How to Use the NationBuilder MCP in Google ADK

Q: How do I set up the Google ADK to work with my NationBuilder account?

You use the McpToolset in the ADK and point it to this server's URL. The toolset makes all the NationBuilder functions available to your Gemini agent. It's a few lines of Python to get started.

Q: Can I use a Google ADK agent to find specific people in NationBuilder?

Absolutely. The findsignupbyemail tool is designed for this. Your agent can take an email address as input and get back the correct supporter record from NationBuilder instantly.

Q: How do I sync NationBuilder data to BigQuery using the Google ADK?

Create an agent that periodically calls listnationsignups and listrecentdonations. The ADK lets you easily process the JSON output from this MCP server and append it to your BigQuery tables for analysis.

Q: Can my Google ADK agent check if the NationBuilder API is down?

Yes, the getapistatus tool is included for exactly this reason. You can build resilient workflows by having your agent check the connection before attempting to read or write data.

Connect Gemini agents to your NationBuilder data for large-scale campaign analysis with the Google ADK.

Analyze Supporter Lists at Scale

Pull your entire supporter list for analysis in your Google Cloud environment. The `list_nation_signups` tool lets your Gemini agent fetch supporter data directly from NationBuilder. You can pipe this data straight into BigQuery. Your agent can then use other tools to enrich this data. Use `get_signup_details` for specifics on a key donor or `list_signup_tags` to understand segmentation. This is how you move from just storing data to actually using it for strategy.

Integrate Events and Donations

Your agent can now see your full campaign calendar. The `list_upcoming_events` tool gives it a direct view of what's happening on the ground. This is perfect for building dashboards or sending automated reminders. It can also track fundraising in real time. An agent can use `list_recent_donations` to pull contribution data for financial modeling in a Colab notebook. This MCP Server makes NationBuilder another data source in your GCP ecosystem.

Build Workflows with your Google ADK Agent

Automate common organizing tasks. When a new person signs up at an event, an agent can use `create_new_signup` to add them to your nation. It can immediately follow up by logging their first contribution with `record_donation`. You can even have agents monitor petition activity with `list_nation_petitions`. Because the Google ADK integrates with other Google services, you could trigger a Vertex AI pipeline when a petition hits a certain signature count. It's all connected.

Setup guide

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