How to Use the HubSpot Operations Hub MCP in LangChain

Q: Can LangChain verify HubSpot Operations Hub property groups before creation?

Yes, you use hslistpropertygroups to validate the destination group for any new field. This ensures your custom properties land in the correct UI section, keeping your CRM interface organized.

Q: How do I audit HubSpot Operations Hub workflows using LangChain?

You call hslistworkflows to get a status report on all active automations. Your agent then parses the action counts and enabled status to flag inactive or problematic processes.

Chain HubSpot Operations Hub tools directly into your LangChain agents for automated CRM data management and pipeline orchestration.

Perplexity

Automate CRM data model expansion

Add custom fields to your CRM objects without leaving your development environment. By using `hs_create_property` inside your agentic chains, you ensure that new data requirements are met instantly as your business logic evolves. Your agents can check existing structures first using `hs_list_properties` and `hs_list_property_groups`. This prevents duplicate entries and keeps your CRM data model clean and predictable.

Sync pipeline logic with LangChain

Pull live stage data into your execution flow using `hs_list_all_pipelines`. You get the exact internal IDs and display orders needed to map your automated deal routing logic directly to HubSpot. This visibility allows your agents to dynamically adjust processes based on current pipeline states. You reduce manual configuration errors by relying on real-time data retrieved directly through the MCP server.

Manage user assignments

Feed current owner details into your decision logic with `hs_list_owners`. Your agents can identify available team members and assign records accurately based on real-time status and team membership. By chaining this tool with your internal assignment rules, you build robust routing systems. You eliminate the need for hardcoded user IDs that break whenever your team structure changes.

Setup guide

Set up HubSpot Operations Hub MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes HubSpot Operations Hub tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "hubspot-operations-hub-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent HubSpot Operations Hub transactions"
    })
    print(result["messages"][-1].content)
