Perplexity

Validate App Configuration via MCP Server

The agent first calls `list_menu` to get the current custom menu structure. Because of Pydantic, you'll get a perfectly typed JSON object back—no unexpected fields or missing keys. This ensures that any subsequent tool call based on app configuration is structurally sound before it executes.

Manage User Cohorts using WeCom / 企业微信

To find a specific group, the agent uses `get_tag_users` and receives a list of user IDs validated against your Pydantic schema. If the API sends garbage data, the process fails loud and clear. This level of type safety is critical when dealing with sensitive employee records or large lists.

Send Structured Communications via Pydantic AI

Sending a message requires more than just text. By using `send_message`, the agent ensures the recipient ID and the payload format conform exactly to your defined models. This prevents common errors like sending messages to non-existent IDs, keeping your communications reliable.

Setup guide

Set up WeCom / 企业微信 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.

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.
