How to Use the Genderize MCP in Pydantic AI

Q: How do I register Genderize with Pydantic AI?

Use the MCPToolset class with your MCP Server HTTP endpoint. Pass the toolset to your agent to auto-register estimategender and other tools.

Q: Can Pydantic AI handle bulk Genderize lookups?

Yes. The estimategendersbulk tool allows your agent to validate and process arrays of names in a single step.

Q: How does Pydantic AI validate regional Genderize tools?

Tools like estimategenderus return structured data that the agent maps to strongly-typed models, guaranteeing runtime safety.

Q: How do I test the connection before running validation?

Call verifyapiconnection within your agent's startup sequence. This ensures the endpoint is reachable before processing names.

Validate name-based gender predictions with runtime type safety using the Genderize MCP Server and Pydantic AI.

Perplexity

Enforce strict type validation on name queries

The `estimate_gender` tool returns a structured payload containing the name, predicted gender, probability score, and count. Your Pydantic AI agent validates this response against strict Python models at runtime, failing loudly if the API returns unexpected formats. This prevents silent data corruption in your backend systems during name classification. If the Genderize API returns a null value or an unexpected schema, Pydantic AI catches it before your database updates.

Process validated lists using this MCP Server

Bulk enrichment operations use `estimate_genders_bulk` to validate lists of first names in a single structured transaction. Your Pydantic AI agent maps the list to a type-safe schema, ensuring every object in the array meets your data standards. Using this MCP Server allows your agent to handle multi-name lookups without losing type safety. The Pydantic AI agent parses the array response directly into a validated list of Genderize models.

Validate regional predictions with type-safe tools

Country-specific queries rely on `estimate_gender_us`, `estimate_gender_uk`, `estimate_gender_brazil`, `estimate_gender_spain`, and `estimate_gender_france` to return region-locked statistical data. Your Pydantic AI agent routes names to these tools based on validated user profiles. The Pydantic AI framework ensures that the regional probability outputs from Genderize conform to your data structures. This is critical when your database requires exact decimal precision for demographic scoring of names.

Setup guide

Set up Genderize 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": {
        "genderize-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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