# Gateway and Stream

> Expose and route LIOP traffic with hybrid and stream bridges

The SDK includes transport components for routing MCP traffic across local and mesh environments.

## LiopHybridGateway

`LiopHybridGateway` multiplexes HTTP/1.1 and HTTP/2 (gRPC) over a single TCP port and delegates MCP requests through `LiopMcpRouter`.

```typescript theme={null}
import { LiopHybridGateway, LiopServer } from "@nekzus/liop";

const server = new LiopServer({ name: "gateway-node", version: "1.0.0" });
const gateway = new LiopHybridGateway(server, null, 50051);

await gateway.listen(3000);
// ... serve traffic
await gateway.stop();
```

## LiopMcpRouter

`LiopMcpRouter` is the request dispatcher used by the gateway and the CLI agent. It handles:

* MCP method dispatch (`tools/list`, `tools/call`, `resources/*`, `prompts/*`)
* Local tool execution and remote provider resolution via mesh manifests
* ZK verification for remote responses
* Manifest caching and adaptive discovery behavior

## LiopStreamBridge

`LiopStreamBridge` exposes a `LiopServer` over Streamable HTTP transport with session isolation.

```typescript theme={null}
import { LiopServer, LiopStreamBridge } from "@nekzus/liop";

const server = new LiopServer({ name: "stream-node", version: "1.0.0" });
const stream = new LiopStreamBridge(server, {
  port: 3000,
  maxSessionsPerIp: 10,
  sessionTimeoutMs: 30 * 60 * 1000
});

await stream.start();
// ... streamable MCP traffic on /mcp
await stream.stop();
```

## Security Notes

* `LiopStreamBridge` supports Zero-Trust bearer enforcement via `ZERO_TRUST_TOKEN`.
* Sessions are isolated and evicted when idle to reduce long-lived attack surfaces.
* Gateway/router components preserve MCP JSON-RPC compatibility while keeping mesh-native routing behavior.
