Index CloudTalk data in LlamaIndex

Convert `list_contacts` and `list_calls` results into vector embeddings. You can then query your entire customer history using natural language instead of writing specific API filters. This creates a grounded knowledge base for your RAG application. Your agent answers questions based on real-time call logs rather than static documents.

Query past interactions with LlamaIndex

Reference previous `get_contact` outputs to retrieve specific conversation details. Your agent retrieves the context it needs to provide accurate, data-backed responses to your users. It solves the problem of stale data. Your index stays current because the agent pulls the latest records directly from the source.

Build RAG pipelines with CloudTalk

Use `McpToolSpec` to bridge your API data and your index. You decide which data to pull and how to format it for your vector store. This setup allows for deep semantic search across your entire support database. Your agent finds relevant call patterns that are otherwise buried in raw text.

Setup guide

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

Common questions about CloudTalk MCP in LlamaIndex

Use the BasicMCPClient to connect your endpoint and convert tools into a format LlamaIndex understands. This lets your agent interact with the phone system as a knowledge source.

Yes, by indexing the tool outputs into a vector store. You can then perform semantic searches to find specific calls or contact details.

No, because the agent relies on the retrieved API data to answer. The index provides the grounding necessary to keep responses accurate.

Yes, you can filter contacts or calls before they enter your index. It keeps your vector store clean and relevant.

Your contact names and phone numbers are handled within a secure Vinkius sandbox. Only the indexed vectors exist in your local store, protecting the raw data.
