MCP for agent-to-agent comms may be the riskiest protocol you've never heard of

Trust gaps in the new protocol spread malicious prompts from one agent to another.
The short version
- The adoption of AI agents in millions of organizations is creating new opportunities for attackers to make them take malicious actions, such as exfiltrating database contents and sensitive business and personal information.
- Independent researcher Syed Anas Mohiuddin tested agents from organizations including Google, JP Morgan Chase, Weviate, Rapid7, the French government’s interministerial digital directorate, and the US federal government.
- His proof-of-concept attacks exploit trust gaps in MCP, short for Model Context Protocol .

The standard is one way AI apps and agents communicate with each other inside an internal network. The illustration below shows a simplified MCP in action.
Why it matters
Many special-purpose agents lack the guardrails that might normally mitigate the most harmful consequences of a prompt injection.
