How to Use the FirstQuadrant MCP in LangChain

Q: How do I connect the FirstQuadrant Alternative MCP Server to a LangChain agent?

Install langchain-mcp-adapters and initialize the MultiServerMCPClient with your Vinkius HTTP endpoint. Pass the tools retrieved from client.gettools() directly into your agent constructor to let it run campaign tasks.

Q: Can I trace FirstQuadrant Alternative tool calls inside LangChain?

Yes, every tool call like runcampaign or enrichcontact is fully visible in LangSmith. You can inspect the exact payload, latency, and token usage for every step of your outbound sequence.

Q: How does this FirstQuadrant Alternative MCP Server integration handle failing campaigns?

Your agent can call getlogs or gethealth when a step fails. It uses this real-time data to decide whether to stop a sequence or alert your team.

Q: Can I run multiple campaigns simultaneously with this setup?

Yes, you can trigger runcampaign for different lists in parallel. The underlying server handles the execution queue, while your agent tracks the status of each run.

Run multi-step outbound campaign chains in LangChain with real-time contact enrichment and system logging.

Chain contact enrichment with live campaign runs

`enrich_contact` pulls raw external data to update prospect profiles before triggering any outreach sequences. Your LangChain agent handles this by feeding the output of the enrichment step directly into `create_campaign_sequence`. It keeps your pipeline moving without manual copy-pasting. You can monitor the entire chain execution via LangSmith tracing. If a sequence fails, the agent checks `get_logs` to isolate the issue immediately. This keeps your outbound flow running on clean data and clear logic.

LangChain agents manage campaigns on autopilot

`run_campaign` executes active outbound sequences based on real-time triggers from your LangChain decision loops. The agent evaluates intermediate response metrics, then decides whether to execute a sequence or call `hard_stop_campaign` to prevent spamming. This setup lets you build autonomous sales loops that adjust on the fly. If email deliverability drops, your agent reads `get_health` to verify server status before pushing more contacts into the queue.

Sync CRM webhooks directly into your LangChain pipelines

`receive_hubspot_webhook` captures live CRM events to update your LangChain agent's state instantly. When a deal stage changes, the agent triggers `create_deal` or `update_deal` to keep your records aligned. The MCP Server handles the incoming payloads, letting your chains react to Stripe, Nylas, or HubSpot events in milliseconds. You do not need to write custom webhook receivers or poll APIs.

Setup guide

Set up FirstQuadrant 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 FirstQuadrant 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({
    "firstquadrant-alternative-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 FirstQuadrant transactions"
    })
    print(result["messages"][-1].content)
