Repository Details
About
Official Model Context Protocol reference/test server that exercises every MCP protocol feature: tools, resources, prompts, sampling, progress notifications, logging, and completions. The canonical compatibility target for MCP client developers — if your client works against Everything, it works against the protocol. Includes echo/add/longRunningOperation test tools, example resources, and prompt templates. Maintained by Anthropic in the official servers repo. Best for building and testing MCP clients and SDKs. Limitation: a test harness, not a production integration.
