How to Use the Vercel MCP in LangChain

Q: How does LangChain use the Vercel MCP Server to list projects?

Your agent calls listprojects directly. It gets an array containing names and IDs for every project in your account. This information feeds into subsequent steps in your chain.

Q: Can I use the Vercel MCP Server with LangChain to trigger builds?

Yes. By invoking triggergithubdeployment, you pass the target project name and the specific Git ref. The output confirms the build request, allowing your agent to proceed knowing the action was taken.

Q: If I'm building an app with Vercel and LangChain, how do I check domain aliases?

Use listprojectaliases. This tool lists all specific subdomain routing mappings for a given project. You can then parse this output to confirm your intended traffic flow.

Q: What data does the Vercel MCP Server expose regarding project configuration?

The server exposes detailed configuration via getprojectdetails. This includes setup parameters, domain mappings, and associated deployment statuses for a specific project.

Control Builds with LangChain

Need to stop a messy deployment? You can abort an ongoing build using `cancel_active_build`. This is perfect for testing or when a project isn't ready yet. It also lets you initiate manual builds via `trigger_github_deployment`, passing both the project name and the specific Git reference. This keeps your agent in control of the entire CI/CD lifecycle.

Inventory Your Vercel Setup

The MCP Server gives you a full view of what's running. Use `list_projects` to see every account project, or use `get_project_details` to pull deep config for one specific setup. Want to know about domains? You can run `list_account_domains` to check high-level apex domains managed by Vercel. It's a quick way to audit your infrastructure.

Manage Project Structure

Setting up new services is easy. Call `create_project`, giving it a name and the required framework slug. If you need to clean house, remember that `delete_project` permanently removes an entire Vercel project. These tools ensure your agent can handle both initial setup and necessary cleanup steps within a single chain.

Setup guide

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