Simon Willison documents the process of connecting custom Model Context Protocol (MCP) servers to Claude and ChatGPT web interfaces, noting that while possible, setup is non-trivial. The guide addresses a practical need for developers seeking to extend these AI platforms with external data sources or tools via MCP.
Background
