This MCP server, developed by Anthropic, serves as a comprehensive demo suite for MCP client implementations. It exercises the full range of MCP protocol features including prompts, tools, resources, and sampling. Built in TypeScript, the server implements various tools like echo, math operations, and LLM sampling, as well as 100 test resources in both plaintext and binary formats. By providing a standardized testing ground, this server enables MCP client developers to validate their implementations against a wide array of protocol functionalities. It is particularly useful for ensuring compatibility, debugging edge cases, and demonstrating the capabilities of the MCP protocol in a controlled environment.
