Let your AI agent do the PDF work
Claude and other AI agents can call Orihako's tools and recipes through MCP. The files stay on your computer; the AI only asks for the work.
- Download the agent: Unzip it into a folder you keep, for example your user folder. It holds one script, the PDF engine and a font.
- Install Node.js: The agent runs on Node.js 20 or later. Download the LTS version from the official site and install it with the default settings.
- Connect your AI app: Choose your app and copy the setting. Replace the folder with the place you unzipped the agent to.
What to ask
- Compress every PDF in my Downloads folder to under 3 MB and put the results in Downloads/small.
- Merge the contracts in Desktop/deal in order, number the pages and add a bookmark per file.
- Make a recipe that flattens, removes author info and compresses to 2 MB, check it, then run it on these three files.
- How many pages does report.pdf have, and is it a scan without text?
Free and Pro with an agent
Asking for one tool on one file is free. Several steps, several files at once, conditions and name rules need a Pro key, activated once on the computer (the agent tells you how).

Safety
- Files are read only from the paths the agent names, and processed on your computer; nothing is uploaded.
- Results are written only into the output folder, never over an existing file unless asked.
- Steps that cannot be undone (redaction, flattening, compression…) run only after the agent has checked with you.
- Your originals are never changed. Passwords are used for one run and never stored.
Questions and answers
What is MCP?
The Model Context Protocol: an open standard that lets AI apps call tools on your computer. Claude Desktop, Claude Code, Cursor and many others support it.
Does the AI see my files?
The agent works on the files locally and tells the AI only what happened: names, page counts, sizes and notes. The AI app may read files you attach to the chat itself; Orihako does not send them.
Does it need the internet?
Processing does not. Activating a Pro key and its daily check do, as in the browser.
Can I schedule it without an AI?
Yes. Run the command line from a scheduled task, for example: node orihako.mjs recipe run send.orihako in/*.pdf -o out --yes
