How to Use the Checkfront MCP in LlamaIndex

Q: Can LlamaIndex filter which Checkfront tools the agent sees?

You can restrict access using the allowedtools filter. This lets you build a public-facing bot that only sees checkavailability and listcategories, keeping internal tools hidden.

Index Checkfront tour data directly into LlamaIndex to build RAG applications grounded in live bookings and rental inventory.

Index Live Checkfront MCP Server Data

When your agent calls `list_items`, LlamaIndex transforms the raw API response into searchable vectors. It ingests the entire catalog of bookable tours into a local knowledge base. The system skips simple text reading and stores the mathematical relationships. This means subsequent queries hit the vector store first. Users ask about specific tour policies, and the system retrieves the exact rental rules pulled from `get_item`. You get semantic search across your entire live inventory.

Query Bookings with RAG

A LlamaIndex RAG pipeline runs `list_bookings` to pull Saturday's tour schedule and embeds that data alongside your internal company documents. Traditional agents guess at schedules, but this setup grounds the answers in reality. When staff ask who is scheduled for the morning kayak trip, the FunctionAgent fetches the exact reservation details via `get_booking`. The final answer combines your static SOPs with real-time reservation facts, eliminating hallucinations.

Embed Customer Histories

You configure the agent to execute `search_customers` and index the resulting contact info, total spend, and waiver status for fast support context. Support teams get a unified query interface. Your RAG application now understands customer value. If a high-spend client emails about a refund, the system cross-references their profile with your cancellation policy documents. It drafts a response grounded in actual account data from `get_account`.

Setup guide

Set up Checkfront 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 Checkfront 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 Checkfront tools.",
)
response = await agent.run("List recent Checkfront data")

Common questions about Checkfront MCP in LlamaIndex

Run pip install llama-index-tools-mcp. Create a BasicMCPClient pointing to your Vinkius endpoint, wrap it in McpToolSpec, and await to_tool_list_async() to feed the tools to your agent.

You can restrict access using the allowed_tools filter. This lets you build a public-facing bot that only sees check_availability and list_categories, keeping internal tools hidden.

It stores the vector embeddings in whichever database you configure. The actual API calls to get_booking happen in real-time to keep the index fresh.

Semantic search makes the difference. LlamaIndex blends live Checkfront data with your static PDF guides, allowing users to query both systems simultaneously.

Vinkius enforces a zero-trust architecture. When your agent fetches waiver statuses or contact details, the data passes through an ephemeral sandbox requiring a single endpoint token, ensuring no standing access remains.
