description: LangDB is an AI gateway and governance platform that routes requests
  across 250+ models from providers such as OpenAI, Anthropic, Google, Meta, Mistral,
  and DeepSeek through a single project-scoped, OpenAI-compatible REST API. It layers
  routing, guardrails, tracing, cost control, and an MCP (Model Context Protocol)
  gateway on top of that unified interface.
