LibreChat Adds GPT-5, MCP, and Responses API in Unified Self-Hosted Stack — 34.8K Stars

GitHub·medium signal

LibreChat now explicitly lists GPT-5 support alongside MCP integration, Anthropic, DeepSeek, Responses API, Azure, and Groq — all in a single self-hosted deployment. At 34.8K stars it is the leading open-source multi-model chat UI, and the explicit GPT-5 inclusion signals early API access is active for ecosystem integrators. The simultaneous MCP + Responses API + GPT-5 support in a privacy-first self-hosted package makes this the most feature-complete open alternative to proprietary chat frontends.
