How to Use the CallGear MCP in Google ADK

Q: How do I initialize the CallGear MCP Server in Google ADK?

Use McpToolset with StreamableHttpServerParameters pointing to your Vinkius URL. Then, pass this toolset into the tools list when creating your LlmAgent.

Q: Can I restrict Google ADK to only use specific CallGear MCP tools?

Yes, use the optional toolnames filter when instantiating your McpToolset. This prevents the agent from seeing or invoking tools like listusers if they aren't needed.

Connect CallGear data to Gemini's 1M token context using the Google ADK.

Feed Call Reports to Google ADK and BigQuery

The `get_calls_report` tool pulls detailed call logs directly into your Google ADK environment for large-scale analysis. Because Gemini models handle massive context windows, your agent can ingest thousands of call records at once to spot macro-level communication trends. You pass the toolset to your `LlmAgent` using the HTTP transport parameters. Once the agent retrieves the data, you can pipe the raw telemetry straight into BigQuery for persistent storage and SQL analysis.

Analyze Ad Channels with this MCP Server

The `get_ad_campaigns_report` tool retrieves daily aggregated ad spend and conversion metrics directly inside your Gemini agent workflow. This MCP Server allows your Google ADK agent to evaluate which marketing efforts drive actual phone inquiries. Using `list_traffic_sources` alongside this report lets your agent build attribution models. You can restrict the agent's scope by passing a specific list of tools to the `tool_names` filter during initialization.

Inspect Agent Performance and Site Daily Stats

The `get_site_daily_stats` tool exposes web traffic metrics to your Google ADK agent, allowing it to correlate online visits with offline calls. Your agent can query `list_users` to see which team members handled the resulting inbound communication. This setup uses the `McpToolset` class to register the CallGear endpoints. The agent executes these queries locally or in your Google Cloud environment, keeping your operational data inside your secure cloud perimeter.

Setup guide

Set up CallGear 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 CallGear 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="CallGear_agent",
    model="gemini-2.0-flash",
    instruction="You have access to CallGear tools via MCP.",
    tools=mcp_tools,
)
