How to Use the Campinas Open Data MCP in Google ADK

Q: How does Gemini's long context help when analyzing Campinas Open Data?

Gemini can ingest large CSV schemas returned by getpackage without hitting context limits, letting your agent write complex SQL queries for BigQuery based on the city's data structure.

Connect Gemini to Campinas Open Data using Google ADK for deep reasoning over Brazilian municipal datasets.

Query Campinas Open Data inside Google ADK

The `search_packages` and `search_resources` tools feed Campinas municipal data directly into your Google ADK agent. This lets Gemini parse complex city spreadsheets and cross-reference them with your existing BigQuery datasets. Because Gemini handles massive token contexts, you can feed entire resource lists returned by the MCP Server straight into your prompt. Our approach allows for deep analytical reasoning over years of Brazilian public records.

Inspect specific city resources and groups

The `get_resource` and `list_groups` tools allow your Google ADK agent to extract specific file schemas and thematic categories from the Campinas registry. Your enterprise agent uses these tools to map public health or education data before running analytical pipelines. You configure the McpToolset with your Vinkius HTTP transport URL. Gemini models handle the connection automatically, making these Brazilian public datasets instantly available inside Vertex AI.

Discover city agencies on the fly

The `list_organizations` and `list_tags` tools give your Google ADK agent the ability to map out which Campinas departments publish specific datasets. Calling these tools lets the agent organize raw data before saving it to Google Cloud Storage. This dynamic discovery means you don't need to maintain a local list of city departments. Your Gemini agent queries the live portal to find the correct publisher for any record.

Setup guide

Set up Campinas Open Data 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 Campinas Open Data 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="Campinas Open Data_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Campinas Open Data tools via MCP.",
    tools=mcp_tools,
)

Common questions about Campinas Open Data MCP in Google ADK

Instantiate the McpToolset class with your Vinkius streamable HTTP URL. Pass this toolset directly into your LlmAgent constructor to expose the city data tools.

Yes. You can pass a filtered list of tool names to the McpToolset constructor to ensure specific agents only access search tools like `search_packages`.

Yes. While Vinkius hosts the MCP Server over HTTP, Google ADK supports both transports, letting you run local tests or cloud deployments easily.

Gemini can ingest large CSV schemas returned by `get_package` without hitting context limits, letting your agent write complex SQL queries for BigQuery based on the city's data structure.

Your queries touch public Brazilian municipal records only. Vinkius secures the MCP transport layer, ensuring that your Google Cloud environment variables and Gemini prompts stay completely private.
