Validate stock earnings data in Pydantic AI

`get_earnings` retrieves historical earnings reports, beats, and misses, feeding them directly into your Pydantic AI agent. The framework validates every financial field against strict schemas before your code executes. If the API structure changes or returns unexpected null values, your agent raises a validation error immediately. This prevents corrupted financial metrics from polluting your Pydantic AI automated trading decisions.

Fetch type-safe cryptocurrency price feeds

`get_crypto_daily` pulls daily price data for any crypto symbol against your chosen market currency. The Pydantic AI toolset ensures the returned dates and price floats match your exact data models. You pass the configured MCPToolset directly to your agent. Because the framework is model-agnostic, you can switch from OpenAI to local models while maintaining identical validation rules for crypto data.

Get real-time stock quotes with strict schemas

`get_quote` pulls current trading prices, change percentages, and volume metrics for instant verification. Your Pydantic AI agent uses this tool to check current market levels before placing orders. The Pydantic AI framework guarantees that every field in the real-time quote conforms to your expected types. This eliminates silent failures where an agent might read a string instead of a float during rapid price swings.

Setup guide

Set up Alpha Vantage 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": {

)

result = await agent.run("List recent Alpha Vantage transactions")
