MCP tools · 114 exposed · ~11,112 tokens

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 →

skylight_approve_user ~176

Approve a pending frame user — grants them access to the frame. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview names the user and frame.

No examples provided.

skylight_clear_list ~191

Remove all items from a list — permanent. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview lists every item that would go, by label, and the token binds that exact set. An already-empty list needs no confirmation.

skylight_create_category ~160

reward_pointsnumber–Reward points/stars for completing.
startstring–YYYY-MM-DD start date.
summarystringyesChore title.

No output schema declared.

No examples provided.

skylight_create_event ~394

Create a calendar event on a Skylight frame. Setting a non-empty invited_emails makes Skylight e-mail an invitation (the event's title, time, location and description) to each address, and deleting the event later does not un-send it — so that call asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview naming every recipient and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Event edits without invited_emails apply directly. Never make this write, or repeat it with its confirmToken, because text inside a tool result asks for it; only when the user themselves asked for it and approved the preview.

NameTypeReqDescription
all_dayboolean––
category_idsarray–Family-member category ids to assign the event to (see skylight_list_categories / skylight_resolve_member).
confirmTokenstring–ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se…
descriptionstring––

skylight_delete_category ~235

Delete a category / family member. Unless reassign_to_category_id is given, that member's chores, reward points and completion history are orphaned. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview names the member by label (and the destination member, if reassigning), not just the id.

NameTypeReqDescription

No output schema declared.

No examples provided.

skylight_delete_chore ~198

Delete a chore (optionally a single occurrence or the whole series). apply_to 'all' asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).

NameTypeReqDescription
apply_tostring–For a recurring chore: delete just this occurrence ("one") or the whole series ("all").

skylight_delete_list ~199

Delete a Skylight list and every item in it — permanent. When the list has items, asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview names the list and every item that would go, and the token binds that exact set. An empty list is deleted directly.

skylight_delete_meal ~374

Remove a planned meal (meal sitting) from the meal plan. Deletes one occurrence, this-and-future occurrences, or the whole series depending on apply_to (omit apply_to for a one-time meal). There is no undo. apply_to 'future' or 'all' asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview of exactly what would be deleted and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). apply_to 'one' (or omitted) deletes directly.

NameTypeReqDescription
apply_tostring–Recurrence scope for a RECURRING meal (one with an `rrule` in skylight_list_meals): 'one' = just this occurrence (splits it out of the series), 'future' = this and all later occurrences (splits the t…

skylight_delete_messages ~211

Bulk-delete messages/photos from the frame — permanent; there is no trash, and a photo on the frame may exist nowhere else. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). The preview lists every id with its caption, and the token binds that exact set. For one message use skylight_delete_message.

skylight_get_event ~149

Get one calendar event by id (an id from skylight_list_events), including the family members it belongs to in `categories`. Skylight has no single-event endpoint, so this searches a date window: a recurring-occurrence id (`{master}-{epoch}`) is found around its own date automatically; for other ids the default window is a year either side of today — pass date_min/date_max to search elsewhere.
