Lints a CSS, JSX, TSX, or HTML snippet against Grocers brand invariants and tokens.
AI agents call validate_snippet 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.
The tool performs validation/linting of code snippets against design system rules. Linting is inherently a read-only operation—it inspects input, performs analysis, and returns feedback without modifying data, executing arbitrary code, or triggering external operations. The tool name 'validate_snippet' and description confirm this is a static analysis tool with no side effects.
From the tool's definition Tool description: 'Lints a CSS, JSX, TSX, or HTML snippet against Grocers brand invariants and tokens.' Linting is a static analysis operation that validates code without modifying it, executing it, or creating side effects.
Attacks that exploit this kind of access
Lints a CSS, JSX, TSX, or HTML snippet against Grocers brand invariants and tokens. 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 validate_snippet: 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.
validate_snippet 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 validate_snippet 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 validate_snippet. 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.
validate_snippet 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.
