Build Multi-Step Baking Pipelines

Your agent can run a full baking assessment in one chain. Start by calling `calculate_hydration` to determine if your mix is too wet or dry, then pass that resulting percentage into the next step. This chaining ability means you don't just get an answer; you build a verifiable process. You use the output of calculating hydration percentage as the direct input for classifying the expected texture.

Validate Dough Suitability

Need to know if your ingredients even work together? The system uses `determine_dough_type` based on flour and salt composition. This initial check helps you narrow down whether you're making bread, pizza, or focaccia before any complex calculations. It’s a crucial first step in a workflow. You can link this tool call to others, ensuring the entire pipeline operates only on inputs that make sense for your baking goal.

Assess Dough Structure and Texture

After you know the hydration level, `classify_texture` takes over. It reads both the calculated percentage and the profile name to give a specific structural diagnosis—like 'open crumb' or 'dense.' This allows your LangChain agent to make decisions based on physical properties. The output isn't just text; it's actionable data that drives subsequent steps in the chain.

Setup guide

Set up Hydration Calculator 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 Hydration Calculator 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({
    "hydration-calculator-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 Hydration Calculator transactions"
    })
    print(result["messages"][-1].content)

Common questions about Hydration Calculator MCP in LangChain

The MCP allows your agent to treat baking science like any other API call. You can build chains that execute calculation, classification, and type determination sequentially, making the process transparent for tracing.

While the core focus is chaining, the structured outputs of this MCP provide clean inputs that can be easily passed to your vector store or database via subsequent nodes in the chain.

You feed it basic measurements like flour and liquid weights, as well as ingredient profiles such as flour and salt composition. These simple inputs drive complex baking predictions.

Absolutely. Because every tool call generates an auditable trace—from calculating hydration to classifying texture—you'll see exactly how your agent arrived at its final conclusion, making debugging straightforward.

The server handles quantitative measurements related to ingredient composition, specifically flour and salt composition, alongside weight metrics for liquid.
