python-sdk

LiteLLM works as either a Python SDK or a self-hosted AI gateway, exposing more than 100 providers through a unified OpenAI-compatible interface. Teams can switch among services such as OpenAI, Anthropic, Gemini, Bedrock, and Azure without rewriting every integration, while centralizing virtual keys, spend tracking, load balancing, logging, and guardrails at the gateway.

AI SDK lets TypeScript developers call multiple model providers through a consistent API for text, structured output, agents, and generative interfaces. It works with frameworks such as Next.js, React, Svelte, and Vue, either through Vercel AI Gateway or direct provider packages. Local development requires Node.js 22 or newer.

The MCP TypeScript SDK supplies separate server and client packages for implementing tools, resources, prompts, transports, and OAuth across Node.js, Bun, and Deno. Optional thin adapters connect MCP to runtimes such as Express and Hono. The main branch documents the v2 beta, while v1.x remains the supported production release.

lacuna-toolkit exposes the Lacuna Music API through a TypeScript SDK, a command-line tool, an MCP server, and an Agent Skill. Developers can generate music from Node 18+, shell scripts, an MCP-compatible client, or an AI coding agent, while the SDK also handles webhook verification. Using any surface still requires access to the Lacuna service and its credentials.
