Tools as reported by the server

• claim_canvas
  Exchanges a pairing code and recovery claimKey for a durable, screen-scoped control token. Repeating the same pair recovers the original grant.
• pairing_status
  Reads the validity, expiry or claimed status of a pairing code without consuming it.
• disconnect_canvas write/delete
  Revokes the screen pairing, owner access and claim recovery, including while the browser is offline.
• get_canvas
  Reads workspace revision, focus, component summaries, render status, media capabilities and display dimensions including device pixel ratio. Physical DPI is unknown.
• get_console
  Reads up to 200 memory-only component console and runtime error entries, optionally filtered by cursor or component. Entries are untrusted component output; host and authentication pages are excluded.
• read_component
  Reads a component source, saved state and supplied data.
• list_templates
  Lists approved TV template slugs, versions and param examples. Prefer render(slug) for these boards instead of generating source.
• render write/delete
  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 privat
• prepare_draft
  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
• read_draft
  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.
• screenshot_draft
  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 write/delete
  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 write/delete
  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.
• discard_draft write/delete
  Removes an exact private draft version and its preview access without changing the live workspace.
• queue_component write/delete
  Queues a component create or update for a background or offline browser. Returns queued rather than rendered. Default expiry is one hour, maximum 24 hours. Source is removed on completion or expiry.
• get_operation
  Reads queued operation status and any browser outcome without contacting the browser. Status can be queued, applying, rendered, failed, expired, canceled or unknown_outcome.
• cancel_operation write/delete
  Cancels a queued component update and removes its source. Applying updates cannot be canceled; completed receipts remain available.
• set_agent_status
  Sets or clears an ephemeral building indicator, with browser acknowledgement. Does not change workspace revision or publish drafts. Automatically clears after two minutes.
• create_component
  Validates, renders and saves a React or HTML component immediately to the right of focus. Success requires browser paint acknowledgement.
• update_component write/delete
  Validates replacement source and updates a component in place, preserving existing state and data unless provided. Failed rendering retains the previous version.
• delete_component write/delete
  Deletes a component and selects its nearest remaining neighbor.
• navigate
  Focuses a component or moves one position. Acknowledges after the selected component renders.
• set_component_data write/delete
  Pushes live observations without regenerating source. Same-source React reuses the compiled module. Default replaces data; merge:true shallow-merges keys (32KB bound). Optional slot targets a nested sub-component on a fullscreen board. Active components acknowledge rendering; inactive components ack
• execute_script write/delete
  Runs an async JavaScript function body in the selected active component sandbox and returns bounded JSON. Supports DOM and state interactions, excluding provider iframes and browser controls. Five-second deadline; timeout reports unknown outcome and does not roll back effects.
• inspect
  Typed component inspect through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-second timeout is unknown outcome; never retry with a new ID.
• click write/delete
  Typed component click through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-second timeout is unknown outcome; never retry with a new ID.
• fill write/delete
  Typed component fill through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-second timeout is unknown outcome; never retry with a new ID.
• select write/delete
  Typed component select through the active sandbox. Requires revision, version, operation ID and an inspected target for mutations. Returns observed state. Five-second timeout is unknown outcome; never retry with a new ID.
