Scored across 14 tools
Most tools target clearly distinct reference or calculation tasks, such as HTTP status lookup, MIME lookup, time conversion, and duration arithmetic. There is some overlap between http_status and retry_advice on retryability, and between describe_instant, unix_time, and weekday_of on date/timestamp details, but descriptions generally steer selection well.
All tool names use lower snake_case, which is consistent and readable. However, the set mixes verb_noun names like add_duration and list_mime_types with noun phrases like http_status, mime_type, and time_until, so the convention is not uniformly verb-based.
The server has 14 tools, which is within a reasonable range for a reference and utility server covering HTTP, MIME, and time/date concerns. Each tool appears to represent a distinct lookup or calculation operation rather than an arbitrary expansion.
The surface covers common web/API reference needs including HTTP methods, status codes, retry guidance, MIME types, content-type checking, and time/duration calculations. Minor gaps exist, such as broader timezone handling or HTTP header reference, but the main workflows are supported.
Available Tools
14 toolsadd_durationAInspect
Add a duration to an instant and get the result, in UTC and in Tehran local time. Use it for a TTL, a lock expiry, or a token lifetime. ($0.003 per call)
Inputs: at (required), amount (required), unit.
business_days_betweenAInspect
Count the business days between two dates, excluding weekends. Use it to turn a calendar deadline into a working-day deadline. Public holidays are not excluded, so the count is an upper bound. ($0.005 per call)
Inputs: to (required), from (required).
content_type_adviceAInspect
Check whether a Content-Type header matches what an endpoint kind expects, and say what to send instead when it does not. ($0.003 per call)
Inputs: contentType (required), endpointKind (required).
convert_durationAInspect
Convert a duration between units and get it in plain language. Use it to express a timeout in the unit the caller asked for, or to check whether a limit is seconds, minutes or milliseconds. ($0.003 per call)
Inputs: value (required), to, from.
describe_instantAInspect
Describe an instant: its date, weekday and time in UTC and in Tehran local time (UTC+03:30), plus the Unix timestamp. Use it when a response carries a timestamp and the local date matters. ($0.003 per call)
Inputs: at (required), timezone.
http_methodAInspect
Describe an HTTP method: whether it is safe, whether it is idempotent, whether it carries a body, and what it is for. ($0.003 per call)
Inputs: method (required).
http_statusAInspect
Look up an HTTP status code: what it means, what the client must do, whether it is retryable, whether it is safe to replay, the defining RFC and the common causes. ($0.003 per call)
Inputs: code (required), detail.
list_mime_typesBInspect
List or search MIME types by top-level type or by keyword, for example image types or anything to do with calendars. ($0.003 per call)
Inputs: limit, query, topLevel.
mime_typeAInspect
Look up a MIME type by full type or by file extension: the top-level type, what it is for, and the usual file extension. ($0.003 per call)
Inputs: type, extension.
retry_adviceAInspect
Decide how a client should react to a status code: retry with backoff, check the outcome before retrying, or do not retry. Includes a suggested backoff schedule. ($0.005 per call)
Inputs: code (required), idempotent.
status_for_situationAInspect
Find the HTTP status code that matches a described situation, when the code is not known in advance — for example 'the caller is being rate limited' or 'upstream returned garbage'. ($0.005 per call)
Inputs: situation (required).
time_untilAInspect
How much time is between two instants: the direction, the total in every unit, and a day/hour/minute/second breakdown. Use it to compute a retry delay, a rate-limit reset, or whether a deadline has passed. ($0.003 per call)
Inputs: to (required), from (required).
unix_timeAInspect
Convert between a date and a Unix timestamp, in either direction. Use it when a payload carries one and the other is needed. ($0.003 per call)
Inputs: date, timestamp.
weekday_ofAInspect
Which day of the week a date falls on, and whether it is a business day. Use it before scheduling work or setting a deadline that lands on a weekend. ($0.003 per call)
Inputs: date (required), weekStartsOn.
