How to Use the HelloAsso MCP in Google ADK

Q: How do I restrict which HelloAsso tools my Google ADK agent can use?

You can use the toolnames filter within the McpToolset configuration. This allows you to whitelist only the specific tools, like listforms, that your agent requires.

Integrate HelloAsso with your Google ADK agents to unify non-profit management with your BigQuery and Vertex AI workflows.

Sync campaign forms with Google ADK

Access your entire campaign portfolio using `list_forms`. This tool identifies every active event, donation drive, or membership form associated with your non-profit account. Deepen your analysis by pulling granular data from specific forms. Use the `formSlug` returned by the list tool to fetch detailed order history via `list_sold_items`, giving your Gemini-powered agent full context on what your supporters are buying.

Direct payment and order management

Execute `list_orders` to pull every transaction group into your Google ADK environment. This allows you to cross-reference purchase data with your existing cloud infrastructure. Validate individual transactions using `get_order_details`. If you need to confirm specific item quantities or payment statuses, this tool provides the raw data your agent needs to make informed decisions.

Streamline organization administrative tasks

Use `list_my_organizations` to map out all accounts your user credentials can access. This is the first step in setting up a multi-tenant agent that manages several non-profits simultaneously. Retrieve specific organizational metadata with `get_organization_details`. Your agent can use this information to gate actions or verify that it is operating within the correct account context before processing any payment data.

Setup guide

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

Common questions about HelloAsso MCP in Google ADK

Use the McpToolset class to connect your server URL. You can then pass this toolset to your LlmAgent to start executing operations like `list_payments` directly.

Yes. Gemini models have large token windows, making them ideal for processing the output of tools like `list_orders` or `list_sold_items` when analyzing big batches of historical data.

Your data is handled through a secure MCP transport layer. Only the specific member details you request are passed to the agent, and the server remains ephemeral.

You can build an automated pipeline that periodically calls `list_payments` and sends the results to BigQuery. This allows your agent to generate reports based on live HelloAsso data.

You can use the tool_names filter within the McpToolset configuration. This allows you to whitelist only the specific tools, like `list_forms`, that your agent requires.
