How to Use the Salesforce Marketing Cloud MCP in LangChain

Q: How does the agent handle campaign member additions?

The agent invokes sfaddcampaignmember using the specific contact or lead ID. You define the logic in your chain to ensure the right people land in the right campaigns.

Build automated campaign pipelines in LangChain by connecting your Salesforce Marketing Cloud data directly into your reasoning chains.

Chain campaign operations for automated workflows

Feed live campaign data directly into your LangChain sequences. You can trigger `sf_create_campaign` based on external events, then immediately route that campaign ID into other logic blocks without manual intervention. This setup removes the middleman between your data and your agent. Your chains now react to real-time Salesforce Marketing Cloud metrics as they happen in your environment.

Measure ROI through agentic reasoning

Your agent queries `sf_campaign_performance` to evaluate channel efficacy on the fly. It links these metrics to downstream tasks, ensuring your budget allocation logic is always grounded in current data. Stop guessing which initiatives work. By piping `sf_campaigns_by_status` results into your LangSmith traces, you gain full visibility into how your agent arrived at its marketing decisions.

Maintain granular control over member lists

Directly update your audience segments by chaining `sf_add_campaign_member` calls. Your LangChain agent handles the logic of who gets added to which campaign based on custom triggers you define. This MCP server ensures every member addition is logged and traceable. You aren't just sending data; you're building a verifiable history of engagement within your Salesforce Marketing Cloud instance.

Setup guide

Set up Salesforce Marketing Cloud 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 Salesforce Marketing Cloud 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({
    "salesforce-marketing-cloud-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 Salesforce Marketing Cloud transactions"
    })
    print(result["messages"][-1].content)
