Perplexity

Chain school data into reasoning pipelines

Pipe the output of `search_colleges` directly into `get_college_details` to build autonomous research flows. Your agent decides the next step based on the data it just pulled, creating a logical chain of inquiry. Everything happens inside your LangSmith traces. You see exactly how the agent navigated the API responses to reach its conclusion.

Filter programs with LangChain logic

Feed `get_fields_of_study` into your chain to extract specific academic data points. You control the flow of information between this MCP server and your local databases. Use your agent to compare costs across different institutions. It links the tools in the order you define, ensuring the data stays consistent throughout the execution.

Geographic analysis with LangChain tools

Use `list_colleges_by_zip` or `list_colleges_by_city` as the starting point for your chain. Your agent identifies relevant schools before pulling deeper academic profiles. This MCP server gives your LangChain agent direct access to structured school data. It turns your agent into a research machine that handles complex queries without manual intervention.

Setup guide

Set up College Scorecard API 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 College Scorecard API 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({
    "college-scorecard-api-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 College Scorecard API transactions"
    })
    print(result["messages"][-1].content)

Common questions about College Scorecard API MCP in LangChain

Install the MCP adapters and point your client to the server URL. You then pass the tool list into your agent constructor to enable direct access.

Absolutely. You can aggregate multiple server tools and let the agent select which ones to call based on the user prompt.

It is stateless by default. Use the client session object if you need to maintain context across multiple turns.

We only touch public US Department of Education school data. No user-specific PII or private institutional records are transmitted through this connection.

The server returns standard tool outputs that your agent interprets as text. You can add error handling logic within your LangChain chain to retry failed requests.
