Enrich accounts with OpenAI Agents SDK

Deploy an agent that takes a raw domain and pulls full firmographics using `find_company`. You get employee counts, funding rounds, and tech stacks routed straight into your OpenAI tracing dashboard. When your primary agent detects a high-value target, it hands off the payload to a specialized research agent. That second agent runs `get_prospects` to pull key decision-makers based on role and seniority.

Map decision makers automatically

Feed a list of raw email addresses into your agent system and watch it execute `find_person_and_company`. The model maps out the exact corporate structure behind that single contact. Built-in guardrails ensure the agent validates the email format before making the MCP call. If a contact looks suspicious, the system can trigger `find_risk` to calculate fraud probability before routing the lead to sales.

Turn anonymous IP traffic into pipeline

Hook up your web logs to an OpenAI agent and let it run `reveal_ip` on every visitor. The model identifies the exact corporate network browsing your site. From there, the agent can automatically ping the `autocomplete_company` tool to clean up the company name and format it for your CRM. All these MCP tool calls are logged and visible in your OpenAI dashboard for debugging.

Setup guide

Set up Clearbit (HubSpot) 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 Clearbit (HubSpot) tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Clearbit (HubSpot) 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="Clearbit (HubSpot) Agent",
            instructions="You have access to Clearbit (HubSpot) tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Clearbit (HubSpot) MCP in OpenAI Agents SDK

Install the openai-agents package via pip. Initialize the MCP Server using MCPServerStreamableHttp with your Vinkius endpoint url. Pass that server instance into your agent's constructor using the mcp_servers array.

It handles them natively. You can have a frontend agent collect an email, then hand that data off to a backend agent. That second agent executes the find_person tool to append social profiles and job titles.

You define exact constraints in the agent's instructions. If you only want the model to use get_watchlist, you set a guardrail rule preventing it from calling the other endpoint functions.

We handle the authentication and hosting. You get a single endpoint token to pass to your agent, and we run the server in an ephemeral V8 Isolate sandbox.

Your agent reads corporate domains, email addresses, and IP logs. Vinkius processes these requests through a zero-trust architecture where the container spins up, runs the query, and immediately destroys itself.
