How to Use the TeleSign MCP in LlamaIndex

Q: Can I track phone numbers using LlamaIndex and TeleSign?

Yes. You can index all historical results from getphoneid and scorephone. This lets you build a knowledge graph of the number's activity over time.

Q: Does LlamaIndex support multi-stage verification with TeleSign?

It does. You can index both successful sendpushverification attempts and failures, allowing you to build a comprehensive record of the full user journey for auditing.

Q: Can I use LlamaIndex to validate API connectivity with TeleSign?

Yes, you can index the output of checktelesignstatus. This allows users to query historical uptime records and know exactly when an API connection was verified.

Building Searchable Verification Knowledge with LlamaIndex

The output of any tool call becomes part of your indexed knowledge base. For example, when you run `score_phone`, the returned risk score is stored alongside the timestamp and the phone number used. Later, a user can query historical data like: 'What was the risk score for this number last month?'—and LlamaIndex answers using that saved API result.

Tracking Phone Number History via MCP Server

You build RAG applications that track phone usage over time. You can index every call to `get_phone_id` and `get_phone_type`. This allows you to query past configurations or suspicious patterns from previous sessions. The system keeps a searchable record of whether an SMS was sent using `send_sms` or if a voice verification using `send_voice_verification` was used previously.

Querying Verification Status and Rules

LlamaIndex lets you query the results from management tools. You can index all `check_verification` outcomes, so your knowledge base answers questions like: 'Why did this verification fail last week?' This is crucial for auditing; it grounds complex API data—like deactivation status from `check_deactivation`—into plain, searchable text.

Setup guide

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