How to Use the ECB Exchange Rates — Official EUR Reference Rates MCP in Pydantic AI

Q: How do I initialize the ECB Exchange Rates — Official EUR Reference Rates MCP Server inside Pydantic AI?

Install the package via pip install "pydantic-ai-slimmcp" and instantiate MCPToolset with the server's HTTP URL. Pass this instance to the toolsets parameter of your Agent to expose the tools.

Q: How does Pydantic AI validate data returned by the ECB Exchange Rates — Official EUR Reference Rates MCP Server?

The framework automatically wraps the JSON payloads from getlatestrates in Pydantic models. If the ECB feed contains a malformed rate or unexpected currency code, the agent raises a validation error immediately.

Type-safe EUR rate retrieval in Pydantic AI

See for yourself: the `get_exchange_rate` tool fetches official EUR reference rates with strict schema validation at the runtime level. If the feed returns unexpected structures, your Pydantic AI agent fails loudly, preventing corrupted financial data from slipping into your application. You configure this by importing `MCPToolset` and pointing it to the server's HTTP endpoint. The toolset automatically maps the ECB's daily, monthly, or annual frequency outputs to type-safe Python models.

Validate the full daily snapshot using this MCP Server

The `get_latest_rates` tool pulls the entire list of active currency pairs published daily at 16:00 CET. Your agent parses USD, GBP, JPY, and CHF, validating each rate against strict float and string schemas to ensure mathematical accuracy. This MCP Server eliminates silent errors in your data pipeline. Because Pydantic AI is model-agnostic, you can use these validated rates with any LLM provider while maintaining strict structural guarantees.

Compare multiple currency pairs with strict schemas

The `get_multiple_rates` tool allows your agent to request several currency codes simultaneously via a comma-separated list. The agent parses the returned EUR rates, ensuring every currency code matches the expected ISO standard before processing. By passing the toolset as `toolsets=[toolset]` to your Agent, you bypass complex custom validation code. The system handles the underlying SSE or Streamable HTTP transport while keeping your agent's decision-making loop clean and predictable.

Setup guide

Set up ECB Exchange Rates — Official EUR Reference Rates MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "ecb-exchange-rates-official-eur-reference-rates-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to ECB Exchange Rates — Official EUR Reference Rates tools.",
)

result = await agent.run("List recent ECB Exchange Rates — Official EUR Reference Rates transactions")
print(result.output)
