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 →

Tool Tokens
skylight_update_chore ~275

Update a chore. apply_to 'this_and_future' or '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 recurring chores: which occurrences to update.

No examples provided.

skylight_update_event ~398

Update a calendar event by id. 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.

all_dayboolean––
category_idsarray–Family-member category ids to assign the event to (see skylight_list_categories / skylight_resolve_member).

No output schema declared.

skylight_update_frame ~269

Update Skylight frame display/sleep settings. Setting open_to_public:true makes the frame publicly reachable, so that one change 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). Every other setting applies directly.

skylight_update_meal ~545

Update a planned meal (meal sitting) — change its name, recipe, category/slot, notes, date or repeat rule. Targets one occurrence by its date and applies the change at the chosen recurrence scope. For a one-time meal omit apply_to. For a recurring meal, note that apply_to:'one' and 'future' SPLIT the series into additional sittings rather than editing in place; re-run skylight_list_meals afterward to see the resulting shape. 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 and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).

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…

notestring––
rrulestring–Replacement iCal RRULE string (plain string, NOT an array).

skylight_upload_photo ~336

Upload a photo or video from a local file to the Skylight frame (it appears in the slideshow). Two-step: signs an S3 upload with temporary credentials, then registers it as a frame message. 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 echoes the resolved absolute image_path, detected mime, size and caption, and nothing is read or uploaded until it is confirmed.

NameTypeReqDescription
captionstring–Caption shown with the photo.
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…

Common questions

What is the io.github.chrischall/skylight-mcp server?

io.github.chrischall/skylight-mcp is listed in the public MCP registry as io.github.chrischall/skylight-mcp. Skylight Calendar for Claude, family events, chores, and rewards. This page covers its npm package (skylight-mcp).

Is the io.github.chrischall/skylight-mcp server safe to use?

io.github.chrischall/skylight-mcp scores 93 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.chrischall/skylight-mcp server expose?

io.github.chrischall/skylight-mcp exposes 114 tools: skylight_list_frames, skylight_get_frame, skylight_list_frame_members, skylight_list_devices, skylight_get_plus_access, and 109 more. Their descriptions and schemas cost roughly 11,112 tokens of context every time the server is loaded.

Is the io.github.chrischall/skylight-mcp server still maintained?

io.github.chrischall/skylight-mcp is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the io.github.chrischall/skylight-mcp server under?

io.github.chrischall/skylight-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

What did VerifyMCP test on the io.github.chrischall/skylight-mcp server?

VerifyMCP ran 16 checks on io.github.chrischall/skylight-mcp, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
