MegaGrindStone/mcp-web-ui
MCP Web UI is a browser-based host in the Model Context Protocol architecture, written in Go. It provides a chat interface to large language models while handling the context aggregation and the coordination between the model and the MCP servers that supply tools. Four providers are supported behind one interface: Anthropic Claude models, OpenAI GPT models, Ollama for locally served models, and OpenRouter for access to many providers at once. Responses stream to the browser over Server-Sent Events, and conversations are persisted in an embedded BoltDB store, so chat history survives restarts. Everything is driven by a YAML configuration file placed in the user config directory. It sets the listening port, log level and log format, the default system prompt and the prompt used to generate chat titles, and a full LLM block with the provider, model name and generation parameters such as temperature, topP, topK, frequency and presence penalties, maximum tokens and stop sequences. Provider-specific settings cover the Ollama host URL, the Anthropic and OpenAI and OpenRouter API keys, which can also come from environment variables, and a custom OpenAI-compatible endpoint. A separate genTitleLLM block allows a cheaper model to generate conversation titles, falling back to the main model if omitted. MCP servers are declared in two sections: mcpSSEServers, each with a URL and a maximum payload size, and mcpStdIOServers, each with a command and its arguments, with worked examples for the official filesystem server run through npx and for a go-mcp filesystem server. The application needs Go 1.23 or newer and can be run directly with go run or built into a Docker image that mounts the config file and reads API keys from the environment.
