# Native Zig Performance and Protocol Integrations

> Migrating to OpenTUI's native Zig core via FFI and implementing dynamic Model Context Protocol stdio clients.

Terminal layouts must be fast and flicker-free. Traditional JS-heavy rendering engines can suffer from layout tearing or line duplication when printing continuous streams. This release transitions Hypr's layout layers to a native Zig core.

## Native OpenTUI Core

By shifting from React Ink to **OpenTUI**, all layout math occurs inside native Zig binaries bridged using Bun FFI. It locks rendering bounds to a strict screen-sized matrix, rendering borderless layouts with zinc backgrounds. Alternate screen buffers switch automatically on boot, exiting cleanly back to the host shell.

## Subprocess Stream Ring-Buffer

To prevent external compiler streams from polluting TTY frames, all shell outputs are directed into a memory-resident `LogRingBuffer`. It isolates the stream feeds from the main rendering loop, retaining the last 200 lines of logs.

## Model Context Protocol (MCP) Client

Hypr is now pluggable. Using JSON-RPC 2.0 stdio protocols, users can connect local or remote MCP servers:

```bash theme={null}
connect_mcp_server node ./brave-search-server.js
```

The client queries tool definitions, maps them to dynamic Zod configurations, and exposes the injected tools directly to the model.
