Chain Dev.to (Forem) actions in LangChain

Connect `list_articles` to your logic chains to process community content in real-time. Your LangChain agent evaluates the output, decides the next step, and moves through your pipeline without manual intervention. Pass the result of one tool into another to automate drafting or auditing. You link `get_article_by_id` with `update_article` to refine posts based on specific feedback loops you define in your code.

Observe Dev.to (Forem) tool calls

Trace every interaction your LangChain agent has with the Forem platform. You see exactly what data enters and leaves `list_my_articles` or `get_me` within your standard execution logs. Debugging becomes a matter of checking your trace history. You identify why a specific post update failed or how an article list was generated by inspecting the inputs and outputs of every MCP tool call.

Aggregate multi-server context

Combine your Dev.to (Forem) tools with other data sources in a single LangChain environment. Your agent pulls user data via `get_user` and checks internal databases to cross-reference contributor activity. Everything happens in one workspace. You define how the agent weighs API responses against your own documents to make informed decisions about content publishing or moderation.

Setup guide

Set up Dev.to (Forem) 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 Dev.to (Forem) 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({
    "devto-forem-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 Dev.to (Forem) transactions"
