Check design tokens for accessibility compliance issues (contrast, text sizes, etc.).
AI agents call check_accessibility to retrieve information from Figma MCP Server by Bao To without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though check_accessibility 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.
Documented attack patterns abuse exactly the kind of access check_accessibility gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Figma MCP Server by Bao To, and nothing reaches the server without passing your rules. This is the rule we recommend for check_accessibility:
{
"version": "1",
"default": "deny",
"tools": {
"check_accessibility": {}
}
}check_accessibility is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
