Lists all design tokens (colors, spacing, radii, shadows, type, motion) from the Grocers design system.
AI agents call list_tokens to retrieve information from Grocers Design without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns design system tokens (colors, spacing, radii, shadows, type, motion) without creating, modifying, deleting, or executing any operations. It is a straightforward read-only information retrieval tool. The blast radius of misuse is minimal—an agent cannot cause harm by listing design tokens.
From the tool's definition Tool name 'list_tokens' and description 'Lists all design tokens' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Lists all design tokens (colors, spacing, radii, shadows, type, motion) from the Grocers design system. It is categorised as a Read tool in the Grocers Design MCP Server, which means it retrieves data without modifying state.
Register the Grocers Design MCP server in PolicyLayer and add a rule for list_tokens: 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 Grocers Design. Nothing to install.
list_tokens 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 list_tokens 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 list_tokens. 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.
list_tokens is provided by the Grocers Design MCP server (rogerio-ignacio-filho/grocers-design-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
