Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

api

ai_api_cost

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.

cron

cron_next_runs

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.

meeting

meeting_time_zones

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

recurring_schedule

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.

subscription

ai_subscription_stack_cost

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.

Answers built from our own checks of this server.

What can OperatorNest tools do?

It exposes 5 tools, read directly from the server on our last check. Among them: ai_api_cost, ai_subscription_stack_cost, cron_next_runs, meeting_time_zones, recurring_schedule. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is OperatorNest tools working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 328 ms. The bar chart above shows every period we have measured.

How do I connect OperatorNest tools?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does OperatorNest tools need an API key?

No. OperatorNest tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is OperatorNest tools?

It answers our handshake in 328 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is OperatorNest tools open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at operatornest.com, which runs on its operator's own terms.
