Feature Description

Tools are utilities designed to be called by a model: their inputs are designed to be generated by models, and their outputs are designed to be passed back to models.

This feature request is to add Tools as an additional PAIG entity to perform access control on. This will enable AI agent applications integrated with PAIG to enable access control to APIs, external DBs, Internet Search functions, etc.

A proposed approach to implementing such control is via BaseTool, using the metadata field when calling the tool to pass on the username from the user running the agent application, and overload the BaseTool class to incorporate the access control based on PAIG defined policies.
