| Tool | What it does |
|---|---|
check_launch_readiness | Audits a homepage the way directory scrapers and link-preview bots see it: HTTPS, noindex, title, meta description, og:image (fetched to confirm it loads), X card, favicon, canonical, viewport, h1, JSON-LD, robots.txt, sitemap, parked or 404 pages, response time, and pages that are empty without JavaScript. Returns a 0-100 score, a verdict and a fix for each problem. |
recommend_launch_directories | Hand-picked directories for SaaS, AI or developer tools, grouped by when to submit. Each pick has a human-written verdict, including the ones not worth paying for. |
find_launch_directories | Filters the full dataset (1,600+ startup, SaaS and AI directories) by category, minimum DR, dofollow/nofollow, price and badge-swap requirement. Unverified fields come back as unknown instead of a guess. |
get_launch_directory | Looks up one directory by domain or URL before you pay for a listing. |
submit_project | Lists a product on SaaSCity as an inert draft and returns a claim link. Nothing is published or charged until a human opens it, and every listing is reviewed by a person. |
check_badge | Checks whether the SaaSCity badge is live on a site (a verified badge makes the listing link dofollow). |
get_submission_status | Where a submission stands, by claim token or listing slug. |
get_launch_weeks | Free slots left in the next 12 weekly launches. |
get_offers | Listing tiers and prices. |
search_listings | Searches products listed on SaaSCity by keyword and category. |
get_listing | One listing in full. |
get_leaderboard | Most upvoted launches this week, in the last 30 days, or all time. |
find_alternatives | Other listings in the same category as a given one. |
Every tool declares an outputSchema and returns structuredContent next to its text, plus readOnlyHint and the other behavior hints. Only submit_project writes anything, and it writes only a draft.
plan_launch (website_url, product_type): audit, fix the blockers, pick directories, produce a dated launch checklist.submit_to_saascity (website_url): draft a listing from the site, confirm it with you, then submit it.Check if https://example.com is ready to launch, then give me a two-week launch plan for an AI tool using free dofollow directories.
Is uneed.best worth it? What's its DR and is the link dofollow?
List my product on SaaSCity. The site is https://example.com.
drCheckedAt is the date of its last recheck, or null when the value comes from the last sweep of the list. Link type and price come from checks against the live sites, dated by dataUpdatedAt. Rows nobody has verified say unknown.submit_project 5 per day, check_launch_readiness 20 per hour, check_badge 30 per hour, everything else 30-60 per minute.submit_project is the only way a draft becomes a listing.MIT for this bridge.
