What is the Nile (PostgreSQL for Multi-Tenant Apps) MCP Server?
Connect your Nile account to any AI agent and take full control of your tenant-aware PostgreSQL infrastructure, B2B tenant isolation, and database performance through natural conversation.
What you can do
- Database Orchestration — List high-level PostgreSQL targets and retrieve detailed configuration JSON, including storage sizes and state tracking directly from your agent
- Virtualized Multi-Tenancy — Instantly provision and manage highly isolated virtual tenant boundaries (shards) to support multi-tenant SaaS architectures automatically within Postgres
- Operational Performance — Pull exact monitoring metrics reflecting true active connections, storage exhaustion layers, and compute utilization tracked over your database instances
- User Lifecycle Audit — Enumerate globally tracked users and correlate their identities to internal virtual tenants to ensure accurate cross-tenant access control
- Tenant Discovery — Query the strict virtual boundaries natively splitting tenant data to isolate exact SaaS tenant IDs before performing deep data inspections
- Metadata Retrieval — Deep-dive into specific Database endpoints to retrieve precise structural representations and operational state vectors instantly
How it works
- Subscribe to this server
- Enter your Nile API URL and API Key
- Start managing your multi-tenant infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- SaaS Developers — provision new B2B tenants and verify database isolation through natural conversation without manual CLI scripts
- Database Engineers — monitor storage exhaustion and active connection counts across multiple Nile databases directly from your workspace
- Backend Architects — audit user identity mappings and manage tenant-specific data sharding efficiently to maintain high-scalability standards

Why CrewAI?
When paired with CrewAI, Nile (PostgreSQL for Multi-Tenant Apps) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Nile (PostgreSQL for Multi-Tenant Apps) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
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.
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.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
