How to Use the Apptoto MCP in LlamaIndex

Q: How can I use LlamaIndex to find a specific Apptoto contact?

Let your agent index your contacts using listcontacts. After that, you can ask questions like 'find the phone number for John Smith' and LlamaIndex will query its index to get the answer.

Q: Can LlamaIndex summarize my upcoming Apptoto appointments?

Yes. Configure a FunctionAgent to use the listevents tool. It can fetch your upcoming appointments for the week and then generate a summary for you based on that data.

Q: What's required to connect LlamaIndex to my Apptoto account?

Install the llama-index-tools-mcp package and initialize the BasicMCPClient with your Vinkius endpoint URL. LlamaIndex handles the tool definitions from there.

Q: Can I filter which Apptoto tools my agent can use?

Yes. The McpToolSpec supports an allowedtools filter. You can give an agent access to only listevents and getevent if you want to create a read-only scheduling assistant.

Turn your Apptoto schedule into a searchable knowledge base with LlamaIndex. Query your appointments and contacts using natural language.

Index Your Apptoto Activity

Your LlamaIndex agent doesn't just call an Apptoto tool once. It can run `list_events` and `list_bookings` and then index the results into a vector store. Your schedule and client history become a queryable knowledge base. Now you can ask questions about past activity. Your agent can answer 'What was that meeting about last week?' by searching the indexed data from previous `get_event` calls, grounding its response in actual calendar data.

Build a RAG Agent for Your Schedule

Combine live Apptoto data with your own documents. Your agent can cross-reference meeting notes from a local file with actual appointment data pulled via the `get_event` tool. The answers it gives are based on both sources. This is how you build a true assistant. It can answer 'Summarize my meetings with Acme Corp' by finding the appointments with `list_events` and then pulling context from your indexed notes. This MCP Server provides the live data for that process.

Query Apptoto Data with LlamaIndex

Forget figuring out the right API call. Just ask a question. LlamaIndex can translate 'Show me my contacts in the new client list' into a call to `list_lists` and then `get_contact` for each person on it. You're interacting with your Apptoto account through semantic search. The agent understands your intent and uses the available tools to find the answer, even if it requires multiple steps.

Setup guide

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