Pass MCP config and allowed tools through claude_args to ensure tools like mcp__github_comment__update_claude_comment are properly available to Claude CLI. Key changes: - Tag mode outputs claude_args with MCP config (as JSON string) and allowed tools - Fixed shell escaping vulnerability when JSON contains single quotes - Agent mode passes through user-provided claude_args unchanged - Re-added mcp_config input for users to provide custom MCP servers - Cleaned up misleading comments and unused file operations - Clarified test workflow is for fork testing Security fix: Properly escape single quotes in MCP config JSON to prevent shell injection vulnerabilities.
