Context Cost
~7,243Tokens (tool definitions)
~16.6 KBTypical response size
Significant attention impact (5.66% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢ai_api_cost(inputTokens, cachedInputTokens, outputTokens, requestsPerDay, requestsPerMonth, ...)
Estimate API workload costs in USD per request, day and month, with rates and dated snapshot provenance. Use for token budgets; use ai_subscription_stack_cost for chat or coding subscriptions. Model IDs use providerId/id from https://operatornest.com/api/models?subset=pricing, filtered to the MCP catalog; the OSS bundle lists accepted IDs in src/data/pricing-snapshot.json. Rates stay offline until the catalog is updated; missing rates return null. Cached tokens are part of total input; published batch and long-context rates apply only when eligible. Non-token charges are excluded.

}🟢meeting_time_zones(date, people)
Find shared 30-minute meeting slots inside 09:00–17:00 for 2–8 participants. Use to compare workday overlap; use recurring_schedule for repeating task calendars or cron_next_runs for scheduler previews. Returns all candidates, overlap count and up to three best slots ranked nearest to each person’s 13:00, with UTC starts and local labels. The date belongs to the first participant’s zone; daylight saving uses runtime IANA data. No calendar availability or holiday lookup, invitations or calendar writes.

}🟢recurring_schedule(startDate, tasks)
Prepare weekly, biweekly or monthly task calendars and estimate monthly effort for up to 20 tasks. Use to draft a recurring work plan; use cron_next_runs to preview existing cron syntax or meeting_time_zones for shared workday slots. Returns monthly hours, first dates, recurrence rules and an RFC 5545 calendar. Times float in the importing calendar’s local zone; weekly estimates use 52/12 runs per month and biweekly 26/12. owner is a planning label, with no assignment or execution. No calendar is updated; an empty task list returns zero hours and no events.

}🟢ai_subscription_stack_cost(planIds)
Total selected AI chat and coding subscriptions in USD and identify overlapping capabilities. Use to review a subscription stack; use ai_api_cost for API token charges. Select unique planIds from the schema enum; [] returns zero totals and no plans. Returns monthly and annual totals, selected plans, capability groups and dated official sources. Annual totals use published annual billing or twelve monthly charges; taxes, regional differences and promotions are excluded. Bundled rates are dated estimates, without live billing lookup or subscription changes.

}🟢cron_next_runs(expression, dialect, zone, after, count)
Preview up to 10 cron matches strictly after a supplied UTC instant, within a 366-day search. Use to check existing scheduler syntax; use recurring_schedule to draft task recurrence calendars or meeting_time_zones for participant overlap. Returns UTC starts, local labels, normalized inputs and a dated syntax source; fewer matches or [] means the search window ended. Supports numeric stars, lists, ranges, steps and weekday names in the selected dialect; rejects L, W, # and named months. cloudflare requires UTC; other zones follow runtime daylight saving transitions. No schedule is installed or run.
