How to Use the World Time (Keyless) MCP in Pydantic AI

Q: How does Pydantic AI validate World Time (Keyless) data?

When the agent calls getcurrenttime, Pydantic validates the response structure immediately. It checks that the returned atomic time, offset, and DST status match your expected data types.

Q: Does Pydantic AI require me to check all time zones with World Time (Keyless)?

You can use listavailabletimezones to get a complete list of supported regions. This helps you build the most robust tool definitions for your agent.

Perplexity

Get accurate global atomic times.

The agent calls `get_current_time` and gets the exact current atomic time, UTC offset, and DST status. Crucially, Pydantic validates this output against your defined model. You won't get silent corruption. If the API response is malformed, the agent fails loudly with a validation error.

Validate all available time zones.

Before running any logic, use `list_available_timezones` to check what regions exist. The returned data—a list of strings—is immediately validated by Pydantic. This means the agent knows *for sure* that every timezone string it handles is valid before proceeding with its task.

Build type-safe time workflows.

You wrap the MCP toolset and pass it to your Agent. The framework ensures that any data returned by `get_current_time` or `list_available_timezones` adheres strictly to your Python types. This guarantees correctness, which is more important than speed when dealing with critical time measurements.

Setup guide

Set up World Time (Keyless) 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": {
        "world-time-keyless-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent World Time (Keyless) transactions")
print(result.output)
