What you can do with this MCP connector
Nubarium gives your AI agent direct access to Mexican corporate records and national identity data. When you connect this server, your agent runs deep due diligence against authoritative Mexican sources without needing a manual portal login. It's built for risk managers and compliance teams who need hard facts fast.
Validating Personal Identity Records
You can confirm if a person’s CURP is active and pull associated personal metadata using validate_mex_curp. This tool retrieves details like names or birth locations linked to the identifier. To check tax status, you use validate_mex_rfc, which verifies both individual and business RFC numbers and returns comprehensive, up-to-date tax profiles for that entity.
Researching Corporate Entities
You can start by querying the directory with search_mex_companies to pull a list of potential Mexican businesses based solely on a name string. Once you have an ID, you get all available details—a full corporate dossier—by calling get_mex_company_details. This provides a complete view of the company’s status and history.
Verifying Legal Links (Due Diligence)
The most critical check is verifying legal representation. You use validate_mex_legal_representative to confirm if an individual is officially linked as a representative for a specific corporate entity, cross-referencing both their RFC and CURP against the company's records.
Monitoring Usage
For operational visibility, you can check your API consumption limits using get_api_usage. This reports the current usage metadata so you know exactly how much research volume your agent is generating.
It's simple: You just ask the agent questions in plain English. It handles all the function calls behind the scenes. Don't worry about complicated data structures; just give it names, IDs, and concepts, and your AI client runs the necessary checks.
How Nubarium MCP Works
- 1 Subscribe to the Nubarium MCP Server and input your unique API key.
- 2 Connect your preferred AI client (Claude, Cursor, etc.) to the server via the MCP protocol.
- 3 Instruct your agent with natural language queries (e.g., 'Validate this RFC'). The agent executes the necessary tool calls using the stored credentials.
The bottom line is you get validated Mexican data directly in chat, without leaving your AI client.
Who Is Nubarium MCP For?
Anyone who needs to verify legal status or corporate background on Mexican entities. This is for Compliance Officers running daily KYC checks; Risk Managers needing immediate due diligence before a transaction; and Data Analysts automating regional tax ID audits that would otherwise take days of manual portal work.
Uses validate_mex_curp and validate_mex_rfc to ensure all clients meet local identity standards before onboarding.
Employs the server to check corporate backgrounds (get_mex_company_details) and verify legal representative status for high-risk accounts.
Automates large-scale checks, using search_mex_companies followed by targeted API calls to build datasets of regional tax IDs.
What Changes When You Connect
- Complete Compliance Checks: Use
validate_mex_curpandvalidate_mex_rfcto instantly audit identity IDs. You get confirmation that the data is accurate, saving days of manual portal work. - Deep Corporate Dossiers: Don't just get a name match. Run
get_mex_company_detailsafter usingsearch_mex_companiesto pull an entire corporate history for due diligence. - Confirm Legal Status: Use
validate_mex_legal_representativeto prove who runs the company. This is crucial; you verify the link between a person and the entity, not just their IDs. - Speed Over Manual Portals: Your agent handles all the complex lookup logic. You don't open six different government websites—you ask one question in chat.
- Track Usage Effortlessly: Run
get_api_usageto monitor your research volume and keep strict control over API consumption, which is vital for large-scale data analysis.
Real-World Use Cases
Onboarding a new partner in Mexico
The risk manager needs to onboard 'Acme Corp.' They first run search_mex_companies by name. Once they get the ID, they use get_mex_company_details. Finally, they verify the primary signatory using validate_mex_legal_representative, ensuring all compliance checks pass before signing a contract.
Auditing a suspect tax profile
A data analyst suspects an individual's tax status. They start by running validate_mex_rfc with the known ID. This confirms if the RFC is active and retrieves the full tax regime metadata, solving the problem of incomplete public records.
Verifying a client's personal identity
A compliance officer gets a new lead. They use validate_mex_curp with the provided ID and name. The tool validates the CURP and returns detailed birth information, instantly confirming if the person is who they claim to be.
Due diligence on an unknown entity
A user needs to know everything about 'Soluciones Tech'. They run search_mex_companies to get a list of potential matches, then pick the most likely ID and execute get_mex_company_details. This gives them a full corporate picture in one sequence.
The Tradeoffs
Assuming IDs are enough
A user runs only validate_mex_rfc and assumes the company is legitimate. They miss checking who actually holds legal authority.
→
You must follow up with validate_mex_legal_representative. This confirms that the RFC owner is genuinely authorized to act for the corporate entity, adding a critical layer of security.
Running searches too vaguely
Trying to validate an identity without first confirming if they are associated with a known company profile.
→
Always use search_mex_companies first. Getting a company ID helps narrow the scope, allowing you to run targeted checks like validating the representative using validate_mex_legal_representative.
Ignoring usage limits
Running hundreds of validation calls back-to-back without checking consumption.
→
Before massive data pulls, run get_api_usage. This lets you monitor your current API quota and prevents unexpected service interruptions mid-workflow.
When It Fits, When It Doesn't
Use this server if your workflow requires official Mexican identity (CURP) or tax ID (RFC) verification. If your goal is simple, general research—like finding a company by name alone—you can start with search_mex_companies. But if you need to know the legal status of that company or who signed off on it, you must run the deeper tools: get_mex_company_details and validate_mex_legal_representative. Don't use this if you just need a list of names; use it when you need proof backed by Mexican governmental data. The server handles the complexity; you focus on the compliance outcome.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 6 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Checking corporate background shouldn't require six different government portals.
Today, running due diligence is a nightmare of manual tabs. You start by searching an official company registry, then open another portal to check the Tax ID (RFC), and maybe a third one just to see who the legal representative is. It's copy-paste hell—and you lose track of which data point came from where.
With Nubarium, your agent runs that whole sequence in milliseconds. You ask it: 'What's the status of Acme Corp?' And it returns a single answer, pulling company details (using `get_mex_company_details`), verifying its tax ID (`validate_mex_rfc`), and confirming representation—all without you ever leaving the chat window.
Nubarium: Get full corporate records with get_mex_company_details.
Before this server, getting a comprehensive picture of a company meant piecing together five or six disparate data points from different government sources. You'd end up with incomplete dossiers that were hard to trust.
Now you get the full dossier. The `get_mex_company_details` tool gathers all relevant corporate metadata in one call, giving you maximum context and minimum friction. It’s the single source of truth for Mexican business intelligence.
Common Questions About Nubarium MCP

Use validate_mex_rfc. This checks the RFC (Tax ID) for both individuals and businesses, providing comprehensive and current tax profile data.
Can I only search companies by name using search_mex_companies? +
Yes. The search_mex_companies tool takes a name string as input to locate potential matches across the directory, which you then refine with get_mex_company_details.
How does validate_mex_legal_representative work? +
