Install NULA.BG in Claude Code, Cursor or VS Code

Runs npx -y nulabg-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the NULA.BG repository's README, as published. We do not edit it. Read it on GitHub

nulabg-mcp

MCP сървър за счетоводната платформа nula.bg. Дава на Claude и на други AI асистенти (Claude Desktop, Claude Code, Cursor, VS Code…) достъп до вашите фактури, покупки, OCR, клиенти, склад и банки чрез nula.bg API ключ.

Неофициален клиент. Проектът не е свързан с nula.bg. Работи върху публичното им REST API.

🇬🇧 In English: an MCP server for nula.bg, a Bulgarian cloud accounting platform — invoices, bills with OCR, customers, inventory, bank feeds and derived reports, over an API key. Read-only by default. Install the .mcpb bundle in Claude Desktop, or run npx -y nulabg-mcp with NULAAPIKEY set. The rest of this README is in Bulgarian, because the platform, its documents and its users are; the tool descriptions the model sees are in English. Issues and pull requests in either language are welcome.

Какво може

21 tools при разрешени промени, 13 в режим само за четене (по подразбиране), 25 с включени nra и noi. При няколко фирми се появява и nulalistcompanies.

Освен това има:

  • Prompts: issue-invoice, process-receipts, month-end-review, collect-overdue.
  • Resources: основанията за 0% ДДС, основанията за протоколи, всички стойности на enum-ите и PDF на фактура.

Примерни заявки:

  • „Издай фактура на ЕИК 123456789 за 10 часа консултации по 60 € без ДДС, платима по банка до 15 дни.“
  • „Качи всички PDF-и от ~/Documents/Фактури/Септември като покупки и ми покажи какво е разпознато.“
  • „Кои клиенти ми дължат пари от над 30 дни?“
  • „Сравни входящите плащания по банковата сметка за септември с неплатените фактури.“

Инсталация

Нужен е API ключ от nula.bg, генериран от вашия акаунт в nula.bg. Ключът дава достъп до данните на фирмата, затова го пазете като парола.

🔒 По подразбиране сървърът е само за четене. Claude може да търси и чете, но не може да създава, редактира, изпраща или трие нищо в nula.bg. Така тестването и оценката са безопасни. За да разрешите промени, задайте NULAREADONLY=false (в Claude Desktop: махнете отметката „Само четене“ в настройките на разширението).

Claude Desktop (препоръчително)
