How to Use the TeleSign MCP in Google ADK

Q: Can TeleSign provide phone details for Google ADK?

Yes, the server offers getphoneid, which fetches core identity information. It also provides getphonetype to categorize the number, giving your agents deeper data points for analysis.

Q: What if my agent needs to check basic connectivity with TeleSign and Google ADK?

Check API health first using checktelesignstatus. This tool confirms that the entire communication channel is working before your enterprise workflow attempts any resource-intensive operations like sending an SMS.

Q: How does TeleSign handle failed verification steps with Google ADK?

The MCP Server allows for sequential calls. If sendpushverification fails, the agent can immediately call sendsms. This retry logic ensures a complete user flow without requiring manual intervention.

Score Phone Risk for BigQuery Analysis

Use `score_phone` to generate a risk score, which you can then pipe directly into your BigQuery tables. This lets your agents run advanced queries on phone intelligence alongside other enterprise data. The resulting fraud scores help refine internal models. You can correlate the output of `get_phone_id` with historical user behavior already stored in Vertex AI.

Verify Identity and Track Status

The core identity check happens when you call `check_verification`. This tool provides a definitive status that can be written back into your Google Cloud records. You also need to track the source data. Tools like `get_phone_type` tell you if the number is mobile or landline, adding context to records stored in BigQuery.

Orchestrate Multi-Step Verification Workflows

To maximize security, your agent can sequence multiple checks. For instance, it might start with `send_push_verification`, and if that fails, fall back to a code sent via `send_sms`. The MCP Server handles the logic for this handover. If all digital methods fail, you can escalate by calling `send_voice_verification` to capture an audio layer of verification.

Setup guide

Set up TeleSign MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with TeleSign tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="TeleSign_agent",
    model="gemini-2.0-flash",
    instruction="You have access to TeleSign tools via MCP.",
    tools=mcp_tools,
)
