How to Use the ERS USDA (Economic Research) MCP in Google ADK

Q: How do I connect ERS USDA (Economic Research) to Google ADK?

Initialize a StreamableHttpServerParameters object with your Vinkius URL. Wrap that in an McpToolset and pass it to your LlmAgent tools array.

Q: How does the agent handle missing USDA variables?

It queries the metadata endpoints first. The agent runs getarmscategories to find the right data bucket before attempting to pull actual survey results.

Q: Does this work with Gemini's long context window?

Perfectly. The agent can pull massive lists from getarmsfarmtypes and getarmsstates and hold them all in memory while reasoning about regional agricultural trends.

Pull USDA economic data into Google ADK agents for deep agricultural analysis.

Query Survey Data via Google ADK

The `get_arms_surveydata` tool queries farm financial metrics based on specific years and variables. Your Gemini agent pulls this directly from the USDA Agricultural Resource Management Survey. Gemini's massive context window means you can dump decades of agricultural records into a single prompt. The agent grabs the data via HTTP transport and cross-references it against your existing BigQuery datasets in real time.

Audit Agricultural Variables

The `get_arms_variables` tool extracts detailed metadata for thousands of USDA economic indicators. Your agent uses this to understand exactly what a specific financial metric actually measures before running analysis. You can restrict which endpoints the agent sees using the `tool_names` filter in the `McpToolset`. If you only want the agent mapping definitions, you expose this tool alongside `get_arms_categories` and hide the raw survey data endpoints.

Map Regional Farm Reports via MCP

The `get_arms_reports` tool lists every available financial report published by the ERS. Agents call this to figure out which datasets exist for specific agricultural sectors. When combined with `get_arms_states` and `get_arms_farmtypes`, your Gemini model builds a complete mapping of regional farm structures. It maps out the metadata, decides which reports matter, and executes the queries autonomously.

Setup guide

Set up ERS USDA (Economic Research) 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 ERS USDA (Economic Research) 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="ERS USDA (Economic Research)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to ERS USDA (Economic Research) tools via MCP.",
    tools=mcp_tools,
)

Common questions about ERS USDA (Economic Research) MCP in Google ADK

Initialize a `StreamableHttpServerParameters` object with your Vinkius URL. Wrap that in an `McpToolset` and pass it to your `LlmAgent` tools array.

You define exactly what the agent accesses. Pass an array of specific tool names like `get_arms_surveydata` or `get_arms_years` to the `McpToolset` to restrict the agent's capabilities.

It queries the metadata endpoints first. The agent runs `get_arms_categories` to find the right data bucket before attempting to pull actual survey results.

Perfectly. The agent can pull massive lists from `get_arms_farmtypes` and `get_arms_states` and hold them all in memory while reasoning about regional agricultural trends.

Vinkius proxies your requests to the USDA API through a zero-trust architecture. Your agent pulls public farm debt-to-asset ratios and crop production metrics without exposing your Google Cloud credentials to the external server.
