Chain Appier Analytics in LangChain

The `get_campaign_analytics` tool feeds raw performance metrics straight into your ReAct agents. Your LangChain setup evaluates the numbers, decides if a campaign is underperforming, and passes that context to the next link in the chain. You get full observability through LangSmith. Every time the agent checks ad spend or pulls conversion rates, you see the exact token usage and latency. It turns black-box marketing reports into trackable, debuggable agent workflows.

Feed Audience Data to MCP Servers

Calling `list_audiences` and `list_segments` lets your agent identify exactly who is seeing your ads. You build a pipeline that cross-references these Appier segments against your internal customer database tools. The agent decides which segment needs attention based on intermediate results. If a specific demographic shows poor engagement, the agent automatically triggers `get_audience` to dig deeper before generating a new copy strategy.

Automate Conversion Reasoning

Using `list_predictions` and `list_conversions` gives your code direct access to Appier's predictive models. Your agent pulls the expected conversion rates and compares them against actual tracked events. This setup handles the heavy lifting of marketing analysis. Instead of manually exporting CSVs, your multi-step MCP pipeline reads the prediction data, evaluates the reality, and outputs a formatted action plan.

Setup guide

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

Common questions about Appier MCP in LangChain

Install the langchain-mcp-adapters package and use MultiServerMCPClient. Pass your Vinkius endpoint URL and call client.get_tools() to bind the marketing tools to your agent.

Yes. The agent reads your prompt and decides the execution order. It might call list_campaigns first, then run get_campaign on specific IDs it finds.

No. Vinkius handles the underlying API keys. You just pass your single Vinkius MCP endpoint token into the client configuration.

Enable LangSmith tracing in your environment. It logs the exact inputs and outputs every time your agent requests campaign details.

Your audience segments and conversion events stay protected inside a V8 Isolate Sandbox. Vinkius spins up the connection ephemerally just for the tool call and destroys it immediately after the data returns.
