How to Use the Builder.io (Visual CMS) MCP in Google ADK

Q: How do I register the Builder.io (Visual CMS) MCP Server within the Google ADK?

Use the McpToolset class with your Vinkius HTTP endpoint. Pass this toolset directly into the tools parameter of your LlmAgent initialization.

Q: Can I use Google ADK to filter specific Builder.io (Visual CMS) tools?

Yes, you can specify an optional toolnames array in your StreamableHttpServerParameters. This limits the agent to only the tools you want it to use, like restricting it to getcontent.

Q: How does this server handle large media files?

The uploadasset tool handles files by taking a direct URL or binary stream. The server processes the upload and returns the Builder.io CDN link for your agent to use.

Connect Gemini models to your Builder.io (Visual CMS) using the Google ADK to analyze and edit layout data at scale.

Perplexity

Feed visual CMS schemas into Google ADK

`query_graphql` lets your Gemini models analyze massive amounts of CMS layout data at once using this MCP Server. Because the Google ADK integrates with high-capacity context windows, you can pass entire schemas and content models directly to the agent. The agent processes your Builder.io structure alongside corporate data from BigQuery. This allows the model to make informed decisions about what content to update.

Bulk content edits and asset uploads

`create_content` and `upload_asset` tools let your Google Cloud agents build new pages programmatically. The agent uploads media files and structures new document entries without manual intervention. You can restrict which tools are exposed by passing a `tool_names` filter to your `McpToolset` configuration. This keeps your production environment safe from unauthorized modifications.

Direct HTML inspection for layout control

`get_html` fetches the raw pre-rendered code of your visual components. Your Gemini agent reads this markup to understand the exact structure of your web pages. If a layout looks broken, the agent can run `update_content` to fix the underlying JSON. This closes the loop between layout analysis and content generation.

Setup guide

Set up Builder.io (Visual CMS) 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 Builder.io (Visual CMS) 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="Builder.io (Visual CMS)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Builder.io (Visual CMS) tools via MCP.",
    tools=mcp_tools,
)
