Description

Components for building MCP servers and clients that enhance LLM reasoning with custom data, code, and context.

The Model Context Protocol (MCP) standardizes how large language models interact with external systems, making it possible to expose custom data, functionality, and predefined instructions in a way models can use programmatically. MCP gives you a structured way to connect LLMs to your organization's data, tools, and workflows, making their output more relevant to your specific needs.

MCP SDK is a development library that streamlines implementation of MCP servers and clients. Our components use an intuitive event-driven API that enables LLMs to retrieve relevant data, trigger custom operations, follow reusable instructions, and more. Whether you're building AI agents or integrating LLMs into backend systems, MCP SDK acts as the connective layer between language models and your application logic. MCP SDK supports all major protocol features like tools, sampling, prompts, and resources.

Bi-Directional Communication

MCP SDK enables seamless, two-way communication between your systems and LLMs. MCP servers built with MCP SDK can expose custom functionality, resources, and prompts that LLMs can call in real time. Clients built with MCP SDK act as the bridge between LLMs and those server-side capabilities by initiating requests and retrieving data, functionality, and instructions that reflect your organization’s unique context.

Easy Setup

MCP SDK ensures that interfacing with LLMs is as easy as possible. With just a few basic configuration settings, MCP hosts can launch your MCP server quietly in the background to facilitate communication. Whether you want to communicate over standard input and output or HTTP, MCP SDK minimizes the overhead required to integrate with all standard MCP hosts.
