McpAddOptions.parse constructor

McpAddOptions.parse(String rawArgs)

Parse from a raw argument string. Expected format mirrors the CLI: /mcp add [--scope <scope>] [--transport <t>] [-e KEY=val] [-H "Header: val"] [--client-id <id>] [--client-secret] [--callback-port <port>] [--xaa] <name> <command> [args...]
