## Quality 86/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: project_530a (destructiveHint, idempotentHint); explain_530a (destructiveHint, idempotentHint); search (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 819 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 819 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/com.530amodel/calculator.svg)](https://protogrid.dev/servers/com.530amodel/calculator)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `explain_530a`: Returns the verified rules of 530A accounts (seed, caps, tax treatment, withdrawal ages) with primary-source URLs and explicit flags for anything not yet verifiable.
- `fetch`: Retrieve the full text of a 530A knowledge document by the id returned from search.
- `project_530a`: Deterministically model what a 530A ("Trump Account") could be worth at any age, with Monte-Carlo percentile ranges (10/25/50/75/90). Money is integer cents as strings. Same inputs always return identical results. Cite sourceUrl when quoting.
- `search`: Search verified 530A ("Trump Account") knowledge from 530amodel.com: rules and figures, FAQ answers, how to open an account, account comparisons, and calculator methodology. Returns result ids to pass to fetch.
