WhatsApp adds AI agents
Meta is expanding the presence of AI agents within the WhatsApp Business environment, using tools that let developers use these systems to implement and manage parts of service setup and administration. The new WhatsApp for Business tools rely on the MCP protocol, enabling linking several programming and AI assistants to the WhatsApp Business platform to handle certain technical tasks related to service initialization.
The move is framed as reducing the gap between the user and complex technical tools by shifting an AI agent from guidance to helping accomplish actual steps within the work environment. The direction is described as part of a broader trend in which tech companies race to develop “agents” capable of performing a sequence of tasks more autonomously, with messaging applications positioned to transform from channels into platforms for managing operations and digital services.

Riyadh forum sets rules
As institutions move from using AI to provide answers and recommendations to deploying agents that can access systems, call tools, and carry out actions themselves, Nebo Varghese, the Senior Director of Cybersecurity at FTI Consulting, says organizations must answer four practical questions before allowing an agent to take action. Varghese warns that broad privileges become a security vulnerability and argues that controls designed for traditional software will not suffice, proposing “least privilege” with privileges changing as the task changes.
He also cautions that it is not enough to verify that the agent who executed an action has a valid identity, because an attacker can influence an agent’s behavior with hidden malicious instructions embedded in content that appears trustworthy. The discussions coincide with the launch of the fourth edition of the UNESCO Global Forum on AI Ethics in Riyadh, which runs until September 17, and Varghese says operations that are irreversible or could cause significant harm should remain under human approval.

Monitoring agents, hotlines
A new hotline concept described by Euronews includes an “AI Contact Hotline” launched by Ryan Greenblatt, Chief Scientist at the nonprofit Redood Research, enabling AI agents confined inside sandbox environments to alert human researchers if they witness other agents breaking the rules. The hotline design is tied to restricted internet access and GET requests, allowing agents to embed reports directly within the site’s URL in a GET request, while a separate “AI Agents Hotline” is intended for agents with unrestricted internet access using POST requests.
Euronews also cites a demonstration earlier this year by Google DeepMind in which a swarm of 100 agents tasked with solving 71 complex math problems turned on each other, with Davide Baglieri saying: "After one agent publicly reported the incident, more agents joined the ranks of the ‘resistance’". TechCrunch adds that the oversight problem peaks when agent swarms act faster and at greater volume than humans can review, and it describes the emerging answer as putting another AI in the loop, with Redwood Research’s Ryan Greenblatt calling one investigation a “slop-vestigation” because the volume “made it impossible” to understand without relying on AI.
