CLI

The astro-slides CLI drives every stage of a deck’s life: developing, building, exporting, and serving the MCP server. Run it through pnpm (pnpm astro-slides <command>) or via the bin if the package is installed globally.

astro-slides <command> [root] [flags]

Every command takes an optional positional root — the project directory. It defaults to the current working directory.

dev

Start the Astro dev server and watch the deck. Hot reload is scoped per slide.

astro-slides dev [root] [--remote[=<password>]]

Flag	Description
--remote	Bind to 0.0.0.0 and stand up the mobile-remote sync gateway. The URL is open on your LAN — anyone with it can drive the deck.
--remote=<password>	Same, but derives an access token from the password so only holders of the tokenized URL can connect.

With --remote, the CLI prints a QR code and the /entry URL a phone opens to become a touch remote.

In-TTY shortcuts

While dev is running in an interactive terminal, single keypresses trigger actions. Press ? to reprint the list.

Key	Action
r	restart the dev server
o	open the deck in your browser
e	open the deck source in your editor
c	clear the console
m	toggle the MCP server
q	quit
?	show the shortcut list

Ctrl+C also quits.

build

Build the deck to static output via Astro’s build. Produces a dist/ directory you can host anywhere (GitHub Pages, Netlify, etc.).

astro-slides build [root]

export

Build the deck, start a preview server, and drive headless Chromium to render an export. Supports PDF, PNG, editable PPTX, and an offline HTML bundle.

astro-slides export [root] --format <pdf|png|pptx|html> [flags]

Playwright required

Export drives Chromium through Playwright. Install it first:

pnpm add -D @playwright/test
pnpm exec playwright install chromium

Flag	Default	Description
--format <fmt>	pdf	Output format: pdf, png, pptx, or html.
--output <path>	per-format	Output file or directory (see below).
--range <spec>	all slides	Subset of slides to include, e.g. "1,3-5,8".
--per-slide	false	PDF: write one file per slide instead of one combined document.
--with-clicks	false	PNG: emit one image per click step, not just per slide.
--with-toc	false	PDF: add a document outline (bookmarks) from slide titles.
--rasterize	false	PPTX: rasterize every slide to a full-slide image instead of extracting editable shapes.
--dark	false	Force the dark color scheme.
--scale <n>	PNG DPR 2	Render scale — PNG device-pixel-ratio / PDF page scale.
--omit-background	false	PNG: transparent background.
--executable-path <path>	bundled	Use a custom Chromium binary.

Output paths. When --output is omitted, PDF writes <deck>.pdf, PPTX writes <deck>.pptx, PNG writes into a <deck>-png/ directory, and HTML writes dist.zip. For --per-slide PDF the --output value is treated as a directory.

# Combined PDF of the whole deck
astro-slides export --format pdf --output talk.pdf

# One PNG per slide, only slides 1, 3-5 and 8, at 3x DPR
astro-slides export --format png --range "1,3-5,8" --scale 3

# Editable PowerPoint
astro-slides export --format pptx --output talk.pptx

# Offline HTML bundle (zipped dist/)
astro-slides export --format html --output talk.zip

--range syntax

A range spec is a comma-separated list of 1-based slide numbers and from-to ranges: "1,3-5,8" selects slides 1, 3, 4, 5, and 8. Values are sorted, deduped, and clamped to the deck’s bounds; reversed ranges (5-3) are normalized.

mcp-server

Run the astro-slides MCP server so an MCP-aware client (Claude Code, Cursor, Windsurf, custom agents) can read, write, navigate, and export decks. Defaults to stdio transport; use --transport http for Streamable HTTP.

astro-slides mcp-server [root] [--transport <stdio|http>] [flags]

Flag	Default	Description
--transport <t>	stdio	Transport: stdio or http (Streamable HTTP).
--host <ip>	127.0.0.1	Bind host (HTTP only).
--port <n>	4444	Port (HTTP only).
--token <secret>	—	Bearer token. Also read from ASTRO_SLIDES_MCP_TOKEN. Required for HTTP over a non-loopback host.
--read-only	false	Disable the write tools (read/navigate/export only).
--sync-gateway <url>	—	URL of a running dev sync gateway, so navigate tools can drive a live deck.
--sync-token <token>	—	Token for the sync gateway.

# stdio (for a local agent that spawns the process)
astro-slides mcp-server

# HTTP with a bearer token
astro-slides mcp-server --transport http --port 4444 --token "$(openssl rand -hex 16)"

Tokens over the network

When serving HTTP on a non-loopback host, a token is required. Pass it with --token or set ASTRO_SLIDES_MCP_TOKEN. Use --read-only to expose a server that cannot modify deck source.
