MCP Web UI

What is MCP Web UI?

MCP Web UI is a web-based user interface that serves as a Host within the Model Context Protocol (MCP) architecture. It provides a powerful and user-friendly interface for interacting with Large Language Models (LLMs) while managing context aggregation and coordination between clients and servers. It runs on Go 1.23+ and can be deployed locally or via Docker.

How to use MCP Web UI?

Clone the repository, copy config.example.yaml to ~/.config/mcpwebui/config.yaml, and set API keys as environment variables (ANTHROPIC_API_KEY, OPENAI_API_KEY, OPENROUTER_API_KEY). Run the application with go run ./cmd/server/main.go or use Docker with docker build -t mcp-web-ui . followed by docker run -p 8080:8080. The server listens on port 8080 by default and is configured via config.yaml.
