CukaiMax for AI agents

CukaiMax gives ChatGPT, Codex, Claude, Gemini, Cursor, VS Code, GitHub Copilot, Kiro and any Streamable HTTP MCP client a source-linked Malaysian individual-tax authority layer.

The public server covers:

• YA2025 Form BE authority search and deterministic draft preparation.
• YA2025 Form B authority search and preparation-readiness checks for sole proprietors, freelancers, Grab drivers and e-commerce sellers.
• YA2026 source-verified planning changes, with filing fields blocked until HASiL publishes the official form and explanatory notes.

Endpoint: https://www.cukaimax.com/.well-known/mcp

No CukaiMax API key is required.

Example prompts

• Should I use Form B or Form BE for YA2025?
• What records should a Grab driver keep for deductible expenses?
• Which YA2025 Form B worksheets apply to an e-commerce seller?
• Check whether my fictional Form B example is ready for manual preparation.
• What is confirmed for YA2026, and what is still blocked pending HASiL forms?

Safety and privacy

The public MCP is read-only and stateless. Do not send taxpayer names, identification numbers, credentials, receipts or account data. No tool files or submits a return to MyTax. CukaiMax source verification is not official HASiL approval.
