Audit Mexican Tax IDs inside Claude Desktop

Your AI client uses `validate_mex_rfc` to verify Mexican tax IDs directly inside Claude Desktop. Drop a raw RFC into the chat to check the registered business name, activity status, and postal code. If you need to verify signing authority, ask Claude Desktop to trigger `validate_mex_legal_representative`. It cross-references the RFC against the representative's CURP to confirm legal status on the spot.

Search Mexican Corporate Records on the Fly

Your agent calls `search_mex_companies` to locate Mexican businesses by name inside Claude Desktop. When you are researching suppliers or partners, paste a partial company name to find matching entities. You do not have to navigate slow government portals or copy-paste data between tabs when this MCP Server is active in your chat.

Track Your API Usage and Identity Verifications

Your desktop client executes `get_api_usage` to track your verification volume and remaining balance. Keep tabs on your query counts directly from the chat window. For individual identity checks, feed a CURP to the chat window. The desktop app uses this MCP connection to invoke `validate_mex_curp` and verify details against official registry records.

Common questions about Nubarium MCP in Claude Desktop

Open your `claude_desktop_config.json` file and add the server configuration under the `mcpServers` block with your API credentials. Restart the Claude Desktop app, and you will see the tools ready to use via the hammer icon in the chat input.

Yes, you can add this MCP Server as a custom connector in the settings of claude.ai. Just paste the remote server URL hosted by Vinkius and authenticate to use the verification tools in your browser.

If a CURP or RFC is formatted incorrectly, the tool returns the specific validation error directly to Claude Desktop. The agent then explains the formatting error in the chat so you can correct the tax ID or identity number.

You need an active Vinkius subscription to access the hosted server endpoint. Once connected, your Claude Desktop client can call all six verification tools using a single secure token.

All identity verification requests are processed through secure, ephemeral V8 sandboxes that do not store the CURP, RFC, or corporate details. Your queries are sent directly to the official Mexican databases and wiped from the execution environment immediately after Claude Desktop receives the response.
