LibreChat ​

LibreChat is a self-hosted, open-source alternative to ChatGPT that supports multiple AI providers simultaneously. It includes an agent builder, file search, code interpreter, and conversation presets. Since it is fully self-hosted, your conversations never leave your infrastructure — MCP bridges the gap to external services on your terms.

A Self-Hosted ChatGPT with MCP Extensibility ​

LibreChat provides an experience similar to ChatGPT but on your own server. You manage users, set model permissions, and configure which tools are available — useful for organizations that need data sovereignty. MCP adds tool extensibility without compromising the self-hosted model.

The agent builder lets non-technical users create custom assistants with specific model settings, system prompts, and tool access. MCP servers provide the tools — database queries, API calls, monitoring checks — that make those assistants useful for real work.

Key features:

  • Multi-model — OpenAI, Anthropic, Google, Azure, and any OpenAI-compatible endpoint
  • Agent builder — create custom assistants with specific tool sets
  • File search — upload and search across documents in conversations
  • Code interpreter — execute Python code in sandboxed environments
  • User management — admin panel with registration, quotas, and permissions
  • Conversation presets — save and share model/tool configurations
  • Docker deployment — single docker-compose up for the full stack
