How to Use the Hostelworld MCP in LlamaIndex

Q: How does LlamaIndex store data retrieved from Hostelworld?

LlamaIndex converts the JSON output from getpropertydetails into document nodes. These nodes are stored in your selected vector database, making the hostel's amenities and policies searchable via semantic queries.

Q: Can I filter Hostelworld properties before indexing them in LlamaIndex?

Yes, you can use the listcityproperties tool to pull listings, then apply LlamaIndex node post-processors to filter by rating or price. This ensures only highly-rated hostels enter your index.

Q: How does LlamaIndex handle live price updates from the Hostelworld MCP server?

Your agent calls getpropertyavailability dynamically during the query phase rather than relying on static index data. This guarantees that the room prices shown in the final response are accurate for those specific dates.

Q: Can I build a RAG pipeline using hostel images retrieved via MCP?

Yes, by using getpropertyimages alongside your index, LlamaIndex can retrieve image URLs for matching properties. Your agent then serves these image links directly to the user to visually confirm the hostel quality.

Indexing Live Hostelworld Listings

The `list_city_properties` tool retrieves a raw list of hostels for any specified city ID to build your local LlamaIndex knowledge index of Hostelworld options. LlamaIndex takes this structured Hostelworld property data and converts it into document nodes for semantic search. Instead of guessing what hostels are available, your LlamaIndex agent queries this indexed Hostelworld MCP data to find budget stays. This prevents the LlamaIndex model from hallucinating Hostelworld names or prices, grounding every recommendation in actual API data.

Semantic Search on Guest Reviews

The `get_property_reviews` MCP tool extracts raw guest feedback from the Hostelworld profile page directly into your LlamaIndex pipeline. LlamaIndex indexes these Hostelworld reviews so your agent can search for specific vibes, like quiet study spaces or social party atmospheres in hostels. This turns unstructured Hostelworld text into searchable LlamaIndex vectors for quick travel matching. When a traveler asks for a social hostel, the LlamaIndex framework matches their query against actual Hostelworld review text rather than relying on generic tags.

Real-Time Availability Checks with LlamaIndex

The `get_property_availability` tool checks live room pricing and open dates for any specific Hostelworld property ID within LlamaIndex. LlamaIndex uses this tool to inject real-time Hostelworld context directly into your query pipeline right before generating a response. You can filter these queries using `search_properties` to narrow down the list of Hostelworld properties before LlamaIndex checks dates. This keeps your LlamaIndex vector store updated with the latest Hostelworld rates, ensuring your agent never recommends a booked-out dorm.

Setup guide

Set up Hostelworld MCP in LlamaIndex

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 Hostelworld 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 Hostelworld tools.",
)
response = await agent.run("List recent Hostelworld data")
