How the Anthropic MCP Works [At a High Level] | ClickUp

"Anthropic's Model Context Protocol (MCP) is an open, vendor-neutral standard designed to let large-language models access external data and tools through a unified client-server interface. The protocol describes primitives for tools, resources and prompts, and uses JSON-RPC over streamable HTTP or stdio to exchange requests and responses. It offers versioned specifications, multiple language SDKs, and aims to replace brittle custom integrations."

"The explosion of AI tools created a patchwork of proprietary plugins and agents that handle context and side-effects differently. Anthropic's MCP standardizes the way LLMs interact with external data sources by introducing a clear protocol with defined capabilities. This reduces duplication and helps developers build once and integrate anywhere. Early adopters like Block and Apollo integrate MCP into their workflows, and the open-source specification has been released with SDKs in multiple languages."

Anthropic's Model Context Protocol (MCP) standardizes how large language models access external data, tools, and prompts through a unified client-server interface. The protocol defines primitives for tools, resources, and prompts and transports messages via JSON-RPC over streamable HTTP or stdio. MCP provides versioned specifications, multiple language SDKs, and supports both local (stdio) and remote (HTTP) deployments, enabling personal desktop and enterprise-scale configurations. MCP reduces the need for bespoke point-to-point connectors by encouraging reusable, interoperable tools and a plug-in ecosystem. Early adopters and open-source SDKs promote broader compatibility and lower maintenance overhead across enterprise workflows.
