Curious how you handle tool permissions in practice. Is it just a whitelist, or can you scope down to specific rows/fields?
The way to scope down access, would be to use an Automation (our RPA, zapier-like section). You can give an automation parameters and control exactly what it does, then use it as an agent tool.
In future, we'll be looking into user-delegate permissions. I.e. you give your users a role (RBAC) in Budibase, which gives them access to certain resources. Any agent calls will be done under the user's permissions. This is not always desirable - sometimes you want your agent to have more permissions that the user - so this will need to be configurable at some level.
