MCP has become an important part of the agent security conversation, and for good reason. It gives teams a clean way to connect agents to tools, govern which tools they can call and bring more consistency to how those interactions are managed.
But the MCP layer sits in the middle of a much longer action chain. A user or another agent starts the task, the agent decides what it needs to do, MCP handles the tool interaction and then that tool acts inside a downstream system using whatever permissions are available there.
That distinction matters because controlling the tool call is not always the same as controlling the final action.
In this 30-minute technical explainer, P0 Security Co-founders Shashwat Sehgal and Greg Danyi will map MCP into the full agentic action chain and show where its control point begins and ends.
They’ll talk about the difference between tool access and target-system authorization, why provenance can get lost as requests move through agents and service accounts and where standing credentials can still leave agents with more access than the task requires.
This session is for security, identity, platform and AI teams that are already connecting agents to enterprise systems or deciding how they will.
If you are evaluating MCP gateways, designing your agent security stack or trying to understand whether your current controls cover the full execution path, this will give you a practical way to think about the problem.
