How to Use the Georef Argentina MCP in Pydantic AI

Q: How do I configure Georef Argentina with Pydantic AI?

Instantiate MCPToolset with your Vinkius server URL and pass it to the Agent constructor. The framework automatically discovers tools from the MCP Server like normalizedireccion and validates their inputs and outputs at runtime.

Run type-safe Argentine address validation and reverse geocoding inside your Pydantic AI workflows with zero silent failures.

Type-safe address validation for Pydantic AI

Ensure your agent never processes a malformed Argentine address. By calling `normalize_direccion`, your agent parses street strings and validates them against strict Python schemas at runtime. If the upstream government database returns unexpected data, the framework catches it instantly. This prevents corrupted coordinates from entering your database, ensuring your shipping pipeline remains clean and predictable.

Map administrative divisions with this MCP Server

Your agent can query the exact hierarchy of Argentine geography using `get_provincias`, `get_departamentos`, and `get_municipios`. The framework enforces strict type checking on every returned ID and name. This MCP Server integration eliminates silent errors. If an agent tries to assign a locality to the wrong department, the model catches the validation mismatch immediately and corrects its reasoning path.

Strict coordinate verification and lookup

Convert GPS coordinates into structured administrative zones with absolute type safety. Your agent runs `reverse_geocoding` to resolve latitude and longitude into official localities. You can then use `get_localidades` or `get_vias` to cross-reference the street grid. Because every response matches a strict Pydantic model, your downstream application can ingest the geographic data without parsing errors.

Setup guide

Set up Georef Argentina 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": {
        "georef-argentina-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Georef Argentina tools.",
)

result = await agent.run("List recent Georef Argentina transactions")
print(result.output)

Common questions about Georef Argentina MCP in Pydantic AI

Instantiate `MCPToolset` with your Vinkius server URL and pass it to the `Agent` constructor. The framework automatically discovers tools from the MCP Server like `normalize_direccion` and validates their inputs and outputs at runtime.

Pydantic AI will raise a validation error at runtime instead of letting your agent hallucinate. This guarantees that messy data from `get_vias` or `get_localidades` is caught before it breaks your database.

Yes, the framework is model-agnostic. You can connect local models or commercial APIs to this server, allowing any model to parse Argentine administrative boundaries using `get_departamentos`.

Writing custom validation schemas for Argentine geography is tedious and prone to errors. This server exposes official government data instantly, saving you from writing boilerplate code for administrative lookups.

The MCP Server runs in an ephemeral, zero-trust sandbox on Vinkius. Your address strings and coordinates are never stored, and the connection to the official government API is fully encrypted during transit.
