Chain email workflows in LangChain

Feed `get_contacts` output directly into `add_list_memberships` to automate your subscriber management. Your agent handles the logic between steps without manual intervention. This MCP Server lets you link `create_campaign` results with `schedule_campaign` inside your chains. You control the flow of data through every node.

Monitor campaign performance

Pipe `get_campaign_opens` and `get_campaign_clicks` data into your LangSmith traces for real-time visibility. You see exactly how your audience interacts with every message. Use `get_campaign_bounces` to trigger follow-up cleanup tasks. Your agents resolve delivery issues before you even open the dashboard.

Manage lists with logic

Apply `add_tags_to_contacts` based on complex conditions defined in your agent's system prompt. You keep your database clean without writing custom middleware. Execute `bulk_delete_contacts` or `update_contact` when your chain detects stale records. This keeps your marketing lists accurate and lean.

Setup guide

Set up Constant Contact Alternative 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 Constant Contact Alternative 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.
