How to Use the Daktela MCP in LangChain

Q: Can I trace Daktela tool inputs inside LangSmith with LangChain?

Yes. Every time your LangChain agent invokes listcallhistory or getticket, the exact arguments and JSON payloads show up in your LangSmith dashboard. You can debug agent decisions and track latency for every single CRM query.

Feed Daktela call histories and tickets directly into your LangChain reasoning loops to resolve customer issues in one pass.

Build multi-step Daktela tickets with LangChain

Connect your LangChain ReAct agents directly to your support queue using this MCP Server, powered by `list_tickets` and `get_ticket`. The agent takes the output from the first step and feeds it directly into `create_ticket` to assign tasks to the right department. You trace every single tool call and state transition inside LangSmith to see exactly why an agent chose a specific queue.

Sync CRM contacts on the fly

When a call ends, your chain pulls the log via `list_call_history` and checks it against existing records with `list_contacts`. This isn't just a simple script. LangChain manages the flow so that if `create_contact` fails, the agent backtracks, checks `list_users` to find an active manager, and routes a notification immediately.

Analyze customer journeys across Daktela queues

Feed your LangChain sequential chains with a complete picture of customer touchpoints by calling `list_email_history` and `list_activities` in parallel. By combining these tools, your agent evaluates queue load using `list_queues` and redirects high-value accounts to shorter lines. You get a live, context-aware routing system built on raw API outputs.

Setup guide

Set up Daktela 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 Daktela 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({
    "daktela-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 Daktela transactions"
    })
    print(result["messages"][-1].content)

Common questions about Daktela MCP in LangChain

LangChain agents use custom runnable backoff wrappers when calling `list_tickets` or `create_ticket`. This keeps your LangChain agents from hitting API rate ceilings when processing hundreds of support tickets.

Yes. Every time your LangChain agent invokes `list_call_history` or `get_ticket`, the exact arguments and JSON payloads show up in your LangSmith dashboard. You can debug agent decisions and track latency for every single CRM query.

You initialize the MultiServerMCPClient with the Daktela endpoint URL alongside your other servers. LangChain then aggregates the tools so your agent can pull data from Daktela and write it to another system in a single chain.

Vinkius manages the connection details and provides a single secure endpoint token. You pass this token to your local client, meaning you never expose your actual contact center credentials to the LLM or your local environment.

Your customer CRM contacts and call histories run through a secure V8 Isolate sandbox on Vinkius. No data is stored on our servers; the MCP server acts as an ephemeral proxy that only passes API payloads directly to your local runtime.
