Type-safe HTML output for Pydantic AI

Stop guessing if your agent generated valid markup. This integration validates the output of the `compile_markdown` tool against strict Python types at runtime. If the MCP Server returns anything unexpected, your agent fails loudly. This strict validation prevents silent layout corruption in your production apps. You get clean, minified HTML that matches your exact schema definitions every single run.

Model-agnostic compilation via MCP Server

Whether you run Claude, GPT-4, or a local model, your Pydantic AI agent gets uniform HTML output. By offloading the conversion to this MCP Server, you bypass model-specific formatting quirks. The `compile_markdown` tool acts as a single source of truth. This consistency makes switching backend models trivial. Your output HTML remains identical even if you swap your entire LLM provider overnight.

Prevent broken HTML tags in your CMS templates

Models often hallucinate closing tags or mess up nested lists. Using the `compile_markdown` tool ensures that your Pydantic AI agent only outputs structurally sound, minified HTML. The compilation happens outside the LLM, eliminating syntax errors. Your system can confidently push these outputs directly to your production CMS. No human review is needed to verify the markup structure.

Setup guide

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.

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
