How to Use the PDF Munk MCP in Pydantic AI

Q: How does Pydantic AI validate PDF Munk tool outputs?

The framework wraps every tool in the MCP Server, such as generatepdffromurl, in a Pydantic model. If the server returns data that violates your schema, the client raises a validation error immediately.

Q: Can my agent check the status of PDF Munk within Pydantic AI?

Yes, you can invoke checkpdfmunkstatus to verify server connectivity before starting a heavy generation run. This prevents runtime failures during long-running tasks.

Q: How does the PDF Munk MCP Server handle template listing in Pydantic AI?

Your agent calls listtemplates to retrieve a verified array of available layouts. Pydantic AI parses this array into typed objects, making it easy to select the correct template ID safely.

Q: Can I split PDFs using type-safe agents?

Yes, the splitpdf tool takes a file path and returns a validated list of paths for the separated pages. Your agent can immediately process these split files knowing the schema is correct.

Enforce strict runtime type safety on PDF Munk document generation pipelines using Pydantic AI agent schemas.

Type-safe document generation with Pydantic AI

PDF Munk integrates with your type-safe agent workflows to guarantee that inputs to `generate_pdf_from_html` match your expected Pydantic AI schemas. Pydantic AI validates the HTML string and CSS variables before hitting the MCP Server. When pulling layouts, your Pydantic AI agent uses `get_template` to enforce structural definitions before calling `generate_pdf_from_template`. This ensures that any call to the generation endpoint contains the exact fields your template expects.

Validated PDF manipulation and compression

Managing file structures is safe when using the `merge_pdfs` tool within your Pydantic AI validation pipeline. The agent validates the list of file paths against a strict Pydantic model before starting the merge process. If files exceed your limits, your Pydantic AI agent runs `compress_pdf` to reduce storage footprints while validating the output metadata. The tool returns validated file metadata so your system never processes corrupt or incomplete PDFs.

Automated layout checks via an MCP Server

Generating visual assets is highly predictable using the `generate_image` and `generate_screenshot` tools inside Pydantic AI. The agent receives structured image metadata that conforms to your application's data models. To protect intellectual property, your Pydantic AI agent applies visual stamps using `add_watermark` after validating the input document schema. If the source document fails validation checks, the pipeline halts immediately, preventing unwatermarked files from escaping.

Setup guide

Set up PDF Munk 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": {
        "pdf-munk-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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