530A Model
530amodel.com — a free, privacy-first, mobile-first scenario-planning calculator for 530A custodial retirement accounts ("Trump Accounts").
No login. No email capture. No monetization. All calculation runs in your browser.
Use the public API / MCP server
The engine is free to call — no key, nothing stored, attribution to 530amodel.com asked:
- JSON API —
https://api.530amodel.com(POST /v1/project,GET /v1/rules,GET /v1/returns; OpenAPI 3.1 with full request/response schemas) - MCP server —
https://mcp.530amodel.com(streamable HTTP; toolsproject_530a,explain_530a,search,fetch; registry namecom.530amodel/calculator). Works as a custom connector in Claude and ChatGPT, and with the Anthropic/OpenAI agent APIs. - Docs & platform quickstarts — 530amodel.com/api · machine-readable maps: llms.txt, llms-full.txt

Non-negotiables
- Financial math is exact, deterministic, and independently tested (golden vectors from the Python reference implementation must match the TS engine to the cent).
- Static-first: calculation is client-side; a million users cost the same as one.
- Minimal dependencies, no PII, small attack surface, everything scanned in CI.
- Every user-facing claim is honest: ranges are labeled estimates, legal figures cite sources,
unverified items live behind OFF feature flags (
packages/config/src/flags.ts).
Development
pnpm install
pnpm check # lint + typecheck + test + build (same as CI)
pnpm --filter @530a/web dev
Node ≥ 22, pnpm ≥ 11. Engine numeric contract: money is integer cents (bigint), balances are
quantized round-half-to-even every monthly step, display formatting only via formatMoney.
