cli--permission-prompt-tool
Specify an MCP tool to handle permission prompts in non-interactive mode. Claude Code waits for that tool's MCP server to connect before running the first turn, up to the MCP_TIMEOUT startup timeout, 30 seconds by default. <br /><br />The prompt tool can't approve an MCP tool marked as requiring user interaction: Claude Code converts an allow result for one to a deny. This restriction requires Claude Code v2.1.199 or later
