Model Context Protocol SDK

The Model Context Protocol (MCP) SDK provides a standardized interface for connecting large language models to external data sources and tools.

The MCP SDK enables developers to build secure, interoperable integrations between AI models and local or remote resources. By implementing a universal protocol, the SDK allows a single server to expose tools, prompts, and data to any compatible client (like Claude Desktop or IDE extensions) without custom glue code. It supports multiple languages including TypeScript, Python, and Java, utilizing transports like stdio and Streamable HTTP to maintain high-performance communication. This architecture eliminates the need for redundant API integrations, allowing models to interact with everything from local SQLite databases to complex SaaS platforms through a unified schema.
