

AI agents call crc16 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
`hex`	string	—
`text`	string	—
`algorithm`	string	—

Parameters from the server's own tool schema.

RISK

Why crc16 is rated Low

Even though crc16 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

RECOMMENDED RULE

The rule that runs crc16 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 crc16, this is the rule to start with:

crc16 Allowed

crc16 is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "crc16": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every crc16 call is checked against it from then on.

FAQ

Questions about crc16

What does the crc16 tool do? +

CRC-16 over text or hex bytes. Algorithms are CCITT-FALSE, ARC, XMODEM, KERMIT and MODBUS. The check string 123456789 is 29b1 in CCITT-FALSE. This is not CRC-32. Price: $0.001 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/crc16. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.

What parameters does crc16 accept? +

crc16 accepts 3 parameters: hex, text, algorithm. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on crc16? +

Register the ScorpTech x402 API MCP server in PolicyLayer and add a rule for crc16: 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.

What risk level is crc16? +

crc16 is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit crc16? +

Yes. Add a rate_limit block to the crc16 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.

How do I block crc16 completely? +

Set action: deny in the PolicyLayer policy for crc16. 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.

What MCP server provides crc16? +

crc16 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.
