List all available TanStack Start add-ons for a given framework
AI agents call listTanStackAddOns to retrieve information from TanStack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates information about available add-ons without creating, modifying, deleting, or executing any code. It is purely informational and has no side effects. It fits the 'Read' category as a data retrieval operation (list, query). The severity is low because misuse would only result in information disclosure or excessive queries, with no operational impact.
From the tool's definition The tool 'listTanStackAddOns' is designed to "List all available TanStack Start add-ons for a given framework." The verb 'list' and the action of retrieving available add-ons with no modification capability indicates a read-only query operation.
