Provides a full list of Shadcn Space components. Agents can use this to discover components to build pages or sections within a project.
AI agents call listComponents to retrieve information from Shadcn Space MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists available UI components for informational purposes only. It enables discovery of component options but does not modify, execute, delete, or create any data or resources. The capability is purely read-only with no destructive, financial, or code execution implications. Low severity due to the harmless nature of accessing a component catalog.
From the tool's definition Tool name 'listComponents' and description 'Provides a full list of Shadcn Space components' indicate a query/discovery operation with no side effects.
Attacks that exploit this kind of access
Provides a full list of Shadcn Space components. Agents can use this to discover components to build pages or sections within a project. It is categorised as a Read tool in the Shadcn Space MCP MCP Server, which means it retrieves data without modifying state.
Register the Shadcn Space MCP server in PolicyLayer and add a rule for listComponents: 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 Shadcn Space MCP. Nothing to install.
listComponents 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 listComponents 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 listComponents. 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.
listComponents is provided by the Shadcn Space MCP server (shadcnspace/shadcnspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
