How to Use the Nubarium MCP in OpenAI Agents SDK

Q: How does Nubarium handle legal representative verification in OpenAI Agents SDK?

The agent calls validatemexlegalrepresentative with the target RFC and CURP. It returns a boolean status indicating whether the individual holds legal power of attorney for that business.

Q: How do I track my request volume?

Use getapiusage to query your current call volume directly from the agent. This tool returns real-time metrics so your agent can alert you before you hit your subscription limits.

Audit Mexican businesses with OpenAI Agents SDK

The `search_mex_companies` tool lets your agent find registered entities in Mexico by name before fetching full details. This tool prevents your workflows from processing invalid or unregistered businesses by running checks against official records at the start of your pipeline. Once a business is located, the agent runs `get_mex_company_details` to verify corporate registration numbers, official addresses, and operational status. Because the OpenAI Agents SDK handles agent handoffs, you can route these raw lookups to a specialized compliance agent without writing manual routing logic.

Verify RFC and CURP tax IDs automatically

The `validate_mex_rfc` tool checks Mexican taxpayer identification numbers against live government databases to confirm they exist and are active. This tool stops fraudulent onboarding dead in its tracks by forcing your agent to verify tax statuses before proceeding with any financial transactions. For individual verification, the agent runs `validate_mex_curp` to pull official registration details and match them against user-provided profiles. The built-in guardrails in this MCP Server setup let you intercept the agent's decisions if the tax ID returns a flagged or inactive status.

Validate legal reps with this MCP Server

The `validate_mex_legal_representative` tool checks if a specific CURP is legally authorized to represent a given RFC. This tool solves the headache of manual corporate power-of-attorney checks by letting your agent verify signing authority instantly. You can monitor the volume of these checks across your pipeline using `get_api_usage` to keep tabs on your billing limits. The OpenAI dashboard tracks every single tool call, giving you a clear view of how your agents handle sensitive corporate verification tasks.

Setup guide

Set up Nubarium MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Nubarium tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Nubarium tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Nubarium tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Nubarium Agent",
            instructions="You have access to Nubarium tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Nubarium MCP in OpenAI Agents SDK

Install the SDK using pip and instantiate MCPServerStreamableHttp with your connection URL. Pass this MCP Server object into your agent constructor to let your agent discover the identity tools.

Yes, set the caching parameter to true in your agent configuration to avoid fetching the tool definitions on every turn. This keeps your validation pipelines fast when querying Mexican corporate data.

The agent calls `validate_mex_legal_representative` with the target RFC and CURP. It returns a boolean status indicating whether the individual holds legal power of attorney for that business.

Use `get_api_usage` to query your current call volume directly from the agent. This tool returns real-time metrics so your agent can alert you before you hit your subscription limits.

Your OpenAI Agents SDK pipeline sends RFC and CURP queries through an ephemeral sandbox that never stores the raw payload. All transit is encrypted, ensuring that sensitive Mexican tax and identity records are immediately discarded after validation.
