What license_detect does on ScorpTech x402 API
AI agents call license_detect 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 |
|---|---|---|---|
spdx | string | — | Or an SPDX licence expression, e.g. "MIT OR Apache-2.0", "GPL-2.0-or-later WITH Classpath-exception-2.0" |
text | string | — | LICENSE / COPYING text, README section or source file header |
Parameters from the server's own tool schema.
Why license_detect is rated Low
Even though license_detect 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 license_detect 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 license_detect, this is the rule to start with:
license_detect 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 license_detect call is checked against it from then on.
Questions about license_detect
Identify a software / content licence from a LICENSE file, source header or SPDX expression and explain what it allows: 40 licences incl. MIT, Apache-2.0, BSD-2/3/4, ISC, 0BSD, GPL/LGPL/AGPL v2/v3, MPL-2.0, EPL, EUPL, Unlicense, CC0, Creative Commons BY/SA/NC/ND, and source-available BUSL / SSPL / Elastic / PolyForm / Commons Clause. Returns SPDX id, confidence, category (permissive, weak / strong / network copyleft, non-commercial, source-available), OSI approval, permissions / conditions / limitations, "or later" detection, SPDX-License-Identifier tags and copyright holders. Offline; not legal advice. Price: $0.002 USDC per successful call (x402, Solana). Same tool over HTTPS: POST https://scorptech.it.com/api/x402/v1/license-detect. It is categorised as a Read tool in the ScorpTech x402 API MCP Server, which means it retrieves data without modifying state.
license_detect accepts 2 parameters: spdx, text. 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 license_detect: 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.
license_detect 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 license_detect 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 license_detect. 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.
license_detect 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.
