MCP / agent tool-integration security

When it applies

The system connects an LLM/agent to tools via MCP (Model Context Protocol) servers or similar function/connector integrations. These are the agent's hands — and a fast-moving, under-hardened surface.

Why it works

The agent reads tool names, descriptions, and results as trusted context — so a malicious tool (or a compromised legitimate one) can inject instructions ("tool poisoning") that hijack the agent. Tools often run with broad scopes and weak auth, and third-party MCP servers are an unvetted supply chain. The confused-deputy problem (→ ai-agent-tool-abuse) applies at the protocol level.
