Provides a comprehensive list of all available UI components in the Mesh Design System
AI agents call list_components to retrieve information from Mesh 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 queries and returns data about available UI components without modifying, executing, or deleting anything. It is a straightforward read operation that retrieves information from the design system catalogue. The low severity reflects the minimal risk: exposing a list of available components poses no security threat to data, systems, or operations.
From the tool's definition Tool name 'list_components' and description 'Provides a comprehensive list of all available UI components' indicates a retrieval operation with no side effects.
Attacks that exploit this kind of access
Provides a comprehensive list of all available UI components in the Mesh Design System. It is categorised as a Read tool in the Mesh Design System MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mesh Design System MCP Server MCP server in PolicyLayer and add a rule for list_components: 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 Mesh Design System MCP Server. Nothing to install.
list_components 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_components 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_components. 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_components is provided by the Mesh Design System MCP Server MCP server (lukeylias/meshmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_components is one line of Mesh Design System MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
