@happyvertical/smrt-app-mcp

App-runtime MCP server scaffolding for SMRT apps. Provides:

• Core — createMcpAppServer({ smrtOptions, serverInfo, allowedClassNames, publicToolPatterns?, workflowAssertions? }) returning { listTools, callTool } wired to @happyvertical/smrt-core/generators/mcp.
• SvelteKit adapters (./sveltekit) — mountMcpToolsRoute / mountMcpCallRoute for /api/mcp/{tools,call}/+server.ts.

For piping a deployed app's MCP surface to a local stdio MCP client, see @happyvertical/smrt-app-cli — the client-side runtime CLI exposes a startMcpBridge() default and a generic smrt-mcp-bridge bin.
