How to Use the Dryfta MCP in LangChain

Q: How do I handle Dryfta API limits when running LangChain agents?

Your LangChain agent can query getdryftaaccountmetadata to check current API limits before running large batch operations. This allows the LangChain chain to pause or back off to stay within Dryfta thresholds.

Q: Can I trace Dryfta session checks in LangChain?

Yes, every LangChain call to listupcomingsessions or getsessiondetails is recorded automatically inside your LangChain LangSmith dashboard. You see the exact raw JSON returned from the Dryfta API directly in your LangChain trace.

Q: How does LangChain manage state when retrieving Dryfta exhibitor lists?

You can use listeventexhibitors within a persistent LangChain session to keep track of retrieved Dryfta sponsors across multiple steps. This prevents your LangChain agent from processing the same Dryfta exhibitor twice.

Run multi-step Dryfta event management chains and trace every tool call using LangChain.

Run Dryfta attendee audits with LangChain agents

The `quick_event_enrollment_audit` tool feeds Dryfta registration counts directly into your LangChain decision chain. Your LangChain agent evaluates these Dryfta volumes to determine if the next link in the chain should trigger. If registration thresholds are met, the LangChain pipeline immediately executes `get_attendee_details` to pull specific Dryfta profiles. This sequence ensures your LangChain application processes Dryfta attendee data dynamically based on live event metrics.

Validate Dryfta abstracts and sessions in LangChain

Your LangChain routing agent uses `list_submitted_abstracts` to retrieve pending Dryfta paper submissions for evaluation. Once evaluated, the LangChain chain runs `list_event_sessions` to match accepted Dryfta abstracts with open schedule slots. This multi-step LangChain reasoning pipeline automates Dryfta scheduling based on live submission data. You can monitor this entire Dryfta scheduling chain using LangChain's LangSmith tracing to verify tool inputs and outputs.

Target Dryfta communications via MCP Server tools

To locate specific Dryfta registrants, your LangChain agent executes the `search_attendees_by_keyword` tool. The LangChain agent then feeds the search results directly into `get_attendee_details` to verify Dryfta registration status. This specific tool sequence allows your LangChain application to target Dryfta communications without pulling the entire database. Using this MCP Server setup, your LangChain workflow manages Dryfta attendee data with high precision.

Setup guide

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