Perplexity

Bridge BigQuery data with donor records

`list_donor_constituents` pulls your active constituent list directly into Gemini's massive context window. The Google ADK lets your enterprise agent read thousands of donor profiles at once, matching them against offline tables stored in BigQuery. This integration lets you identify lapsed donors without complex SQL joins. The agent reads your database, cross-references it with your cloud storage, and highlights profiles that need attention.

Google ADK drives campaign allocation

`list_organizational_funds` allows your agent to query available internal accounts and map them to active fundraising efforts. This MCP Server lets you map incoming funds to the correct cloud-tracked projects by combining this tool with `list_fundraising_campaigns`. You can restrict the exposed tools using the ADK's name filter. If you only want your agent to report on campaigns without modifying data, you can expose `list_fundraising_appeals` while blocking write tools.

Write back donations securely from the cloud

`record_new_donation` writes verified transaction data back to your CRM after your pipeline processes a bank deposit. The Google ADK executes this write securely, ensuring your donor database reflects real-world bank feeds immediately. Before writing, the agent calls `get_donor_details` to verify the target constituent exists. If the donor is missing, the agent calls `create_new_donor` to build a clean profile first, maintaining database integrity.

Setup guide

Set up Little Green Light 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 Little Green Light 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="Little Green Light_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Little Green Light tools via MCP.",
    tools=mcp_tools,
)

Common questions about Little Green Light MCP in Google ADK

Use the toolset class with your Vinkius HTTP server parameters. Pass this toolset directly into the tools list of your Gemini LlmAgent to expose the CRM tools.

Yes. Gemini's long context window allows you to pass large lists of constituents retrieved via `list_donor_constituents` directly into the prompt. The agent can then iterate through the list and update records sequentially.

Yes. The ADK supports both transport protocols for the MCP. For production cloud deployments on Vertex AI, the streamable HTTP transport hosted on Vinkius is the recommended approach.

You can pass a list of specific tool names to the toolset constructor. This prevents the agent from seeing or executing administrative tools like `record_new_donation` if it only needs read access.

Your API key is stored securely within the Vinkius vault and injected at the sandbox level during runtime. It never travels through Google Cloud or the Gemini model APIs, keeping your financial records isolated.
