InfoSlides — put content on a TV or screen

InfoSlides: put content on a TV from your terminal or your agent

Turn a PowerPoint, a PDF, a photo, or a live data feed into a video stream playing on any smart TV. The lunch menu on the screen in reception. Opening hours in a shop window. A noticeboard in a school corridor. Room information in a hotel lobby. A live numbers board in an office.

This repo is the infoslides binary: one dependency-free executable that is both a developer CLI and an [MCP](https://modelcontextprotocol.io) server for AI agents like Claude Code, Claude Desktop, and Cursor. The same tools also run as a hosted server at https://infoslides.app/mcp, for assistants like ChatGPT and Claude on the web (see Hosted server).

The interesting part is that create_tenant is anonymous. An agent with this server installed can take someone from *no account at all* to content playing on a physical screen: provision the workspace, upload the deck, register the display, assign the schedule, hand back the stream link, without anyone opening a dashboard. As far as we know, no other digital signage platform can be driven that way.

New workspaces land on a permanent free plan: 1 screen, 4 slideshows, 2 users, 200 MB. No credit card, no trial clock, nothing expires. The whole flow below costs nothing and keeps running.

Zero to a live screen

# 1. Install (macOS/Linux; see Install for Windows and MCP clients)

Version-pinned. Check /releases/latest for the current one.

Download, check the file against the release's checksums, and only then unpack it.

curl -LO https://github.com/arnibj/InfoSlides.MCP/releases/download/v1.9.0/infoslides-v1.9.0-linux-x64.tar.gz curl -LO https://github.com/arnibj/InfoSlides.MCP/releases/download/v1.9.0/sha256sums.txt sha256sum -c --ignore-missing sha256sums.txt && tar xzf infoslides-v1.9.0-linux-x64.tar.gz

2. Create a workspace (anonymous; prints an admin API key and saves it to ~/.infoslides)

./infoslides tenant create "Acme Cafe" owner@acme.test --save

3. Grab a ready-made deck from the starter gallery

./infoslides gallery list ./infoslides slideshow clone --from-gallery

4. Register the screen and tell it what to play

./infoslides device create "Reception TV" ./infoslides schedule assign

5. The link to open on the TV

./infoslides stream link

Open that URL in the TV's browser or the InfoSlides TV app. It plays the content whichever way this screen is set up to play it.

As an MCP server

Hook it into an MCP client:

infoslides mcp install --client claude-code      # or claude-desktop / cursor

Or install as a Gemini CLI extension or Antigravity plugin:

# In Gemini CLI

gemini extensions install https://github.com/arnibj/InfoSlides.MCP

In Antigravity CLI (install agy first, see below), from a clone of this repository

git clone https://github.com/arnibj/InfoSlides.MCP agy plugin install ./InfoSlides.MCP

Antigravity installs plugins from a folder, so it needs a copy of this repository; the repository root is the plugin (plugin.json, mcp_config.json and skills/). Install agy itself first: irm https://antigravity.google/cli/install.ps1 | iex on Windows, or curl -fsSL https://antigravity.google/cli/install.sh | bash on macOS and Linux. Both routes run the local infoslides program, so install that first and put it on your PATH. (agy plugin import gemini only imports extensions already installed in Gemini CLI and takes no URL.)

Or add the Claude plugin (it uses the hosted server, nothing to install first):

claude plugin marketplace add arnibj/InfoSlides.MCP

claude plugin install infoslides@infoslides

Or install the .mcpb bundle from the latest release in any client that supports MCP bundles. It carries binaries for all three platforms and needs no runtime and no API key to get started.

Or configure it by hand (stdio transport):

{

"mcpServers": { "infoslides": { "command": "/path/to/infoslides", "args": ["--mcp"], "env": { "INFOSLIDES_API_KEY": "isk_admin_..." } } } }

INFOSLIDES_API_KEY is optional. Leave it out and the agent can create a workspace from scratch.

Hosted server

Assistants that run in the browser or the cloud connect to the hosted server instead of a local binary:

https://infoslides.app/mcp

• Transport: streamable HTTP.
• Sign-in: OAuth with your InfoSlides account. The assistant opens an InfoSlides consent page, you approve it, and it acts as you in that workspace. A bearer isk_ API key also works.
• Where to add it: as a custom connector in ChatGPT, Claude or Gemini, or through the Claude plugin above.
• Disconnecting: revoke any connection at infoslides.app/settings/connected-apps.

For ChatGPT, Claude and other hosted assistants the server offers a curated set of tools for everyday screen work (a Gemini connection gets a wider set): what is playing, slides, schedules, tickers, live data, devices and AI Studio slides. It leaves out billing and checkout, workspace creation, API key management and file uploads from a local path, which only make sense on your own machine or in the dashboard. Every call goes to the InfoSlides API with your own credential, and the server stores none. It loads the hosted variant of the assistant skill (zip).

What the agent gets

The tools cover the whole path: workspace provisioning (create_tenant, anonymous, returns the admin key), slideshows including direct .pptx/.pdf upload (upload_pptx), media slides by URL or direct file upload (upload_media), visibility conditions (time of day, weekday, date range, data triggers; show or hide, all or any), edits to what is already playing (update_slide for a slide's duration, hidden flag and live data; update_slideshow for the news ticker, clock, default duration and sharing; delete_slide, delete_slideshow, replace_slideshow_file; list_sources for the ticker's sources, and list_adapters, create_source, update_source_settings, delete_source for fetched feeds; list_sources and get_source_status show each feed's health and last error in plain words, fetch_source_now refreshes one, get_source_items shows what it fetched and test_source_config tries settings before saving; get_brand_guide, update_brand_guide, preview_brand and check_brand read the workspace brand guide, replace its draft, draw sample slides from it and check a slideshow against it, upload_brand_logo and list_brand_previews; a person confirms the guide on the Brand page; get_source_fields for a source's fields, add_weather_alert_timeline, and template upkeep: list_template_categories, get_template, update_template, delete_template, clone_template, get_template_usage, regenerate_template_thumbnail), text slide edits (get_slide_design, update_slide_design, stock photos with search_stock_images), Google Slides import (import_google_slides), copying a page from a shared slideshow (list_shared_slideshows, import_slide), the media library (get_upload_limits, list_media, get_media, update_media, delete_media, list_media_folders, create_media_folder, rename_media_folder, delete_media_folder), removing a screen and broadcast channels (delete_device, create_broadcast_device), editing a schedule window in place (update_schedule_entry), the audit trail, error log and restoring a deleted slideshow (get_audit_trail, get_error_log, restore_slideshow), turning team access off and on (deactivate_member, reactivate_member), platform news (get_platform_version, get_platform_notices) and the help articles, blog and release notes (search_articles, get_article), self-updating template slides driven by live data pushes (update_source, and push sources fed by the user's own system: push_data, get_source_status, create_source_key), devices, schedules with AspectMismatch warnings, playback-mode control (update_slideshow's playbackMode switches a slideshow between the rendered-video stream and a live HTML/CSS loop), playable stream links that work whichever mode a screen is in, pairing the TV in front of the person (pair_device), "play this there" in one call (play_slideshow_find_device), timed schedules (get_schedule, add_schedule_entry, delete_schedule_entry), temporary takeovers (create_takeover, list_takeovers, end_takeover), play-time reports (get_slideshow_plays, get_device_plays), screen locations (update_device, list_devices near a point), the team (list_team, invite_team_member, revoke_team_invitation, remove_team_member), workspace time zone and locale (update_tenant), "which plan are we on and when does it renew?" (get_billing), "which screen is this?" (identify_devices), what is on a screen and why it is black (get_now_slide_png, get_device_diagnosis), a photo or video on a screen in a minute (show_media_on_device, get_show_status), renaming a screen (update_device), one workspace health summary and offline-alert emails (get_workspace_health, get_offline_alerts, set_workspace_offline_alerts, set_device_offline_alerts), AI Studio slides (make_ai_slide, get_ai_slide_job, insert_ai_slides, start_ai_studio_trial), previewing a template before saving it (preview_new_template), undoing a change (undo_change), feedback to the InfoSlides team (report_issue when it gets stuck, leave_testimonial after a job went well; the team may pin a testimonial to the landing page, credited to the agent), PNG slide previews for self-verification, API keys including push-only keys scoped to a single slide, and Paddle checkout links for a chosen plan and billing period. The backend enforces every plan limit, and the tool layer cannot bypass them.

Designing your own live data slide: the agent's guide to templates and pushed data covers how to write a template that reads well on a screen and how to connect a system that pushes data to it.

A [Skill](SKILL.md), which is the judgement the tools do not carry: when a self-updating slide beats a fixed one, how to pick between landscape and portrait, how long a slide should stay up for someone queueing versus someone walking past, how to find a screen by name, edit what is on it and confirm the change reached the wall (renderStatus), and how to talk a person through the TV end of it while they are holding a remote.

The InfoSlides Digital Signage Assistant skill covers the conversation side: it turns what a person says ("turn off the ticker in the lobby", "breakfast menu before 11") into the right tool calls in the right order, says what to tell them back, and includes worked scenarios, designing a slide yourself, and when to report an issue or leave a testimonial. The tool names are the same. Read it at https://infoslides.app/skills/infoslides-assistant/SKILL.md or download infoslides-assistant.zip to install it in Claude or another agent that loads skills.
