Ask your agent to work with local PDF files through KillerPDF.

Install KillerMCP

KillerMCP includes all 81 KillerTools utilities plus tools from supported Killer apps in one local connection. You will not need a separate KillerPDF MCP installer, a source checkout, Node, or a list of commands.

Download for Windows
Version 0.1.036.6 MiBDigitally signedHosted on GitHub Releases
  1. Download and run KillerMCP Setup. Use the signed installer above.
  2. Let setup connect your agent. It installs the shared runtime and registers KillerMCP with Codex, Claude Code, Claude Desktop, Cursor, GitHub Copilot, Gemini CLI, and Windsurf when found.
  3. Open a new agent chat and ask. KillerMCP detects KillerPDF on your computer and makes its PDF tools available through the same connection.

Hosted KillerTools

Optional access to 64 web based utilities without installing KillerMCP. This connection cannot use local files or Killer app tools.

Use the same URL in Cursor, VS Code, Claude, or another MCP client.

Try asking:

killer is the shortest form. Your agent can infer KillerPDF when the request and attached files are clearly about PDFs. Use killerpdf only when you want to make the app explicit.

What it can do

KillerMCP uses every headless operation advertised by the installed KillerPDF version. The released 1.8 line provides ten tools, and newer builds can add preflight and accessibility reports automatically.

Merge PDFsCombine two to eight local PDFs into one new document in the requested order.
Extract or split pagesPull a page range into a new PDF or create one PDF per page.
Remove encryptionCreate an unencrypted copy, using a password when the source requires one.
Render pagesCreate PNG or JPEG images for all pages or a selected range.
Flatten documentsCreate a raster PDF whose original editable content is no longer editable.
Print selected pagesSend a real print job to the default printer or a named printer.
Run OCRCreate a searchable PDF with the selected OCR language.
Resave and benchmarkUse KillerPDF's standard save pipeline or collect bounded render timing output.
Inspect newer buildsRun preflight and accessibility reports when the installed version advertises them.
Protect existing outputFile-producing tools require a new path and refuse to overwrite existing files or folders.

Data safety and permissions

PDF operations run locally through the installed KillerPDF app. The Cloudflare Worker never receives the files. File-producing tools stage their output and refuse to overwrite an existing path. Preflight and accessibility checks are read-only. Printing sends a real local print job. OCR can download a selected language model from the Tesseract project on first use.

Your MCP client and model provider can still receive file paths and returned report data. Review the requested paths, printer, and operation before approval and apply the provider data handling rules to confidential documents.

How it works

KillerMCP is an open-source local runtime. It includes all 81 KillerTools utilities, detects installed Killer apps, and exposes only the adapters supported by those versions. For this page, it validates paths and limits before calling KillerPDF, stages new output, and validates the result.

The optional public endpoint is a separate open-source MCP server running as a Cloudflare Worker. Requests sent there are processed on Cloudflare. It offers web based KillerTools utilities but cannot reach local PDF files or invoke KillerPDF.

Current limits

Each source PDF is limited to 64 MiB. Merge accepts 2 to 8 PDFs with combined inputs up to 128 MiB. Page ranges, DPI, copy counts, render sizes, and benchmark page counts are bounded. Password protected files require the correct password. OCR may require a language download. Preflight and accessibility reports appear only when the installed KillerPDF build advertises them.

One connection for the family

Install KillerMCP once. It detects supported Killer apps on your computer and adds their tools to one agent connection. As more app integrations are released, the same KillerMCP runtime can provide them without a separate installer for every app.
