What is the Nubarium MCP Server?
Empower your AI agent to orchestrate your entire Mexican identity and corporate research workflow with Nubarium, the leading platform for Mexican data intelligence. By connecting Nubarium to your agent, you transform complex national lookups into a natural conversation. Your agent can instantly validate RFC (Tax ID) and CURP (Identity ID) records, audit company profiles, and verify legal representative status without you ever touching a manual portal. Whether you are conducting KYC checks or regional due diligence, your agent acts as a real-time institutional analyst, ensuring your Mexican data is always verified and up-to-date.
What you can do
- Identity Auditing — Validate Mexican CURP records and retrieve detailed personal metadata, including names and birth details.
- Tax Oversight — Verify RFC registration status and retrieve comprehensive tax profiles for individuals and businesses.
- Corporate Discovery — Search for Mexican companies by name and retrieve detailed dossiers to understand organizational status.
- Compliance Intelligence — Verify the link between legal representatives and companies to assist in due diligence.
- Operational Monitoring — Check API usage metadata to maintain strict control over your research volume.

Why CrewAI?
When paired with CrewAI, Nubarium becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Nubarium 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 do I find my Nubarium API Key?
Log in to your Nubarium dashboard, and you will find your API Key under the 'API Settings' or 'My Keys' section. Copy and paste it below.
Can the agent validate Mexican tax IDs (RFC)?
Yes. Use the validate_mex_rfc tool providing the RFC string. Your agent will verify its status with official sources instantly.
Is CURP validation supported for individuals?
Yes. The validate_mex_curp tool allows your agent to check the identity status of individuals in Mexico using their unique CURP ID.
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.
