everything

The Everything MCP Server is designed to demonstrate the full capabilities of the MCP protocol. It is not intended for production use but serves as a comprehensive testbed for MCP client developers. This server implements various MCP features, including prompts, tools, resources, sampling, and different transport mechanisms to provide a complete overview of the protocol.

It provides several ways to run the server, including via NPX, Docker, and from source, supporting different transport layers like stdio, HTTP+SSE (deprecated), and Streamable HTTP. This allows developers to test their MCP clients against a wide range of configurations and scenarios.

The server's features are documented in the Server Features document, which provides a detailed list of registered MCP primitives and protocol features.
