Build AI chat interfaces with custom backends, authentication, and context injection. Use when integrating chat UI with AI agents, adding auth to chat, injecting user/page context, or implementing httpOnly cookie proxies. Covers ChatKitServer, useChatKit, and MCP auth patterns. NOT when building simple chatbots without persistence or custom agent integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building Chat Interfaces
Build production-grade AI chat interfaces with custom backend integration.
## Quick Start
```bash
# Backend (Python)
uv add chatkit-sdk agents httpx
# Frontend (React)
npm install @openai/chatkit-react
```

## Core Architecture

## Backend Patterns
### 1. ChatKit Server with Custom Agent
```python
from chatkit.server import ChatKitServer
from chatkit.agents import stream_agent_response
from agents import Agent, Runner
class CustomChatKitServer(ChatKitServer[RequestContext]):
"""Extend ChatKit server with custom agent."""
async def respond(
self,
thread: ThreadMetadata,
input_user_message: UserMessageItem | None,
context: RequestContext,
) -> AsyncIterator[ThreadStreamEvent]:
if not input_user_message:

How to install
mdr add mjunaidca/mjs-agent-skills/building-chat-interfaces@sha256:8d763134836205ecThe line at the top of this page pins the label git:20251222.3cc0c3c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
