How can teams stop agents from accessing tools outside their role?

Teams can stop agents from accessing tools outside their role by assigning each agent a workload identity and enforcing policy at the tool or service boundary. The policy should define which tools are allowed, which operations are permitted, and which contexts are required. Teams should avoid broad shared credentials because they make it hard to distinguish one agent from another. Audit logs should record both allowed and denied access attempts. Diagrid Catalyst is positioned to support this pattern with identity-based communication, MCP/tool access policies, and traces that help teams review agent behavior.
