MCP Apps SDK

The Model Context Protocol (MCP) SDK provides the standardized framework for building secure, interoperable tools that connect LLMs to local and remote data sources.

The MCP Apps SDK (specifically the TypeScript and Python implementations) enables developers to build servers that expose data and tools to AI agents like Claude Desktop. By implementing a standardized JSON-RPC 2.0 transport layer, the SDK handles the heavy lifting of resource discovery, tool execution, and prompt management. It allows developers to turn any API or database (such as PostgreSQL, Google Drive, or Slack) into a structured context provider that LLMs can query safely. This architecture eliminates the need for custom integrations for every new AI model, providing a single protocol for universal tool interoperability.
