How to Use the Certn MCP in Pydantic AI

Q: How do I fetch Certn packages safely using Pydantic AI?

Execute the listpackages tool to retrieve available background check options. Pydantic AI validates the package structure, making sure your agent selects a valid configuration for addhrpackages.

Q: Can Pydantic AI handle Certn tenant screening applications?

Yes, the agent calls listpmapplicants to track prospective tenants. The framework validates every applicant record, preventing runtime crashes caused by unexpected null values in tenant histories.

Q: How does Pydantic AI retrieve Certn PDF reports?

The agent uses gethrreportpdf to download the official background check document as a binary stream. You can also call gethrreportlink to get a validated, temporary URL for web access.

Execute type-safe Certn background checks with strict runtime validation using Pydantic AI.

Validate applicant data structures with Pydantic AI

The `get_hr_applicant` tool fetches candidate screening statuses and parses them directly into typed Python objects. If Certn returns unexpected fields, your Pydantic AI agent catches the validation error instantly. You can also use `list_hr_applicants` to query your entire candidate pipeline. Pydantic AI ensures that every Certn record matches your schema before your application processes the background check status.

Initiate secure background checks via this MCP Server

The `invite_hr_application` tool triggers candidate invitations with strict parameter validation. This MCP Server ensures that email addresses and phone numbers conform to expected formats before initiating the Certn check. For instant checks, `quick_hr_application` executes background screenings with immediate results. Your Pydantic AI agent validates the output payload against your Pydantic models to guarantee data integrity.

Manage rental properties with strict type safety

The `create_pm_property` tool creates new real estate records using validated input models. Pydantic AI prevents malformed property details from reaching the Certn API, reducing runtime errors. To verify your property database, `list_pm_properties` retrieves all active units. The Pydantic AI framework validates the returned property list, ensuring your agent works with clean, structured data.

Setup guide

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

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

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