Perplexity

Structured account data retrieval

You need reliable user metrics and identity data. Your agent can call `get_phone_number` to grab the number, or use `get_account_status` to verify connectivity. Because Pydantic validates the output, you never get a field that doesn't exist. This is huge for correctness. If the API suddenly changes its response format, your agent fails loudly—you know exactly where the break is, instead of silently using bad data.

Automated content moderation

Use `image_security_check` and `message_security_check` to validate user-generated content before action. These tools return structured results that your Pydantic schema expects, so you can reliably build logic around clean data. This guarantees that the output used in subsequent steps—like sending a message—is safe and predictable.

Tracking user journeys

Grab performance metrics using `get_visit_page_trend` or check daily trends with `get_daily_summary`. These tools give you structured data points on engagement that are immediately usable in your models. The type-safe nature means the agent can treat these trend numbers as guaranteed floats or integers, which is exactly what you want when building production pipelines.

Setup guide

Set up WeChat Mini-Programs / 微信小程序 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({
