MCP SDK adds HTTP and HTTPS transport support allowing MCP servers to connect LLM clients across distributed environments.
MCP SDK (included in Red Carpet Subscription) is a developer-focused library that reduces the complexity of implementing MCP (Model-Context-Protocol) servers and clients. Built around an event-driven API, it enables large language models (LLMs) to interact with your application logic - retrieving data, invoking tools, executing predefined operations, or following structured prompts.
The latest MCP SDK release adds full support for HTTP and HTTPS transport, giving developers more options for deploying MCP servers in modern, distributed architectures. With network-based connectivity, Large Language Model (LLM) clients can securely connect to MCP servers across environments, making it easier to integrate AI capabilities into cloud-native and multi-service systems. The included MCPServer component simplifies the process of building servers that link LLMs such as Claude to custom data sources, internal services, and application logic, helping teams extend AI functionality into real-world processes with minimal friction.
