Get all available design token categories
AI agents call get-design-token-categories to retrieve information from Visa Design System MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about design token categories from Visa's design system. It has no side effects, cannot modify data, execute code, or trigger external operations. It is purely informational access to design system resources, consistent with other 'get-' and 'search-' tools on the server that are all read operations.
From the tool's definition Tool name 'get-design-token-categories' and description 'Get all available design token categories' indicate a retrieval operation with no modification or execution of code/commands.
