MCP lets your agent call tools hosted by external providers. The protocol handles schema discovery and execution. It does not handle behavioral history, third-party certification, or what you do when the tool at the other end is itself an autonomous agent.
Many agent teams worry about prompt injection in user messages and forget the more operationally dangerous version: untrusted tool outputs quietly steering the next decision. If the agent trusts tool output too easily, you need validation and authority separation now.
As agents use more tools through MCP and similar protocols, the danger shifts from model output alone to the trustworthiness of the capabilities they consume. If the tool is wrong, the agent can be wrong in a very expensive way.
A practical guide to MCP security and trust controls so tool-rich agent systems can stay observable, governable, and less fragile.
