How to Use the Arcsecond.io MCP in Google ADK

Q: Can I filter which Arcsecond.io tools my Google ADK agent sees?

Yes, use the toolnames filter in your McpToolset definition. This restricts the agent to only the tools you want to expose.

Connect Arcsecond.io to Google ADK to process massive astronomical datasets within your Gemini enterprise workflows.

Query Arcsecond.io datasets via Google ADK

Connect `list_datasets` to your Gemini agent to see what observatory data is sitting ready for analysis. It pulls the list directly into your agent's memory. This works natively with your existing `McpToolset`. The agent parses the output and decides which dataset is relevant to the current task.

Manage observation logs with Google ADK

Use `list_night_logs` to bring historical observation data into your context. Gemini models handle the long-context needs easily. Your agent can now compare night logs across different sites. It builds a clear picture of what happened, allowing for better planning.

Identify astronomical objects using Google ADK

Run `search_objects` to query the Arcsecond.io database for specific coordinates or names. The tool returns data that your agent can immediately cross-reference. This keeps your agent focused on the task at hand. It avoids the need for manual data scraping or custom API wrappers.

Setup guide

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