WHAT IT DOES

What selector_specificity does on ScorpTech x402 API

RECOMMENDED RULE

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

selector_specificity Rate-limited

selector_specificity stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about selector_specificity

What does the selector_specificity tool do? +

Specificity of one CSS selector, from Selectors Level 4. a is IDs. b is classes, attributes and pseudo-classes. c is elements and pseudo-elements. :is(), :not() and :has() use only the most specific argument. :where() is zero. :nth-child() and :nth-last-child() are one pseudo-class, plus the most specific selector after of. :host() and :host-context() add one pseudo-class plus the argument. ::slotted() adds one pseudo-element plus the argument. ::part() is one pseudo-element. A comma list returns every selector; the top numbers are the most specific, the first on a tie. against compares those numbers. At most 50 selectors in a list. Backslashes and namespaces are rejected. A bad selector is an error, not dropped. Price: $0.001 USDC per successful call (x402, Solana).
