Context Cost

~6,906Tokens (tool definitions)
~2.1 KBTypical response size
Significant attention impact (5.40% 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.

⚪claim_canvas(code, claimKey)

Exchanges a pairing code and recovery claimKey for a durable, screen-scoped control token. Repeating the same pair recovers the original grant.

🔴render(operationID, expectedRevision, slug, componentID, params, ...)

Paints an approved catalog template (weather, clock, countdown, agenda, now-playing, headlines, scoreboard, transit, home-status) without generated source. weather location defaults to Sudbury. First matching-display paint skips preview. Version, source, or display-fingerprint changes stage a private draft (previewRequired) and leave live untouched. Data-only refreshes need componentID.

🟡prepare_draft(operationID, expectedRevision, title, format, source, ...)

Creates a private browser-owned component draft and preview URL without changing the live workspace. Drafts expire after 15 minutes or browser reload. Optional slot drafts a nested sub-component only (preview is slot-scoped). Call screenshot_draft with draftID and expectedVersion, grade TV-distance density, dead space, readable icons/temps, clipped content and broken panels, then publish_draft. Never put previewURL in chat.

🟢read_draft(draftID, controlToken)

Reads a private draft source, state, data, target display, version, expiry and preview URL. Requires the original canvas online. Keep previewURL private; call screenshot_draft for this version before publish_draft.

Input Schema

  "type": "object",
  "properties": {

}
🟢screenshot_draft(draftID, expectedVersion, controlToken)

Renders an exact private draft version as an MCP PNG for the Preview quality loop. Requires draftID and expectedVersion. Isolated layout only — not the live TV. A screenshot never publishes.

}
🔴update_draft(operationID, expectedRevision, title, format, source, ...)

Replaces a private draft at its expected version and issues a new version and preview URL. Previous preview links become invalid; original expiry is unchanged. Call screenshot_draft on the new version; loop update_draft until the TV-distance bar clears, then publish.

🔴publish_draft(operationID, expectedRevision, draftID, version, review, ...)

Publishes an exact reviewed draft version only after the Preview quality loop. Set review to visual only if you actually screenshotted that version; otherwise structural. Do not publish a failing layout. Success requires ok and receipt:paint. Failed rendering preserves the previous component.
