Perplexity

Strict HTML validation

Generating graphics programmatically usually involves silent failures when a CSS tag breaks. Pydantic AI forces the MCP Server `create_image` tool to validate its inputs against your predefined models before execution. If the agent hallucinates a malformed URL or forgets a required HTML wrapper, the framework fails loudly. This guarantees your `create_template` calls always receive structurally sound markup.

Typed image retrieval

Fetching generated files requires exact parameter matching. When your agent invokes `get_image`, it can specify exact crop dimensions and resize values through strictly typed query parameters. The response maps directly back to your Pydantic schemas. You can also run `list_images` to pull metadata for audit logs, knowing the returned JSON will match your expected types perfectly.

Pydantic AI MCP Server management

Managing cloud resources requires predictable state changes. The integration provides `get_usage` so your agent can verify API limits before starting a massive job. Cleanup is just as explicit. Calling `batch_delete_images` guarantees those temporary files vanish, preventing runaway storage costs from orphaned test renders.

Setup guide

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

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

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

Common questions about HTMLCSSToImage MCP in Pydantic AI

Install the slim package with MCP support. Then instantiate MCPToolset with your HTTP endpoint and pass it to your agent's toolsets array.

Pydantic AI validates the exact structure of the HTML and CSS before sending it to the tools. This stops hallucinated syntax from wasting your API quota.

Your agent can construct a list of up to 25 items and pass them to `batch_create_images`. The framework ensures the entire batch payload is typed correctly.

Pydantic AI catches the failure and raises a validation error immediately. Your agent can either retry with corrected HTML or halt the pipeline.

Any customer names or financial data embedded in the HTML templates are processed in an isolated, ephemeral sandbox. The container terminates the second the image renders, leaving no residual cache.
