How to Use the Mainstay (AdmitHub) MCP in LlamaIndex

Q: How does LlamaIndex handle large message logs from Mainstay (AdmitHub)?

The framework chunks the text returned by listmessages before embedding it. This ensures your vector store holds clean, searchable segments of student conversations.

Q: Can I filter Mainstay (AdmitHub) student profiles in LlamaIndex using custom fields?

Yes, your agent uses listcustomfields to identify available metadata. It then applies these fields as metadata filters during vector index retrievals.

Perplexity

Index active campaigns for semantic search

`list_campaigns` retrieves active outreach programs so LlamaIndex can index their goals and timelines into your document store. Your agent queries this index to find which campaigns match a student's current academic status. This setup connects raw campaign structures with your broader knowledge base. Instead of hardcoding rules, the agent performs semantic search over past campaigns to determine the best communication strategy.

Build RAG pipelines from student message logs

`list_messages` extracts the full history of student SMS exchanges to populate your local vector index. LlamaIndex uses these logs to provide context-rich answers about a student's past hurdles or complaints. Your query engine searches these historical text blocks to identify recurring friction points. This keeps your agent's responses grounded in actual conversation history, preventing hallucinations during student support sessions.

Query custom fields via the LlamaIndex MCP Server

`list_custom_fields` defines the schema of your student database, allowing LlamaIndex to structure its queries accurately. The agent reads these definitions to understand what metadata is available before pulling records. By combining this with `get_contact_details`, your index stays updated with the latest enrollment variables. Your agent queries this structured data to filter search results based on specific student attributes.

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Mainstay (AdmitHub) MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Mainstay (AdmitHub) tools.",
)
response = await agent.run("List recent Mainstay (AdmitHub) data")
