HyperChat — MCP Client

How to use HyperChat?

Configure your API key (any OpenAI‑compatible LLM service), then ensure you have uv (or uvx) and nodejs (with npx) installed. Run npx -y @dadigua/hyper-chat to start a local web server on port 16100 with default password 123456. Alternatively, pull the Docker image with docker pull dadigua/hyperchat-mini:latest.
