Fill documents through your AI app

Connect FormDD to your own AI app, such as Claude Desktop, and just type what you need — for example "Make certificates for everyone in D:\class1.xlsx, one PDF per person". FormDD has no built-in AI, and this costs nothing extra.

Download Setup (Windows) Install guide and SmartScreen warning

AI connection needs the Setup (.exe) version — the Microsoft Store version cannot connect yet.

What you need

  • FormDD 0.6.6 or later, installed from the website (Setup .exe), with a license key — the Microsoft Store version is not supported yet
  • An MCP-capable AI app on the same PC, such as Claude Desktop (free at claude.ai/download), Antigravity, Cursor or Codex
  • A template (fields placed) for the form you want to fill, or one of the ready-made forms that ship with FormDD

ChatGPT and Claude on the web cannot connect: they only reach online services, not programs on your PC.

Option 1 — Set up Claude Desktop yourself

  1. Quit Claude Desktop completely — right-click the Claude icon next to the clock → Quit (closing the window is not enough; while Claude runs it overwrites the file you edit)
  2. Press Windows + R, paste the line for your install and press Enter

    Claude from the Microsoft Store:

    notepad %LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json

    Claude downloaded from the web:

    notepad %APPDATA%\Claude\claude_desktop_config.json
  3. If the file is empty, paste all of this and replace YourName with your Windows user name 
    {
  "mcpServers": {
    "formdd": {
      "command": "C:\\Users\\YourName\\AppData\\Local\\Programs\\PDFFormMarker\\FormDD-mcp.exe"
    }
  }
}

    If the file already has content, send it to us by email and we will edit it for you, free (one misplaced bracket and Claude cannot read the file).

  4. Press Ctrl + S to save, then start Claude Desktop again
  5. Test: type "What forms does FormDD have?" — if you get a list of forms back, you are connected

Option 2 — Ask your AI to set it up

If you use an AI that can edit files and run commands on your PC (Claude Code, Codex, Cursor, Antigravity), copy this and give it as your request:

Connect FormDD to Claude Desktop on this Windows PC via MCP.
- FormDD's MCP program: %LOCALAPPDATA%\Programs\PDFFormMarker\FormDD-mcp.exe (check it exists)
- Claude Desktop config: if Claude is from Microsoft Store use
  %LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json
  otherwise %APPDATA%\Claude\claude_desktop_config.json
- Fully quit Claude Desktop first (it overwrites the file while running).
- Back up the file, then add a top-level "mcpServers" entry named "formdd" whose
  "command" is the full path above. Keep everything else; the result must be valid JSON.
- Start Claude Desktop again. Do not change anything else.

Claude Desktop's plain chat cannot reach files on your PC, so it cannot configure itself — use Option 1.

Other AI apps

Every app points to the same program, %LOCALAPPDATA%\Programs\PDFFormMarker\FormDD-mcp.exe. Edit the file while the app is closed, then start it again.

AppConfig fileAdd
Antigravity%USERPROFILE%\.gemini\antigravity\mcp_config.jsonSame as Claude (mcpServers)
Cursor%USERPROFILE%\.cursor\mcp.jsonSame as Claude (mcpServers)
Codex%USERPROFILE%\.codex\config.toml[mcp_servers.formdd] then on the next line command = '…\FormDD-mcp.exe'
Example requests

"Fill the leave form for John Smith, sick leave on 15 October" · "Make certificates with form CER1 for everyone in D:\class1.xlsx, one file per person" · "What forms does FormDD have?"

Privacy

What you type to the AI goes to that AI provider. Point it at an Excel file instead of pasting names into the chat: FormDD reads the file on your PC, and the row values are not sent to the AI.

What the AI can do

List forms, read a form's fields, fill one copy, and fill a batch — it cannot delete or edit templates. PDFs stay on your PC.
