Developers building MCP servers must be aware that different clients like Claude Desktop, Cursor, and Visual Studio Code support varying subsets of the protocol's features. While core functionalities like tool use and calling are universally supported, features such as resources, prompts, and sampling are client-specific, with sampling being exclusive to Claude Desktop. MCP Workbench offers a testing solution to verify server compatibility across these diverse clients. AI
