How to Use the PDF Munk MCP in LlamaIndex

Q: How do I index documents generated by PDF Munk in LlamaIndex?

Use the McpToolSpec to load the tools into your LlamaIndex agent. When the agent calls generatepdffromhtml, save the output file to a local directory and use a standard PDF reader to index its contents into your vector store.

Q: Can LlamaIndex query my existing PDF Munk templates?

Yes. Your agent can run listtemplates to retrieve all available designs, then index those metadata descriptions. This lets the query engine match user requests to the most relevant template.

Q: Does the PDF Munk toolset support async execution in LlamaIndex?

Yes, you can load the tools asynchronously using totoollistasync(). This prevents long-running tasks like generatepdffromurl from blocking your main query pipeline.

Q: How do I protect document layout quality?

Use generatepdffromhtml with inline CSS to guarantee consistent layouts. The underlying engine renders modern styles accurately, so your generated files look identical to your web previews.

Index and search your generated PDFs directly within your LlamaIndex knowledge graphs.

Perplexity

Feed generated document metadata into your LlamaIndex index

This MCP Server lets your LlamaIndex agent generate files and index them in one clean step. When the agent runs `generate_pdf_from_template`, it can immediately index the resulting document's text and metadata back into your vector store. This means your RAG application always has access to the exact documents it just created. If a user asks about a report generated five minutes ago, the query engine searches the indexed output of `get_template` and retrieves the correct context.

Turn live web pages into searchable document nodes

Stop dealing with messy web scrapers that break on dynamic JavaScript. Use `generate_pdf_from_url` to grab a clean, styled PDF of any live URL, then let LlamaIndex parse that PDF into clean text nodes. If you just need a quick visual check, the agent can call `generate_screenshot` or `generate_image` instead. The resulting files are stored in your document directory, ready for downstream indexing or visual analysis.

Split and restructure documents for RAG optimization

Large PDFs make terrible retrieval units because they dilute context. Your LlamaIndex agent can use this MCP toolset to run `split_pdf` to break massive files into single pages before embedding them. Conversely, if your retrieval engine needs to compile a custom reference manual from multiple sources, the agent calls `merge_pdfs`. It groups relevant pages together, runs `compress_pdf` to keep the index light, and presents a single clean document to the user.

Setup guide

Set up PDF Munk MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all PDF Munk MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to PDF Munk tools.",
)
response = await agent.run("List recent PDF Munk data")
