Grounding Agents in Enterprise Data

The `validate_yakunashi` tool prevents your agent from making assumptions when querying vast datasets. It forces the agent to explicitly list all required facts before generating an answer. This means agents acting on BigQuery data can't proceed if they haven't scoped their query against every necessary dimension.

Detecting Data Sufficiency Gaps

It checks if the information available in your long-context memory is sufficient for a confident answer. If it detects gaps—for example, missing metadata fields—it triggers safe folding. This prevents mission failure caused by operating on incomplete or partially scoped data sets.

Enforcing Epistemic Calibration

The MCP Server calibrates your agent's confidence level based only on the evidence it finds. It won't let Gemini model output a high certainty score if the underlying data sources are thin. This is crucial for maintaining accuracy when dealing with 1M+ token contexts.

Setup guide

Set up Yakunashi-Safety Gate 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 Yakunashi-Safety Gate 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="Yakunashi-Safety Gate_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Yakunashi-Safety Gate tools via MCP.",
    tools=mcp_tools,
)

Common questions about Yakunashi-Safety Gate MCP in Google ADK

It adds a critical layer of pre-execution validation to your Gemini agents. Before the agent uses data from BigQuery, it must confirm all preconditions are met.

Use this MCP Server whenever an agent's answer needs to be traceable back to specific facts in your enterprise data. It prevents vague, high-confidence summaries.

Yes. The tool is specifically designed to detect speculation (yakunashi). If the agent tries to invent a metric or fact not present in the context, it halts execution.

It processes structured and unstructured inputs from your environment, especially payloads originating from BigQuery or other Google Cloud sources.

You pass it as a toolset when configuring your LlmAgent. This makes its safety checks part of your standard agent workflow, ensuring every query is audited.
