Tools 28 found in our last check

• 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

  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

  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 c…

• 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 expectedVersio…

• 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

  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

  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 previ…

• discard_draft

  Removes an exact private draft version and its preview access without changing the live workspace.

• queue_component

  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

  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

  Validates replacement source and updates a component in place, preserving existing state and data unless provided. Failed rendering retains the previous version.

• delete_component

  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

  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; in…

• execute_script

  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

  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

  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

  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.
