Validate document formats with Pydantic AI

The `convert_document` tool changes file formats, and `get_document_statistics` returns structured metadata. This MCP Server lets Pydantic AI validate these outputs against strict Python types at runtime, preventing corrupt file structures from slipping through your code. If the server returns unexpected data formats during a file conversion, your agent fails immediately with a validation error. This guarantees that your downstream storage workflows never receive malformed document payloads.

Edit and protect documents using this MCP Server

The `replace_text_in_document` tool updates text variables, and `protect_document` applies password security. Pydantic AI ensures that the text replacements and password parameters match your exact schema requirements before calling the server. Your agent can run `accept_all_revisions` to clean up tracked changes. Because every input is validated, you don't have to worry about your agent passing null values or incorrect arguments to the document protection tools.

Split and render pages safely in Pydantic AI

The `split_document` tool divides files into pages, and `render_document_page` outputs specific pages for visual checks. Pydantic AI validates the page numbers and output paths, catching logical errors before the rendering process starts. You can use `list_cloud_files` to verify file existence before running these tools. The validated file lists prevent your agent from attempting to split non-existent documents.

Setup guide

Set up Aspose.Words 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": {
        "asposewords-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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