Prevent generic layouts in Google ADK enterprise agents

Enterprise frontends built with Gemini models often default to safe, boring card grids. This MCP Server injects a hard stop by requiring the agent to call `prove_design` and prove its layout does not look like a generic template. The tool forces your agent to justify its visual choices, including asymmetric columns and dramatic whitespace. It integrates directly into your Google ADK toolset, keeping your enterprise apps looking custom and professional.

Analyze complex layout schemas with long-context reasoning

Gemini's massive context window lets your agent analyze entire design systems at once. When the agent uses `prove_design`, it can compare its proposed UI against your company's design rules stored in Google Cloud. The tool ensures that even with massive inputs, the agent maintains strict typographic ratios and bold color choices. Your agent will not slip back into lazy design habits over long conversational runs.

Connect design validation to your BigQuery data pipelines

You can feed user engagement metrics from BigQuery directly into your agent's design loop. The agent runs the `prove_design` tool to check layouts against successful design patterns stored in your warehouse. This setup lets your agent generate high-converting, custom layouts on the fly. Our validation tool acts as the final gatekeeper, ensuring every generated interface meets your strict aesthetic standards.

Setup guide

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

Common questions about Design Prover MCP in Google ADK

Install the SDK, create an McpToolset pointing to your Vinkius HTTP MCP Server URL, and pass it to your LlmAgent tools list. The agent will auto-discover the validation capabilities.

Yes, you can use the tool name filter in your toolset configuration. This allows you to expose the `prove_design` tool only to your dedicated frontend generation agents.

The tool processes the specific layout constraints and typographic ratios extracted from the context. It quickly returns a pass or fail status, keeping your agent's reasoning loop fast and focused.

No, the server runs in a secure sandbox on Vinkius. You only need to pass the connection URL to your Google ADK toolset, with no extra cloud infrastructure to manage.

Only raw layout structures, font sizes, and color palettes are sent to the tool for validation. No user data, BigQuery tables, or internal cloud credentials are ever exposed to the external MCP Server.
