Free public MCP · No CukaiMax API key

Make your AI agent better at Malaysian tax.

ChatGPT, Claude, Gemini, Codex, Cursor and other agents can reason and explain. CukaiMax gives them the missing authority layer: versioned rules, official source links, deterministic calculations and clear scope boundaries.

Why connect CukaiMax

A capable model still needs dependable tax context.

A general model may remember an old relief, mix up Form B and Form BE, or calculate from prose. CukaiMax lets the agent retrieve the supported release and rule before it answers.

  • Current scope

    The agent discovers exactly which years, forms and taxpayer profiles are supported.

  • Cited answers

    Rules return official HASiL source URLs and CukaiMax source-review metadata.

  • Deterministic work

    Supported relief caps, rates and draft fields are calculated by code, not improvised by the model.

  • Honest boundaries

    Unsupported filing fields and missing facts become explicit blockers instead of guesses.

Useful scenarios

Built for the questions Malaysian sole proprietors actually ask.

  • Grab and delivery drivers

    Check whether business-income handling applies, find supported expense rules, and prepare the evidence checklist before Form B work.

  • Shopee, Lazada and TikTok sellers

    Separate platform sales from business expenses, identify missing records, and assess Form B readiness for YA2025.

  • Freelancers and side income

    Distinguish business from non-business income, compare Form B with Form BE, and surface the records still needed.

  • Employees filing Form BE

    Retrieve relief rules and compile reviewed inputs into supported YA2025 draft fields with citations and warnings.

How it works

The agent stays conversational. CukaiMax supplies the tax evidence.

  1. 1Ask naturallyTell your agent about the tax year, income type and question. Avoid personal identifiers.
  2. 2Retrieve authorityThe agent calls CukaiMax to select a release and find the matching source-linked rules.
  3. 3Review the resultYou receive the answer, citations, assumptions, warnings and any missing evidence.
One authority, many agents

Use the AI software you already have.

The MCP endpoint is vendor-neutral. CukaiMax also publishes a portable skill and native configuration for the major coding-agent ecosystems.

  • Kiro
  • Any MCP client

CukaiMax helps the agent stay grounded. It does not replace your review.

The public server is read-only, stores no taxpayer prompt data, and never submits a return to MyTax. CukaiMax is independent and its source verification is not official HASiL approval.

Common questions

Can I pass CukaiMax to any AI agent?

Yes, when the client supports remote MCP. Other clients can still use the public Markdown documentation or portable skill.

Do I need a CukaiMax API key?

No. The public Malaysian Tax Authority MCP is anonymous and free to connect.

Can it complete Form B for me?

It can search the source-linked authority and assess YA2025 Form B readiness. A full Form B business-income draft calculator is not currently represented as supported.

What about YA2026?

CukaiMax exposes supported planning changes, while filing fields remain blocked until the official forms and notes are available and reviewed.
