How to Use the Circadian REM Sleep Cycle Optimizer MCP in Google ADK

Q: How do I integrate the Circadian REM Sleep Cycle Optimizer with a Gemini agent using the Google ADK?

You'll use the McpToolset from the Google ADK library, pointing it to the Vinkius server URL. Then you just pass that toolset to your LlmAgent constructor. The agent will automatically discover the available sleep tools.

Q: Is it possible to filter which tools the Google ADK exposes from the Circadian REM Sleep Cycle Optimizer?

Yes. When you configure the McpToolset, you can provide an optional toolnames list. This restricts your agent to using only the specific sleep-calculation tools you authorize.

Perplexity

Plan Team Schedules Around Peak Energy

The `calculate_circadian_rhythm` tool maps daily energy cycles from a single wake-up time. Your Gemini agent can use this to build smarter scheduling systems for your team, suggesting meeting times that align with collective energy peaks. Since the Google ADK integrates natively with Google Cloud, your agent could pull wake-up times from a team roster in BigQuery, run them through this tool, and find the best slots for collaborative work. It's a practical way to reduce meeting fatigue.

Calculate Sleep Schedules for On-Call Rotations

Use the `calculate_sleep_cycles` tool to determine optimal bedtimes and wake-up times based on 90-minute REM phases. This is critical for roles that demand high alertness, like on-call engineering shifts or logistics operations. A Gemini agent built with the Google ADK can automate this. It can check an on-call schedule in Google Calendar, use this tool to calculate the ideal bedtime for the person on duty, and send them a notification. This MCP Server provides the logic; the ADK connects it to your infrastructure.

Analyze Sleep Debt Trends with this MCP Server

The `calculate_sleep_debt` tool takes a list of hours slept and calculates the cumulative deficit and a recovery plan. It turns raw sleep data into an actionable health metric. Here's where the Google ADK shines. Your agent can pull months of employee sleep data from BigQuery, run it through this tool in batches, and then use Vertex AI to analyze long-term trends in sleep debt across departments. You can spot burnout risks before they become problems.

Setup guide

Set up Circadian REM Sleep Cycle Optimizer 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 Circadian REM Sleep Cycle Optimizer 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="Circadian REM Sleep Cycle Optimizer_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Circadian REM Sleep Cycle Optimizer tools via MCP.",
    tools=mcp_tools,
)

Common questions about Circadian REM Sleep Cycle Optimizer MCP in Google ADK

You'll use the `McpToolset` from the Google ADK library, pointing it to the Vinkius server URL. Then you just pass that toolset to your `LlmAgent` constructor. The agent will automatically discover the available sleep tools.

Absolutely. A common pattern is to have your Gemini agent query sleep logs from a BigQuery table, then pass that data directly to a tool like `calculate_sleep_debt` from this MCP Server.

Yes. When you configure the `McpToolset`, you can provide an optional `tool_names` list. This restricts your agent to using only the specific sleep-calculation tools you authorize.

Vinkius manages the server for you. That means you don't have to worry about hosting, dependencies, security, or uptime. You just get a reliable endpoint that your agent can call.

Yes. The server only sees the necessary inputs for a calculation, like wake-up times and hours slept. Each tool call runs in a dedicated, single-use sandbox that is immediately torn down. The Google ADK communicates with this MCP server over a secure, authenticated channel.
