Live news ingestion for Google ADK

The `get_news` tool fetches live articles for your Gemini-powered agents. It works with long-context windows to provide deep analysis of current events. You can feed this data into BigQuery or other Google Cloud services your agent already manages. It bridges the gap between raw news and your internal infrastructure.

Publisher inventory for Google ADK

Call `list_sources` to retrieve the full catalog of supported news outlets. Your agent uses this to maintain a precise list of where it pulls its information. This visibility helps your agents maintain data integrity when reporting on global events. You stay in control of the information pipeline at all times.

Native transport for Google ADK

The server connects via the `McpToolset` class in the Google ADK. It supports both Stdio and HTTP, fitting right into your existing cloud deployment. You can restrict tool access by using a tool name filter. This keeps your agent's environment locked down while providing access to the news data it needs.

Setup guide

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