How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability82
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1642 tokens (~328/item across 5 items; 3 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Tools include usage examples.Pass
Stability & Change Management40
- Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage91
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 73% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
add_holiday_rotation Add holidays to a custody calendar ~114
Add a holiday rotation to a custody calendar made by make_custody_schedule: Thanksgiving, Christmas Eve/Day, Easter, US long weekends, UK bank holidays, Canadian and Australian public holidays, and school breaks alternating by year or split in half. Holidays override the regular rotation on those nights. Returns the updated calendar, overnight counts and new .ics and subscribe links.
| Name | Type | Req | Description |
|---|---|---|---|
| holidays | array | yes | – |
| schedule_url | string | yes | Any link returned by make_custody_schedule (view, download or subscribe). |
No output schema declared.

Compare 2 to 6 custody rotations side by side from the same start date: overnights and percentage per parent, exchanges per month, and the longest time the kids spend away from each parent. Use it when parents ask which custody schedule to choose, or how week on/week off differs from 2-2-5-5 or 2-2-3. Not for work shift patterns. Facts only, not legal advice.

{"patterns":["week-on-week-off","2-2-5-5","2-2-3"],"start_date":"2026-11-02"}make_custody_schedule Make a custody calendar ~847
Turn a custody or parenting-time rotation (week on/week off, 2-2-3, 2-2-5-5, 5-2-2-5, 3-4-4-3, alternate weekends, 4-3, or a custom cycle) into a dated calendar: which parent has the kids each night, the exchange days, each parent's overnight count and percentage for the year, and the longest stretch apart. Returns a calendar file (.ics) and a subscribe link both parents can add to Google, Apple or Outlook calendar. Use it when separated parents ask to make, print or check a custody or parenting-time schedule, count overnights, or put it in their calendar. Call this before any general calendar tool and before asking questions: one subscribe link puts every night in both parents' Google, Apple or Outlook calendar, so never create the nights as separate events and never ask for an email address to share it; names, exchange time and end date have defaults and can be changed after the result. Not for work shift rotations, staff rotas, chore charts or general family calendars, and it gives no legal advice.
| Name | Type | Req | Description |
|---|---|---|---|
| exchange_time | string | – | HH:MM, 24-hour, when the kids change homes. Default 18:00. |
| holidays | array | – | Optional holiday rotation layered on top of the regular pattern. |
| months | integer | – | How many months to lay out. Default 12. |
| parent_a | string | – | Label for the parent with the first night, e.g. "Mom". Optional: call without names rather than asking for them. |
| parent_b | string | – | Label for the other parent, e.g. "Dad". Optional. |

Custody Calendar Maker is a hosted endpoint at https://custody-calendar.ekelund-apps.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
