How to Use the ExchangeRate-API MCP in Google ADK

Q: Can I limit which ExchangeRate-API tools my Google ADK agent can see?

Yes. Use the toolnames parameter when defining your McpToolset to expose only specific tools like convertcurrencypair while hiding historical lookup tools.

Q: Can Gemini use historical rates to predict currency trends?

Yes. Your agent can call gethistoricalrates to pull past data, then use Gemini's long-context reasoning to analyze shifts in currency values over months or years.

Feed live FX rates directly into your Gemini enterprise pipelines using Google ADK and BigQuery data.

Context-rich currency analysis in Google ADK

The `get_enriched_currency_data` tool provides full currency names, regional details, and flag information directly to your Gemini model. This extra context helps your agent generate user-facing financial reports that require formal currency names instead of raw three-letter codes. Because Google ADK supports massive context windows, your agent can ingest enriched data from this MCP Server for dozens of currencies simultaneously. This allows the model to perform deep reasoning on global market distributions without running out of memory.

Automating BigQuery pipelines with this MCP Server

The `get_latest_rates` tool fetches real-time exchange rates that your agent can write into BigQuery tables. Your enterprise agents can run scheduled checks, pull the latest spot rates, and update your internal pricing databases without manual intervention. You configure this by passing the McpToolset to your LlmAgent in your Python code. The agent coordinates the API calls and routes the currency data directly to your Google Cloud storage or analytics pipelines.

Multi-currency conversion for enterprise billing

The `convert_currency_pair` tool calculates exact conversions between billing currencies and local payment methods. Your agent invokes this tool to determine the correct invoice amounts before generating billing documents or updating ERP records. You can use the tool_names filter in Google ADK to expose only this specific MCP tool to your billing agent. This limits the agent's scope, ensuring it focuses purely on calculations without accessing historical rate tools.

Setup guide

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