How to Use the GenerateBanners MCP in LangChain

Q: How do I connect GenerateBanners to LangChain?

Install the langchain-mcp-adapters package. Initialize MultiServerMCPClient with the server URL and pass the loaded tools to your agent.

Q: Can LangChain agents pick the right GenerateBanners template automatically?

Yes. Your agent calls searchtemplates with your design criteria. It evaluates the returned metadata and selects the best layout for your copy.

Q: What happens if the GenerateBanners MCP connection drops during a LangChain run?

You can build a fallback step using checkgbstatus. If the tool returns an error, LangChain aborts the chain before wasting tokens on failed renders.

Chain template discovery in LangChain

The `search_templates` tool lets your agent find specific brand layouts based on user prompts. LangChain evaluates the output and decides if it needs to narrow the results using `list_categories` before moving to the next step. LangSmith gives you full observability when your agent calls `get_template` to inspect the required text fields. The agent parses the schema and automatically maps your database content to the template variables.

Automate campaign project structures

The `create_project` tool lets your ReAct agent spin up isolated workspaces for new ad campaigns. If a campaign finishes, the agent can trigger `delete_project` as part of a teardown chain to keep your dashboard clean. Your agent uses `list_projects` and `get_project` to check existing campaign metadata before creating duplicates. LangChain tracks the token usage for these API calls while maintaining context across the session.

Batch render graphics via this MCP Server

The `render_batch` tool chews through hundreds of banner variations in a single chain execution. Your agent pulls ad copy from a vector store, formats the data, and fires the batch request to the server. For one-off requests, the agent calls `render_template` and returns the direct image URL to the user. You can monitor the API health mid-chain using `check_gb_status` to prevent failed render attempts.

Setup guide

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

Common questions about GenerateBanners MCP in LangChain

Install the `langchain-mcp-adapters` package. Initialize `MultiServerMCPClient` with the server URL and pass the loaded tools to your agent.

Yes. Your agent calls `search_templates` with your design criteria. It evaluates the returned metadata and selects the best layout for your copy.

Your chain formats an array of text variations and passes them to `render_batch`. The server processes the queue and returns a list of image URLs.

You can build a fallback step using `check_gb_status`. If the tool returns an error, LangChain aborts the chain before wasting tokens on failed renders.

The server processes your raw text strings and image URLs during rendering. Vinkius runs this node in a V8 Isolate Sandbox, destroying the memory context immediately after the image generates.
