## Quality 93/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 94 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 5,825 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

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

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

- tools: 8, about 5,825 tokens to load them all
- tool set hash: 7e4cf03e58865f4a0ea33353e1714dc5
- badge: [![protogrid quality](https://protogrid.dev/badge/tech.noahsarch/business-day-oracle.svg)](https://protogrid.dev/servers/tech.noahsarch/business-day-oracle)

## Tools (8)

- `add_working_days`: Move N working days from a date, skipping weekends and holidays; returns the end date and every skipped day with its reason. Delivery promises, SLA clocks, payment terms in business days. Example: start_date '2026-12-23', days 5, country 'DE', subdivision 'BY'. Calendar selection: country (ISO 3166-1 alpha-2, e.g. 'SA', 'DE', 'US') or market (MIC, e.g. 'XNYS', 'XLON'); optional subdivision (state/province/emirate code from list_calendars), categories (e.g. ['public','bank']), weekend override (['FRI','SAT']), extra_holidays (company/contract dates). Weekend defaults to the country's legal weekend. Response: result plus data_confidence (high = fixed-date calendar; medium = a lunar/moon-sighted or projected holiday is involved, or the caller overrode the weekend), estimated_items[] naming each projected date, sources[] (public references behind the calendar), data_version and warnings[].
- `compute_deadline`: Compute the end of a period ('within 30 calendar days', '10 working days', '3 months') from a start date under explicit counting rules, roll it by the chosen convention when it lands on a non-working day, and return raw vs final deadline, skipped days and a step-by-step explanation plus a disclaimer. Pass the rules the contract/law states; defaults are the common ones. Example: start_date '2026-11-26', period 7, unit 'calendar_days', country 'GB'. Calendar selection: country (ISO 3166-1 alpha-2, e.g. 'SA', 'DE', 'US') or market (MIC, e.g. 'XNYS', 'XLON'); optional subdivision (state/province/emirate code from list_calendars), categories (e.g. ['public','bank']), weekend override (['FRI','SAT']), extra_holidays (company/contract dates). Weekend defaults to the country's legal weekend. Response: result plus data_confidence (high = fixed-date calendar; medium = a lunar/moon-sighted or projected holiday is involved, or the caller overrode the weekend), estimated_items[] naming each projected date, sources[] (public references behind the calendar), data_version and warnings[].
- `is_working_day`: Say whether a date is a working day in a country/subdivision or market, and why not (weekend, holiday name, holiday observed, projected lunar holiday). Example: date '2027-03-10', country 'SA'.

Weekend defaults to the country's legal weekend. Response: result plus data_confidence (high = fixed-date calendar; medium = a lunar/moon-sighted or projected holiday is involved, or the caller overrode the weekend), estimated_items[] naming each projected date, sources[] (public references behind the calendar), data_version and warnings[].
- `list_calendars`: Discover calendars: without arguments, all 250 countries and 30 markets; with a country code, its legal weekend, subdivision codes, holiday categories, languages, year range and public sources. Free. Example: country 'US'. Response: result plus data_confidence (high = fixed-date calendar; medium = a lunar/moon-sighted or projected holiday is involved, or the caller overrode the weekend), estimated_items[] naming each projected date, sources[] (public references behind the calendar), data_version and warnings[].
- `list_holidays`: All holidays of a year for a country/subdivision/categories or a market, each with local and English names, whether it is observed/shifted, projected (lunar), on a weekend, and whether it counts as non-working. Example: year 2027, country 'IN', subdivision 'KA'. Calendar selection: country (ISO 3166-1 alpha-2, e.g. 'SA', 'DE', 'US') or market (MIC, e.g. 'XNYS', 'XLON'); optional subdivision (state/province/emirate code from list_calendars), categories (e.g. ['public','bank']), weekend override (['FRI','SAT']), extra_holidays (company/contract dates).
