How to Use the Apptoto MCP in LlamaIndex

Q: How do I load Apptoto MCP tools into LlamaIndex?

Run pip install llama-index-tools-mcp in your environment. Create a BasicMCPClient with your Vinkius URL, then wrap it in McpToolSpec. Call await mcptoolspec.totoollistasync() to get your functions.

Q: Can I restrict which tools the indexer uses?

The allowedtools filter lets you limit access. You pass an array of specific function names like listcalendars if you only want schedule data indexed.

Q: How do I query specific client confirmations in LlamaIndex?

Set includeresources=True when configuring your MCP tool spec to allow direct data access. The query engine then searches the indexed message logs for specific confirmation keywords.

Index Apptoto appointment histories directly via this MCP Server into LlamaIndex to build context-aware scheduling assistants.

Grounding RAG with Apptoto MCP Server

Apptoto provides the `list_appointments` and `get_appointment` tools to pull live booking data into your LlamaIndex pipeline. Instead of just reading the schedule, your agent converts these records into searchable vector embeddings. Querying past sessions becomes a simple semantic search operation. Your application retrieves exact meeting times and confirmation statuses rather than hallucinating dates.

Indexing Contacts and Address Books

The `list_address_books` and `list_contacts` tools extract your entire client directory. Your indexer ingests these names and phone numbers alongside your internal company documents. Combining live API data with static PDFs creates a unified knowledge base. A user asks about a specific client, and the engine pulls their exact contact record from the index.

Querying Message Histories

Pulling recent SMS replies requires calling the `list_messages` tool. This function feeds raw communication logs straight into your document store. Building an agent with `FunctionAgent` lets it search this specific message index. The system checks if a client confirmed their booking before taking further action.

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")

Common questions about Apptoto MCP in LlamaIndex

Run `pip install llama-index-tools-mcp` in your environment. Create a `BasicMCPClient` with your Vinkius URL, then wrap it in `McpToolSpec`. Call `await mcp_tool_spec.to_tool_list_async()` to get your functions.

The `allowed_tools` filter lets you limit access. You pass an array of specific function names like `list_calendars` if you only want schedule data indexed.

The vector store retains the embeddings based on your specific database configuration. You decide whether to persist the MCP index to disk or keep it entirely in memory.

Set `include_resources=True` when configuring your MCP tool spec to allow direct data access. The query engine then searches the indexed message logs for specific confirmation keywords.

SMS and email histories from your bookings only exist within the zero-trust execution environment. The host system uses ephemeral tokens that expire instantly. Your raw message text never touches persistent storage on our end.
