How to Use the Charity Navigator MCP in Google ADK

Q: How do I load Charity Navigator tools in Google ADK?

Install the google-adk package and set up an McpToolset with your HTTP URL parameters. Pass that toolset directly to your LlmAgent to expose the endpoints.

Q: Can Google ADK restrict which Charity Navigator tools the agent sees?

Yes, you apply a toolnames filter during setup. This prevents the agent from running broad searches if you only want it checking specific EINs for advisories.

Connect Charity Navigator to Google ADK and let Gemini agents run deep financial analysis on nonprofits across 1M+ tokens.

Perplexity

Feed Charity Ratings into Google ADK

Enterprise agents need massive context windows to evaluate philanthropic impact. You connect this MCP Server, and Gemini pulls entire historical datasets using `get_charity_ratings` to analyze long-term accountability trends. Cross-referencing this data with your internal BigQuery tables happens instantly. The agent matches your corporate giving history against current transparency scores to flag declining financial health.

Run Deep Governance Audits

Risk management requires checking every single warning flag. Your Vertex AI pipeline can hit `get_charity_advisories` to pull active and removed alerts regarding a nonprofit's fundraising practices. Long-context reasoning shines when you feed it raw advisory text. Gemini reads the specific operational concerns alongside the base `get_charity` tax filings to generate a conclusive risk assessment.

Map Philanthropic Causes at Scale

Categorizing thousands of organizations manually wastes engineering hours. The `get_categories` tool gives your agent the exact ID structures needed to filter searches by environment, health, or education. Scaling this through the `search_charities` MCP endpoint allows bulk extraction. You pull up to 1000 records per page, grabbing EINs and mission statements to populate your Vertex AI vector databases.

Setup guide

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

Common questions about Charity Navigator MCP in Google ADK

Install the `google-adk` package and set up an `McpToolset` with your HTTP URL parameters. Pass that toolset directly to your `LlmAgent` to expose the endpoints.

Yes, you apply a `tool_names` filter during setup. This prevents the agent from running broad searches if you only want it checking specific EINs for advisories.

The framework manages the page parameters natively. When querying large cause categories, Gemini increments the `pageNum` argument up to the limit of 10 to gather the full dataset.

The MCP toolset drops right into any standard Gemini agent configuration. You define the transport layer, and the model starts executing API calls alongside your existing cloud functions.

The MCP integration runs through an ephemeral zero-trust endpoint. Your prompts containing proprietary corporate donation strategies never leak into the public nonprofit search queries.
