Chain An API of Ice And Fire tools in LangChain

Feed the output of `get_character` directly into your next chain link. You aren't just fetching data; you're building logic flows where your agent decides which house or book to query next. LangSmith captures every step of this process. You'll see exactly how your agent navigates the series data with full visibility into latency and token consumption.

Automate multi-step research with your MCP Server

Trigger `list_books` to populate a context window for your agent. It parses the results to determine the exact `get_book` calls needed to fill in missing plot details. This MCP Server acts as a reliable data source for your agent's reasoning. You get cleaner output by letting the framework manage the tool selection logic.

Aggregate data across the Seven Kingdoms

Combine `list_houses` with your existing SQL or vector store integrations. LangChain treats these tools as native nodes in your graph. Your agent cross-references external databases with the Ice and Fire records in one pass. It's a faster way to build systems that rely on real-time API lookups.

Setup guide

Set up An API of Ice And Fire 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 An API of Ice And Fire 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({
    "an-api-of-ice-and-fire-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 An API of Ice And Fire transactions"
    })
    print(result["messages"][-1].content)

Common questions about An API of Ice And Fire MCP in LangChain

Install the langchain-mcp-adapters package to bridge the connection. You'll pass the server URL to the client, then inject the tools into your agent definition.

Yes, by chaining multiple calls together. An agent can list characters, filter by culture, and then pull specific house details based on the results.

Absolutely. Every interaction shows up in LangSmith as a standard tool call, letting you monitor the exact inputs and outputs processed by the server.

It is stateless by default, which works for most single-request tasks. Use the client session if you need to maintain context across a long-running chain.

The server only handles public book, character, and house data from the series. No private user information is ever requested or stored during these lookups.
