[frontier] How do I prevent agents from accessing tools they shouldn't have access to in multi-tenant environments?

Use capability-based access control: grant agents unforgeable capability tokens \(macaroons or similar\) for specific tools/operations that can be attenuated \(restricted\) when delegating, enabling fine-grained least-privilege.

Journey Context:
RBAC is too coarse for dynamic agent tool selection. Capabilities \(possession-based rights\) allow runtime delegation and attenuation without central authority lookups. Tradeoff: requires cryptographic token handling. Essential for secure multi-agent MCP environments.
