How to connect

How to connect Nova Cast to Claude

The server address to paste into Claude settings:

https://nova.ardabot.ai/mcp

Open Claude (claude.ai or the desktop app).
Go to Settings → Connectors.
Click Add custom connector.
Paste the server address copied below into Remote MCP server URL and click Add.
In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect Nova Cast to ChatGPT

The server address to paste into ChatGPT settings:

https://nova.ardabot.ai/mcp

Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
Open Settings → Connectors and click Create.
Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

Server tool list (28)

Raw names from tools/list. Only developers need these.

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 changes stage a private draft (previewRequired) and leave live untouched. Data-only refreshes need componentID.
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 density, dead space, readable icons/temps, clipped content and broken panels, then publish_draft. Never put previewURL in chat.
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 previous component.
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; inactive components acknowledge saved data only.
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.
