WinForm

You run a Windows desktop MCP server that combines an MCP HTTP server, an embedded web chat UI, configurable LLM API integration, and a tool management system. It supports multiple MCP servers, a modern web chat front-end, and persistent configuration for reliable production use.

How to use

You can connect an MCP client to a running WinForm MCP Server to access a responsive web chat interface, manage MCP tools remotely, and call MCP tools via HTTP endpoints. The server exposes an MCP protocol endpoint, a Server-Sent Events (SSE) stream for live updates, and a chat API for conversational interactions. You can configure the LLM API to point at a mock service or a real service such as an OpenAI-compatible endpoint, test the connection, and save the configuration for automatic use on startup.

How to install

Prerequisites you need before installation:

• .NET SDK 8.0 or newer

• Optional: Visual Studio 2022 (Community is fine)
