How to Use the MaestroQA MCP in LangChain

Q: Can my LangChain agent filter which MaestroQA tickets it reviews?

Yes. The listqatickets tool accepts optional parameters for filtering. Your agent decides which parameters to pass based on the prompt context.

Q: How does LangChain handle the async MaestroQA data exports?

Your chain triggers requestqadataexport with a start and end date. You can build a LangGraph loop that periodically checks getexportdownloadlinks until the raw data is ready.

Build ReAct agents that audit customer support workflows with LangChain and the MaestroQA MCP Server.

Pipeline-driven QA Extraction with LangChain

Connect LangChain to your support stack. Your agent pulls recent interactions using `list_qa_tickets` and checks the evaluation criteria via `list_qa_rubrics`. The output of one tool feeds directly into the next. You can trace the exact latency and token usage in LangSmith when the chain calls `get_ticket_qa_details` to extract specific grader comments.

Asynchronous Data Export Chains

Running massive performance reports usually breaks synchronous scripts. This MCP Server handles it by letting your agent trigger `request_qa_data_export` with specific date ranges. The chain pauses, waits for the async job to finish, and follows up with `get_export_download_links`. You get reliable data pipelines without writing custom polling logic.

Automated CSAT Syncing

Support teams often keep CSAT scores in a completely different database than their QA metrics. Your ReAct agent can bridge that gap by executing `push_csat_scores` after reading from your external CRM. This builds a unified view of agent performance. You track the exact inputs and outputs of every sync operation, giving you full observability over how your customer feedback reaches MaestroQA.

Setup guide

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