Yes. Every response from tools like getvoterinformation is checked against runtime type models, preventing silent data failures in your pipeline.

Perplexity

Parse representatives with Pydantic AI validation

The `get_representatives_by_address` tool retrieves elected officials and their contact details for any given physical address. Pydantic AI enforces strict runtime validation on the returned JSON payload, ensuring no missing fields break your application. If the civic API returns a non-standard address format, the framework raises a validation error immediately. This prevents your agent from operating on corrupted or incomplete political representative profiles.

Look up voter information safely

The `get_voter_information` tool fetches polling places, voter registration rules, and ballot details. It maps these complex data structures directly to your application's defined schemas. Combine this tool with `get_google_civic_elections` to identify current voting events. The agent validates each election ID against strict type definitions before querying the voter info endpoint.

Map divisions and verify API health

The `search_civic_divisions` tool resolves municipal and state boundaries into standardized OCD-IDs. Your agent uses these IDs to query specific local government jurisdictions without guessing the naming conventions. Running `check_api_status` first ensures your type-safe agent doesn't waste execution cycles on unresponsive upstream government data feeds.

Setup guide

Set up Google Civic Information 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({
