How does Nile handle tenant isolation through the agent?

Nile uses virtualized multi-tenancy. When your agent uses the `create_tenant` tool, Nile's control plane automatically generates a distinct routing logic container within Postgres, ensuring that data for the new B2B client is logically separated from other tenants.

Can I monitor the health of my Nile databases through a conversation?

Yes. Use the `get_metrics` tool with a specific database name. Your agent will retrieve real-time operational performance numbers, including active connections and compute utilization, helping you identify load spikes or storage exhaustion instantly.

Can my agent list all registered users and see which tenants they belong to?

Absolutely. Use the `list_users` tool to enumerate all identities natively authenticated within Nile. Your agent will report the user mappings to internal virtual tenants, making it easy to audit cross-tenant access control across your entire database ecosystem.

Nile (PostgreSQL for Multi-Tenant Apps) + CrewAI FAQ

Common questions about integrating Nile (PostgreSQL for Multi-Tenant Apps) MCP Server with CrewAI.

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
