Deterministic date math for Gemini pipelines
The `calculate_legal_deadline` tool integrates into Google ADK to stop Gemini models from hallucinating court dates during long-context document analysis. While Gemini excels at scanning 1M+ tokens of legal files to find trigger events, it cannot reliably calculate business days. This tool handles the calendar math deterministically. Look, the fact is, relying on generative models for statutory math leads to malpractice. By exposing this tool to your `LlmAgent`, you ensure that the extracted trigger date is passed to a rigid, rule-based calculator.
Connect BigQuery docket data to the MCP server
The `calculate_legal_deadline` tool operates alongside your existing Google Cloud infrastructure. Your Google ADK agents can pull raw docket tables from BigQuery, identify the filing trigger dates, and pipe them directly into the calculator. This setup bridges the gap between structured enterprise databases and deterministic court rules. The agent handles the data coordination, while the MCP server guarantees that the holiday and weekend rollovers are mathematically perfect.
Native toolset registration with Google ADK
You register the `calculate_legal_deadline` tool by passing `McpToolset` to your agent's tools parameter. The SDK auto-discovers the schema, allowing Gemini to call the MCP Server natively during reasoning loops. You can restrict the agent's tool access using the `tool_names` filter. This ensures your legal agent only executes the deadline calculator and does not wander into unapproved operations.
Set up Legal Deadline Calculator Engine MCP in Google ADK
Prerequisites
- Python 3.10+ installed
-
google-adkpackage (pip install google-adk) - Active Vinkius subscription with a valid endpoint token
- 1
Install Google ADK
Run
pip install google-adkto install the Agent Development Kit. MCP support is included via theMcpToolsetclass. - 2
Connect via SSE transport
Use
McpToolset.from_server()withSseServerParamspointing to your Vinkius endpoint. Replace[YOUR_TOKEN_HERE]with your token from cloud.vinkius.com. - 3
Create an LlmAgent
Pass the returned
mcp_toolslist directly toLlmAgent(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 Legal Deadline Calculator Engine tools in your ADK agent.
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(
