What redis_tenant_ops does on RedisNexus

AI agents use redis_tenant_ops to create or update resources in RedisNexus — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your RedisNexus environment.

WHY IT NEEDS A POLICY

Why redis_tenant_ops needs a policy

The tool name 'redis_tenant_ops' combined with 'manages per-tenant' implies it can perform create/update/delete operations on Redis data across multiple tenants. The multi-tenant scope significantly raises the blast radius since misuse could affect multiple customers. The description is truncated, reducing confidence.

From the tool's definition 'Multi-tenant Redis operations for SaaS platforms. Manages per-tenant' — description is incomplete/truncated, but 'operations' and 'manages' suggest read/write capabilities across multiple tenants
