Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Use this server for source-linked Malaysian individual tax rules. YA2025 Form BE is source-verified by CukaiMax and supports deterministic drafts; YA2025 Form B is source-verified for authority search and preparation-readiness checks, not calculation; YA2026 contains source-verified planning changes but no return fields until official forms exist. Every tool result includes a privacy-safe audit event with immutable release, rule, and source references. Pass the returned event ID into the next audit context to create a replayable chain. Source verification is not official HASiL approval and output is never filed or submitted to MyTax.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http cukaimax-mcp https://www.cukaimax.com/.well-known/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add cukaimax-mcp --url https://www.cukaimax.com/.well-known/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cukaimax-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "cukaimax-mcp": {
      "url": "https://www.cukaimax.com/.well-known/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

  "mcpServers": {
    "cukaimax-mcp": {
      "type": "streamableHttp",

Gemini CLI configuration
gemini mcp add --transport http cukaimax-mcp https://www.cukaimax.com/.well-known/mcp

Claude Desktop
