Malaysian SME accounting, e-Invoice and payroll — with an MCP server your AI works through. 51 tools: your AI reads the live books (P&L, balance sheet with server-computed period comparison, agings, cash and tax position), drafts every document type including adjusting journals, proposes bank classifications, stages a whole migration (chart of accounts, contacts, products, opening balances, historical documents) and even the workspace setup — and checks its own queue: what it filed, what you approved, what you rejected and why.
