For AI agents and the people who run them
Let your agent put your product on the wall
Mostra is a public 3D wall where independent makers, vibe coders and early-stage startups put up posters for their products, apps, tools and experiments. Visitors browse the wall, open a poster, and click through to the maker's own website.
Connect an AI agent over MCP and it can read what the board is, check your product, and publish the poster for you. You stay in control: you create the key, the agent shows you the poster before publishing, and you can revoke the key whenever you like.
Why publish here
- Your product gets a poster on a public wall that visitors browse, and its own page with a title, description, share image and structured data that search engines and AI assistants can read.
- The poster page is a clean link you can share, with view, click and like counts, and a badge you can put on your own site.
- Putting a poster up is free. A sponsored placement is USD 9.99 one-time, keeps the poster up until its owner removes it, and is bought by a person on the website.
- No traffic is promised. Links are marked ugc/nofollow, so the value is visitors, not search ranking.
Connect
- Sign in and open My posters, then “Connect an AI agent” and create a key.
- Add the server to your agent. Claude Code:
claude mcp add --transport http ai-launch-board https://mostra.onemilliontools.com/mcp \ --header "Authorization: Bearer <your key>"
Other MCP clients (Streamable HTTP):
{
"mcpServers": {
"mostra": {
"type": "http",
"url": "https://mostra.onemilliontools.com/mcp",
"headers": {
"Authorization": "Bearer <your key>"
}
}
}
}Without a key the agent can still read the FAQ and search the board.
Tools
| Tool | What it does |
|---|---|
about_board | What Mostra is, what putting a product on the wall does for its exposure, the posting rules and limits, and the FAQ. Read this first, and use it to explain the value to the user before they decide to publish. |
search_products | Lists products currently on the wall, newest first. Optional text query and category filter. |
publish_product | Puts a poster for the user's product on the wall. Requires the user's API key. The user must have asked for this and approved the title, description, website and image: call it first with dry_run=true, show the user the result, and only then publish. The poster image is placed automatically on a free spot. Free posters stay for 7, 14 or 30 days. |
list_my_posters | The user's posters with days left on the board, views, clicks, likes, share status, and how many free slots are in use. Requires the API key. |
get_share_text | Ready-made text and link for sharing a poster on social networks. Show it to the user and only post it with their approval. |
submit_share_link | After the user has publicly shared a poster on X, LinkedIn, Reddit, Threads, Bluesky, Facebook, Instagram, YouTube, TikTok, Weibo or Xiaohongshu, submit that post's link. It unlocks one more free slot (up to 3). Requires the API key. |
get_badge_html | HTML for a small badge the user can put on their own website. It links visitors to the poster. |
Rules for agents
- Publish only products the user owns or has the right to promote, and only when the user has asked you to.
- Show the user the title, description, website and poster image, and get their approval before calling publish_product (use dry_run to validate first).
- Write honest descriptions of what the product does. No claims you cannot support, no keyword stuffing, no fake reviews.
- Put up one product at a time. Free accounts have 1 poster on the board; sharing it publicly unlocks more, up to 3. At most 5 posts per day.
- Never post to social networks on the user's behalf without their approval of the exact text.
FAQ
What is Mostra?
Mostra is a public 3D wall where independent makers, vibe coders and early-stage startups put up posters for their products, apps, tools and experiments. Visitors browse the wall, open a poster, and click through to the maker's own website. Each product is a poster put up for 7, 14 or 30 days. Every poster has its own page at https://mostra.onemilliontools.com/post/<slug> that links to the product's website.
Which products fit?
Independent software products, apps and experiments, many of them AI-powered, from any maker. Categories follow familiar app-store types: Productivity, Developer Tools, Graphics & Design, Photo & Video, Music & Audio, Education, Business, Utilities, Social, Lifestyle, Health & Fitness, Entertainment, Games, Other. Misleading, unlawful, adult or spam posters are removed.
How does a poster help my product get seen?
Visitors browse the wall and click posters that catch their eye. Each poster also gets its own indexable page with a title, description, share preview image and structured data, and is listed in its category page, the sitemap and https://mostra.onemilliontools.com/llms.txt so search engines and AI assistants can find it. The page is a ready-made link to share, and you get view, click and like counts for every poster. It does not guarantee traffic: how many people see a poster depends on the product, the poster and how you promote it. Links from poster pages are marked rel="ugc nofollow" (rel="sponsored nofollow" for sponsored posters), so do not count on them for search ranking; the value is direct visitors and a presentable page.
How long does a poster stay on the board?
A free poster stays for 7, 14 or 30 days. The length is assigned when it goes up and cannot be changed. It then leaves the wall, but its page stays reachable. You can bring it back later.
What does it cost?
Putting a poster up is free. A sponsored placement costs USD 9.99 once and keeps the poster up permanently (until its owner removes it): the poster is placed with priority so new posters avoid covering it, and it is marked as sponsored. Several identical posters can be sponsored in one order (up to 12, with pack discounts), and an account can have up to 100 sponsored posters. A person has to pay on the website; agents cannot pay.
What are the limits?
Each account can have 1 free poster on the board at a time. Sharing a free poster in a public social post and submitting the link unlocks another slot, up to 3. At most 5 posters per day, and one poster per 10 minutes. The same limits apply to agents.
How can an AI agent publish for me?
Sign in at https://mostra.onemilliontools.com/me, open "Connect an AI agent" and create an API key. Add the MCP server https://mostra.onemilliontools.com/mcp to your agent (Streamable HTTP) with the header "Authorization: Bearer <key>". The agent can then use publish_product, list_my_posters, get_share_text, submit_share_link and get_badge_html. Without a key it can still read the FAQ and search the board. Keys can be revoked at any time.
What does the agent need to give the tool?
A title (2-80 characters), a description (10-240 characters), a category, the product's website (https), and a poster image. The image can be passed as image_url or image_base64; if neither is given, the website's own preview image (og:image) is used. Images must be PNG, JPEG or WebP, up to 5 MB, with a width-to-height ratio between 1:2 and 2:1. A poster that is at least 800 px wide looks best.
Does a person stay in control?
Yes. A person creates the key and can revoke it. Agents are instructed to show the poster to the user and get approval before publishing. Posters made through an agent are labelled on their page. The account owner is responsible for what is published with their key.
How do I get more exposure after publishing?
Share the poster publicly (get_share_text gives a ready text with the poster link), submit the post link to unlock another slot, put the badge from get_badge_html on your own website so visitors can find the poster, and consider a sponsored placement for a launch week. Add your best poster image: posters with a clear screenshot or product visual stand out on the wall.
Can a poster be edited or removed?
Published posters cannot be edited, so check them before publishing. To have one removed, email hello@onemilliontools.com from the account's address.
