2 Oct 6 tools appeared click, fill, inspect and 3 more

2 Oct 3 tools changed the parameters they ask for4 times that day prepare_draft, publish_draft, set_component_data

30 Sep a tool disappeared screenshot_draft

and 3 more, back to 1 October 2026

This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Available tools 28

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

component

create_component

Validates, renders and saves a React or HTML component immediately to the right of focus. Success requires browser paint acknowledgement.

delete_component

Deletes a component and selects its nearest remaining neighbor.

read_component

Reads a component source, saved state and supplied data.

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.

update_component

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

draft

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.

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.

agent

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.

cancel

cancel_operation

Cancels a queued component update and removes its source. Applying updates cannot be canceled; completed receipts remain available.

canvas

get_canvas

Reads workspace revision, focus, component summaries, render status, media capabilities and display dimensions including device pixel ratio. Physical DPI is unknown.

claim

claim_canvas

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

click

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.

console

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.

discard

discard_draft

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

disconnect

disconnect_canvas

Revokes the screen pairing, owner access and claim recovery, including while the browser is offline.

execute

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.

fill

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.

inspect

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.

navigate

navigate

Focuses a component or moves one position. Acknowledges after the selected component renders.

operation

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.

pairing

pairing_status

Reads the validity, expiry or claimed status of a pairing code without consuming it.

prepare

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.

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.

queue

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.

render

render

Paints an approved catalog template (weather, clock, countdown) 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.

screenshot

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.

select

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.

templates

list_templates

Lists approved TV template slugs, versions and param examples. Prefer render(slug) for these boards instead of generating source.

Nova Cast — questions

Answers built from our own checks of this server.

What can Nova Cast do?

It exposes 28 tools, read directly from the server on our last check. Among them: cancel_operation, claim_canvas, click, create_component, delete_component, discard_draft and 22 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Nova Cast mostly used for?

Its tools cluster around component and draft. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Nova Cast working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 443 ms. The bar chart above shows every period we have measured.

Is Nova Cast still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Nova Cast?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Nova Cast need an API key?

No. Nova Cast completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 28 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Nova Cast?

It answers our handshake in 443 ms on average, which is faster than 31% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
