Get a list of all available shadcn/ui components
AI agents call list_shadcn_components to retrieve information from shadcn-ui MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval operation that queries component metadata. It has no side effects, cannot modify or delete data, and does not execute code or trigger external operations. The verb 'list' and action 'get a list' are characteristic of Read category tools. Misuse by an AI agent (e.g., repeated calls) carries negligible risk.
From the tool's definition The tool 'list_shadcn_components' retrieves and lists available UI components with no indication of modification, deletion, or execution. The description states it 'Get[s] a list of all available shadcn/ui components' — a pure retrieval operation.
