unlockpdf-skill

Remove PDF password protection from any AI agent or tool.

Powered by unlockpdf.dev — 10 free unlocks/day, then $0.05 USDC per unlock via x402.

---

Copy `skill.md` and paste it into any AI tool's system prompt or instructions. Works with Claude, ChatGPT, Cursor, or any LLM.

What it does: Gives your AI the instructions to call unlockpdf.dev automatically when you ask it to unlock a PDF.

---

1. Open Claude.ai → Create a new Project
2. Go to Project Instructions
3. Copy and paste the contents of `claude-project.md`
4. Done — Claude will now automatically use unlockpdf.dev whenever you mention PDF passwords in that project

---

The MCP server lets Claude act fully autonomously — reading PDFs from your filesystem and saving unlocked files directly, no copy-paste needed.

cd mcp-server
npm install

Edit your Claude Desktop config file:

Mac: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "unlockpdf": {
      "command": "node",
      "args": ["/absolute/path/to/unlockpdf-skill/mcp-server/index.js"]
    }
  }
}

Restart Claude Desktop. You'll see "unlockpdf" appear in the tools panel.

Just tell Claude:

• *"Unlock the PDF at ~/Downloads/document.pdf, password is abc123"*
• *"Remove the password from this PDF and save it to my desktop"*
• *"How many free unlocks do I have left today?"*

Claude will call the MCP tools automatically.
