Model Context Protocol (MCP)

In late 2024, Anthropic announced the Model Context Protocol (MCP), an open standard to enable LLMs to access external data sources and tools in a secure and controlled manner. Since then, several LLM providers and companies have adopted this specification, including OpenAI, Google, and Microsoft.

The project is open source and available on GitHub. It includes several SDKs and examples to help developers get started. That's why several companies and developers have started developing MCPs and sharing their implementations. Let's name some of them:
