How to Use the Viesus MCP in LangChain

Q: How do I check Viesus API credits using LangChain?

You use the getaccountcreditbalance tool. This tells your agent exactly how many API credits are left before it attempts a major job. It keeps the whole process running smoothly.

Q: Does Viesus support multiple image formats with LangChain?

The listsupportedfileformats tool tells your agent exactly which types of images are accepted. This validation step prevents the client from uploading a bad file type, saving time and credits.

Q: What metadata can I get for an image with Viesus using LangChain?

After processing, you use getimagemetadata to pull technical details about the original or enhanced picture. This gives context beyond just the final download link.

Q: What is the best way to validate Viesus uptime with LangChain?

You run the checkapihealth tool at the beginning of your chain. It's a simple, direct call that confirms the entire Viesus MCP Server stack is operational before proceeding.

Workflow Management

The `list_enhancement_presets` tool lets your agent check available AI styles before any processing starts. Then, the `upload_image_to_viesus` tool handles getting the image into the system. The LangChain framework excels at chaining these calls together. You can build a multi-step pipeline: first listing presets, then uploading an image, and finally checking job status with `get_enhancement_job_status`. It's all one coherent flow.

API Status Checks

Need to know if Viesus is up before starting a big job? Use the `check_api_health` tool first. This quick check validates the entire process, telling you immediately if the service is ready. Your agent can also verify resources by calling `get_account_credit_balance`. It's smart to check credits and API version details (`get_api_version_info`) early on. The LangChain client handles these sequential checks cleanly.

Job Lifecycle Tracking

When you upload a file, the enhancement happens asynchronously. Use `get_enhancement_job_status` to track progress and wait for completion. Once it's done, call `get_enhanced_image_url` to grab the final download link. This pattern—uploading, waiting, then downloading—is perfect for complex chains. The agent manages this state change using sequential tool calls.

Setup guide

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