Quantify Engagement Value

This MCP gives your agent the `get_engagement_valuation` tool. It's the first link in your analysis chain, turning fuzzy engagement metrics into a concrete Earned Media Value (EMV) figure. Your agent doesn't just get a number; it gets a structured output ready for the next step. This is how you start building a business case for a campaign, grounded in an objective valuation of its reach and interaction quality.

Analyze True Profitability

The next link in the chain connects marketing activity to the bottom line. With the `get_conversion_economics` tool, your agent takes campaign costs and sales data to calculate the actual Customer Acquisition Cost (CAC) and profitability. This moves the analysis from potential value to realized profit. The agent can now reason about whether a high-engagement campaign actually drove profitable growth or just generated expensive clicks.

Benchmark Against Paid Social

Here's the final decision point. An agent armed with the `compare_to_paid_social` tool can weigh the influencer campaign's performance against your established paid social benchmarks. It’s a direct, numbers-to-numbers comparison of efficiency. This is how you automate budget allocation decisions. The chain’s output isn't a report; it's a clear recommendation, backed by a transparent sequence of calculations performed by this MCP Server.

Setup guide

Set up Influencer ROI Calculator 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 Influencer ROI Calculator 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({
    "influencer-roi-calculator-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 Influencer ROI Calculator transactions"
    })
    print(result["messages"][-1].content)

Common questions about Influencer ROI Calculator MCP in LangChain

You design a chain where the output of one tool call informs the input of the next. For example, use the campaign ID from `get_engagement_valuation` to then call `get_conversion_economics`, and finally pass the resulting CAC to `compare_to_paid_social`.

Yes. You can build a chain that runs the same analysis in parallel for multiple influencers. The agent can then compare the final profitability and benchmark scores to recommend which partner offers a better return.

Since every tool call made through this MCP is a distinct step in your chain, LangSmith automatically traces it. You can see the exact inputs, outputs, latency, and costs for each calculation, giving you full visibility into your agent's reasoning.

Yes. When you initialize your agent, you pass it a list of available tools. Simply provide only the specific tool you want it to use, like `get_conversion_economics`, and it won't have access to the others on this MCP.

Your data is processed ephemerally. The Influencer ROI Calculator MCP receives inputs for a calculation and returns the result without storing your campaign costs or conversion metrics. LangChain's session management is handled on your end, giving you control over context persistence.
