How to Use the BrandMentions MCP in LangChain

Q: How does BrandMentions work with LangChain for keyword tracking?

You plug the server into your agent, and it triggers postsearch for your keywords. LangChain then routes those mentions into your database or analysis workflow.

Q: Can BrandMentions data influence LangChain agent decisions?

Yes. The agent reads getprojectmentions and adjusts its next action if the volume of negative feedback spikes. It makes decisions based on real-time data.

Q: How do I check my usage within a LangChain agent?

Call getremainingcredits as part of your startup sequence. The agent verifies your balance before it initiates any search tasks.

Build multi-step reasoning chains in LangChain that track brand sentiment and influencer activity automatically.

Chain social monitoring with LangChain

Feed `get_mentions` output directly into your LangChain agent's next logic step. You define the flow, and the agent pulls search results based on the previous chain's conclusion. Use `list_projects` to identify which campaign to query first. The agent then selects the right tool, ensuring your chain stays focused on live data.

Automate project management tasks

Create new tracking jobs using `add_project` inside your LangChain pipeline. It handles the setup so you can move on to analyzing the data. Delete outdated campaigns with `delete_project` once the pipeline finishes. This keeps your account clean and your token usage predictable.

Trace tool calls for better debugging

Monitor every `post_search` execution through LangSmith. You see exactly what the agent requested and how long it took to get the data back. Check `get_remaining_credits` before starting a heavy chain. It prevents your agent from hitting limits mid-process, keeping your production pipelines stable.

Setup guide

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