|---|---|---|---|
color | string | Yes | e.g. #1e90ff, rgb(30 144 255), hsl(210 100% 56%), oklch(0.65 0.18 250), tomato |
against | string | — | Optional second colour (background) for a WCAG contrast check |
Parameters from the server's own tool schema.
Why color_convert is rated Medium
An AI agent can call color_convert faster than any human can review: one bad instruction and it creates or modifies resources in ScorpTech x402 API by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs color_convert 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 color_convert, this is the rule to start with:
color_convert 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.
The button opens the PolicyLayer dashboard: create your workspace, connect ScorpTech x402 API, apply this rule, and every color_convert call is checked against it from then on.
