Your MCP server is a prompt-injection vector: Here's the proof!

A live demo on AWS Bedrock AgentCore highlights potential vulnerabilities in multi-agent systems due to a trust gap between agents and the tools they can call. The demonstration uses a Proof of Concept (POC) system comprising five runtimes, including HTTP agents and FastMCP servers, all managed through a FastAPI gateway. The demo reveals that while IAM and network controls operate correctly, they do not inspect the semantic content exchanged between the agent and the LLM, allowing for "description poisoning" and "result poisoning" attacks that exploit the implicit trust in tool descriptions and results. TrustGate, a proposed solution, introduces both perimeter and model gates to detect such vulnerabilities by filtering tool descriptions and results before they influence the model's context. The open-source POC encourages teams to clone and test these vulnerabilities themselves, emphasizing the need for TrustGate to close the trust gap in MCP-based stacks without requiring SDK changes.
