# MCP SSE Polling Demo Server
|
|
|
|
Demonstrates the SSE polling pattern with server-initiated stream close for long-running tasks (SEP-1699).
|
|
|
|
## Features
|
|
|
|
- Priming events (automatic with EventStore)
|
|
- Server-initiated stream close via `close_sse_stream()` callback
|
|
- Client auto-reconnect with Last-Event-ID
|
|
- Progress notifications during long-running tasks
|
|
- Configurable retry interval
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
# Start server on default port
|
|
uv run mcp-sse-polling-demo --port 3000
|
|
|
|
# Custom retry interval (milliseconds)
|
|
uv run mcp-sse-polling-demo --port 3000 --retry-interval 100
|
|
```
|
|
|
|
## Tool: process_batch
|
|
|
|
Processes items with periodic checkpoints that trigger SSE stream closes:
|
|
|
|
- `items`: Number of items to process (1-100, default: 10)
|
|
- `checkpoint_every`: Close stream after this many items (1-20, default: 3)
|
|
|
|
## Client
|
|
|
|
Use the companion `mcp-sse-polling-client` to test:
|
|
|
|
```bash
|
|
uv run mcp-sse-polling-client --url http://localhost:3000/mcp
|
|
```
