I need you to click buttons on the test panel in the following sequence: "$BUTTON_SEQUENCE"
1. The buttons have hexadecimal labels 0-9 and A-F, with text labels like "Button 0", "Button A", etc.
2. Click each button in the sequence exactly once, in the order provided.
3. Be precise - only click the buttons in the specified sequence.
4. After completing the sequence, respond with this EXACT confirmation message:
"MCPTEST_DONE: Clicked button sequence $BUTTON_SEQUENCE"
Each button has a counter underneath showing how many times it's been clicked.
This test verifies MCPControl's ability to precisely automate UI interactions.

## Executive overview
Server-Sent Events (SSE) let the server stream a unidirectional, text-based event feed over plain HTTP. Compared with raw “streaming-HTTP” hacks or a full WebSocket upgrade, SSE provides automatic reconnection, built-in last-event IDs, and works through most corporate proxies—all while piggy-backing on the existing MCP REST port.➀ The upgrade path below adds a lightweight `SseTransport` alongside your existing HTTP and (paused) WebSocket modules, keeping the public MCP API unchanged for callers that still prefer request/response semantics. This document walks through the spec, code additions, and testing so an offline agent can implement the feature end-to-end.
---
## 1 Why SSE for MCPControl?
* **Standards-based.** Defined in the HTML Standard as the `text/event-stream` MIME type and the `EventSource` API, so every browser—and many Node polyfills—“just work”.➁ ➂
* **Cheaper than WebSockets.** No HTTP upgrade handshake (+1 RTT) and no full-duplex buffering; the server can flush whenever data is ready.➆ ➉
* **Auto-reconnect & backfill.** Clients resend `Last-Event-ID`; server can replay missed messages.➃
* **Fits MCP’s mostly-server-to-client traffic.** Tool-invocation responses, progress updates, and logs stream *out*; inbound commands remain normal POSTs.
---
## 2 High-level upgrade checklist
| Step | Owner | Key files |
|------|-------|-----------|
| 1. Add `SSE` to `TransportType` enum | `src/types/transport.ts` | |
| 2. Create `src/transports/sseTransport.ts` | new | |
| 3. Register route in `src/server.ts` (`/mcp/sse`) | server | |
| 4. Emit heartbeat & ID tracking | transport | |
| 5. Client polyfill docs (`eventsource` npm) | docs | |
| 6. Unit tests with Vitest | `test/sse.spec.ts` | |
| 7. Update README badges / docs | docs | |
(A diff view appears in §5.)

## 3 Protocol specification (SSE flavour)
### 3.1 Endpoint
```
GET /mcp/sse?auth=<jwt>&v=2025-04-30 HTTP/1.1
Accept: text/event-stream
```
Headers returned:
```
HTTP/1.1 200 OK
Content-Type: text/event-stream; charset=utf-8
Cache-Control: no-cache
Connection: keep-alive
```
> **Auth** – Re-use the existing bearer/JWT query param logic used by your REST calls; if OAuth tokens are in headers today, mirror that here.
### 3.2 Event grammar
```
:id:<ULID>
:event:<mcp-event-name> # optional; default "message"
:data:<JSON-encoded payload without newlines>
```
*Send exactly one JSON payload per event block.* An empty line terminates the event, per spec.➁ Events relevant to MCP:
| `event` | Payload schema | Direction |
|---------|----------------|-----------|
| `mcp.log` | `{ level, message, ts }` | → client |
| `mcp.response` | `{ requestId, data }` | → client |
| `mcp.heartbeat` | `{ ts }` | → client (every 25 s) |
| *(custom)* | free-form | – |
### 3.3 Keep-alive & reconnection
* Send a `comment` ping (`":\n\n"`) every 25 seconds (well under common 60 s proxy idle-timeout).➆
* Clients that disconnect will auto-reconnect after `retry:<ms>`; you may emit `retry: 3000` once at start to suggest 3 s back-off.➂
* On `Last-Event-ID`, replay from your in-memory ring buffer (configurable depth; 100 events default).

## 4 Mermaid diagrams
### 4.1 Connection handshake
```mermaid
sequenceDiagram
participant C as Client
participant S as MCPControl<br/>SSE Endpoint
C->>S: GET /mcp/sse (Accept: text/event-stream)
S-->>C: 200 OK + initial event stream
loop every 25 s
S-->>C: ":keep-alive\\n\\n"
end
Note over C,S: Any POST /mcp/tool remains<br/>separate HTTP request
```
### 4.2 State flow

## 5 Reference TypeScript implementation
<details>
<summary><code>src/transports/sseTransport.ts</code></summary>
```ts
import { Response } from 'express';
import { ULID } from 'ulid';
import { Transport } from './baseTransport';
export class SseTransport extends Transport {
private clients = new Set<Response>();
private replayBuffer: { id: string; data: string }[] = [];
attach(app: import('express').Express) {
app.get('/mcp/sse', (req, res) => {
res.set({
'Content-Type': 'text/event-stream; charset=utf-8',
'Cache-Control': 'no-cache',
Connection: 'keep-alive',
});
res.flushHeaders(); // send headers right away
this.clients.add(res);
// replay missed events if Last-Event-ID is present
const lastId = req.header('Last-Event-ID');
if (lastId) {
this.replayBuffer
.filter(e => e.id > lastId)
.forEach(e => res.write(e.data));
}
req.on('close', () => this.clients.delete(res));
});
// ping loop
setInterval(() => this.broadcast(':\n\n'), 25_000);
}
/** Broadcasts a JSON payload under the given event name */
emitEvent(evt: string, payload: unknown) {
const id = ULID();
const data =
`id:${id}\n` +
(evt ? `event:${evt}\n` : '') +
`data:${JSON.stringify(payload)}\n\n`;
this.replayBuffer.push({ id, data });
if (this.replayBuffer.length > 100) this.replayBuffer.shift();
this.broadcast(data);
}
private broadcast(chunk: string) {
for (const res of this.clients) res.write(chunk);
}
}
```
</details>
### 5.1 Server hook (`src/server.ts` delta)
```diff
import { HttpTransport } from './transports/httpTransport';
+import { SseTransport } from './transports/sseTransport';
const app = express();
const httpTransport = new HttpTransport(app);
+const sseTransport = new SseTransport(app);
```
Everywhere you currently call `transport.emit(...)`, inject the SSE transport as well.
---
## 6 Offline client examples
### 6.1 Browser / WebView
```js
const es = new EventSource('/mcp/sse?auth=' + jwt);
es.onopen = () => console.log('open');
es.onmessage = (e) => console.log(JSON.parse(e.data));
es.addEventListener('mcp.response', ({ data }) => {
const { requestId, data: body } = JSON.parse(data);
});
```
### 6.2 Node 18+ (CommonJS) – no native `EventSource`
```bash
npm i eventsource # vendored in repo for offline use
```
```js
const EventSource = require('eventsource');
const es = new EventSource('http://localhost:3232/mcp/sse?auth=' + token);
```
(Offline agents should symlink `node_modules/eventsource` or embed a minimal polyfill; the official package is 600 lines, no deps.)➂
---
## 7 Testing recipes
| Tool | Command | Expect |
|------|---------|--------|
| `curl` | `curl -N http://localhost:3232/mcp/sse` | continuous stream with `data:` lines |
| Browser dev-tools | `new EventSource('/mcp/sse')` | `readyState === 1` |
| Vitest | mock Response objects; assert write calls | heartbeat every 25 s |
---
## 8 Security considerations
1. **CORS** – mirror REST settings; disallow “*” in prod.
2. **Bearer token leakage** – prefer `Authorization: Bearer` header; avoid query if referrers might log.
3. **Denial-of-service** – cap open connections (`MAX_SSE_CLIENTS=100` env); shed oldest if exceeded.
4. **Sensitive clipboard/mouse data** – enforce existing MCP permission model before emitting events.
