Policy Decision Point
A decision component in access control architectures that receives authorization queries from a PEP, evaluates whether a single tool call is permitted based on three dimensions—caller identity, tool scope, and task context—and returns a decision result.

Embedding authoritative policy into each Agent implementation easily leads to inconsistent enforcement; the alternative is to separate policy decisions from framework-specific execution, but a key requirement is that the runtime must not offer an alternative path that bypasses enforcement.
In engineering practice, the control point is usually called the Policy Enforcement Point (PEP), paired with the Policy Decision Point (PDP); the PEP sits on the link between the agent and the tools (such as a tool gateway, an MCP server proxy, or unified tool-call middleware) and is responsible for asking the PDP whether a call is allowed before each call is issued and allowing or denying it accordingly.
