## Example index

| Scenario | Description | File |
| ----------------------------------------- | ----------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- |
| Streamable HTTP server (stateful) | Feature-rich server with tools/resources/prompts, logging, tasks, sampling, and optional OAuth. | [`src/simpleStreamableHttp.ts`](src/simpleStreamableHttp.ts) |
| Streamable HTTP server (stateless) | No session tracking; good for simple API-style servers. | [`src/simpleStatelessStreamableHttp.ts`](src/simpleStatelessStreamableHttp.ts) |
| JSON response mode (no SSE) | Streamable HTTP with JSON-only responses and limited notifications. | [`src/jsonResponseStreamableHttp.ts`](src/jsonResponseStreamableHttp.ts) |
| Server notifications over Streamable HTTP | Demonstrates server-initiated notifications via GET+SSE. | [`src/standaloneSseWithGetStreamableHttp.ts`](src/standaloneSseWithGetStreamableHttp.ts) |
| Output schema server | Demonstrates tool output validation with structured output schemas. | [`src/mcpServerOutputSchema.ts`](src/mcpServerOutputSchema.ts) |
| Form elicitation server | Collects **non-sensitive** user input via schema-driven forms. | [`src/elicitationFormExample.ts`](src/elicitationFormExample.ts) |
| URL elicitation server | Secure browser-based flows for **sensitive** input (API keys, OAuth, payments). | [`src/elicitationUrlExample.ts`](src/elicitationUrlExample.ts) |
| Sampling + tasks server | Demonstrates sampling and experimental task-based execution. | [`src/toolWithSampleServer.ts`](src/toolWithSampleServer.ts) |
| Task interactive server | Task-based execution with interactive server→client requests. | [`src/simpleTaskInteractive.ts`](src/simpleTaskInteractive.ts) |
| Hono Streamable HTTP server | Streamable HTTP server built with Hono instead of Express. | [`src/honoWebStandardStreamableHttp.ts`](src/honoWebStandardStreamableHttp.ts) |
| SSE polling demo server | Legacy SSE server intended for polling demos. | [`src/ssePollingExample.ts`](src/ssePollingExample.ts) |

| Class-based decorators (legacy) | Class methods decorated with `@McpTool`, `@McpResource`, `@McpResourceTemplate`, `@McpPrompt`. Uses legacy TypeScript decorators (`experimentalDecorators: true`). | [`src/legacyClassDecoratorsExample.ts`](src/legacyClassDecoratorsExample.ts) |
| Class-based decorators (TC39 Stage-3) | Same pattern, built on TC39 Stage-3 decorators and `Symbol.metadata` instead of prototype-attached arrays. Compiles under its own `tsconfig.standard-decorators.json` (`experimentalDecorators: false`). Run with `pnpm tsx --tsconfig=tsconfig.standard-decorators.json src/classDecoratorsExample.ts`. | [`src/classDecoratorsExample.ts`](src/classDecoratorsExample.ts) |
