CukaiMax Malaysian Tax Authority

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.

VS Code / GitHub Copilot

code --add-mcp '{"name":"cukaimax-tax-authority","type":"http","url":"https://www.cukaimax.com/.well-known/mcp"}'

Cursor

Use the one-click installer on cukaimax.com/install-agent, or merge:

{
  "mcpServers": {
    "cukaimax-tax-authority": {
      "type": "http",
      "url": "https://www.cukaimax.com/.well-known/mcp"
    }
  }
}

Kiro

Open the Powers panel, choose Add Custom Power → Import power from GitHub, and install:

https://github.com/jakzaizzat/cukaimax-agent

Kiro loads the portable skill and manages the remote MCP connection from the Agent Plugins manifests.

Smithery

Discover, inspect, and connect the same hosted MCP through the CukaiMax Smithery listing. Smithery has indexed all five read-only tools and eight public resources. The official registry release is also indexed as a hosted connector on Glama and as an open-source server at glama.ai/mcp/servers/jakzaizzat/cukaimax-agent. This repository includes a stdio catalog adapter (npm start) so Glama can start the process and run initialize / tools/list. Production clients should keep using the hosted Streamable HTTP endpoint.

Agent Skills registry

Install the indexed CukaiMax skill through the portable Agent Skills CLI:

npx skills add jakzaizzat/cukaimax-agent --skill cukaimax-tax-authority

The public listing is available on skills.sh.

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.
