Perplexity

Extract lead details from million-token contexts

The `create_hubspot_lead` tool allows Gemini models to scan massive chat logs or documents and extract contact details. Because the model holds huge contexts, it can locate an email or phone number mentioned pages back. The tool then structures this data to create a clean contact. Look, if you're dealing with enterprise clients, you can't afford to miss these details. You implement this by wrapping your Vinkius HTTP endpoint in the `McpToolset` class. This lets your enterprise agent run the tool directly when it detects relevant lead details inside your Google Cloud environment.

Connect Google ADK to HubSpot using secure transport

The `create_hubspot_lead` tool supports both Stdio and HTTP transport layers. This flexibility lets you run your agent inside isolated Google Cloud environments while maintaining a secure outbound connection to your CRM via the MCP Server. You can restrict the toolset to expose only this specific write action by passing a tool name filter. This ensures your agent cannot access other endpoints, maintaining a tight security perimeter around your cloud architecture.

Combine BigQuery data with your MCP Server pipeline

The `create_hubspot_lead` tool fits right into your existing Google Cloud data pipelines. Your agent can read customer profiles from BigQuery, process them using Vertex AI, and immediately write the qualified leads to HubSpot. This setup removes the need for custom ETL scripts. By using the standard MCP, your agent handles the data transformation and CRM entry in a single execution step.

Setup guide

Set up HubSpot Lead Creator MCP in Google ADK

Prerequisites

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

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with HubSpot Lead Creator tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="HubSpot Lead Creator_agent",
    model="gemini-2.0-flash",
    instruction="You have access to HubSpot Lead Creator tools via MCP.",
    tools=mcp_tools,
)
