Perplexity

Build multi-step deal pipelines.

You use `get_sales_contact_details` to verify a prospect's information. Then, the agent uses that contact ID to call `create_sales_deal`, automatically building out the new opportunity. This chain lets your AI client decide the right sequence of actions—first getting data, then using it to create or update records in Zendesk Sell.

Automate lead qualification and updating.

Start by invoking `list_sales_leads` to pull a list of potential accounts. Next, the agent can call `get_lead_details` on specific entries to check for required data. Finally, if the information is good, it uses `update_existing_deal` to push the fresh details back into Zendesk Sell.

Manage full contact lifecycle chains.

A common task involves gathering all potential prospects. You first call `list_sales_contacts`, then use `create_new_lead` if a new name pops up. The resulting chain ensures that every step, from listing to creation, is handled sequentially and logged for review.

Setup guide

Set up Zendesk Sell 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 Zendesk Sell 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

async with MultiServerMCPClient({
    "zendesk-sell-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 Zendesk Sell transactions"
    })
    print(result["messages"][-1].content)
