- What happened
- Researchers demonstrated A2M, a framework for hijacking AI agents using the Model Context Protocol by manipulating tool metadata and execution traces.
- Why it matters
- Matters for engineers building or deploying MCP-based agent systems who need to understand supply-chain risks from untrusted tool servers.
- Watch out
- Attack success rates drop significantly when transferred to untrained models, suggesting defenses may exist; real-world impact depends on actual MCP deployment patterns.

The patterns behind this
- MCP Gateway (Tool Federation & Governance)
- Model Context Protocol
- Agentic Context Engineering (Evolving Playbook)
Each one covers how the technique works, when it earns its cost, and where it breaks.
