Qué puede hacer

Nombres y descripciones de las herramientas tal como los informó el servidor el 7 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.

  • check_launch_readiness

    Audit a product homepage before launching it: HTTPS, noindex, title and meta description, og:image (fetched to confirm it loads), X card, favicon, canonical, mobile viewport, h1, JSON-LD, robots.txt, sitemap, parked or 404 pages, response time, and whether the page is empty witho

  • recommend_launch_directories

    Hand-picked launch directories for a product type, grouped by when to submit (launch day first, evergreen after). Every pick carries a human-written verdict, including the ones that are not worth paying for, plus Ahrefs DR, link type and price. Start here; use find_launch_directo

  • find_launch_directories

    Filter 1,667 startup, SaaS and AI directories by category, minimum Ahrefs DR, link type (dofollow/nofollow), price and badge-swap requirement. Returns submit URLs. Link type and price are "unknown" where nobody has verified them yet - treat those as unverified, not as free or dof

  • get_launch_directory

    Look up one directory by domain or URL: Ahrefs DR, dofollow or nofollow, price, whether it wants a badge swap, the submit URL, and a human verdict where one exists. Use it to vet a directory before paying for a listing.

  • submit_project

    List a product on the SaaSCity launch directory. Creates an inert draft and returns a claim URL; the human opens it to sign in, gets the submit form prefilled with the draft, picks a plan and a launch Monday and submits the form. Nothing is submitted, published or charged until t

  • check_badge

    Check whether the SaaSCity badge is live on a site. Reads the given URL and, for a deep page, the site homepage too, rendering JavaScript if the static HTML misses it. A verified badge keeps a free listing booked before November 6, 2026 on a dofollow link. A paid listing needs no

  • get_submission_status

    Where a SaaSCity submission stands. By claim token: unclaimed, expired, claimed but the form not submitted yet, submitted and waiting for payment, submitted and in review, rejected, archived, or live. By slug: a live listing (launch week, badge, link type, points).

  • get_launch_weeks

    SaaSCity launch weeks: the next 12 Mondays. A round opens each Monday at 00:00 UTC, and a paid listing can take any of them.

  • get_offers

    SaaSCity listing offers with real prices - Basic listing and Premium listing - and exactly what each buys (dofollow link, city-map building, launch review). Every new listing is paid. Only a human can pay, on the claim page.

  • search_listings

    Search products listed on SaaSCity by keyword and/or category. Returns title, tagline, category, upvote points, the listing page and the product site. Useful for market research ("what else exists in this space?") before a launch.

  • get_listing

    One live SaaSCity listing by slug: title, tagline, full description, category, upvote points, link type (dofollow/nofollow), listing page and product site.

  • get_leaderboard

    SaaSCity's most upvoted launches for this week's launch, the last 30 days, or all time, optionally within one category.

  • find_alternatives

    Other SaaSCity listings in the same category as a given listing, most upvoted first. Useful for competitor research and positioning.

  • calculate_arr

    Turn monthly recurring revenue into annual recurring revenue (ARR = MRR x 12), with ARPU when the customer count is given and the months to $100k, $1M and $10M ARR at a monthly growth rate. Count annual plans at their yearly price divided by 12 and leave one-time fees out of MRR.

  • calculate_arr_bridge

    Explain how ARR moved over a period: ending ARR = starting ARR + new + expansion - contraction - churned. Returns net new ARR, growth, the SaaS quick ratio ((new + expansion) / (contraction + churned)), and net and gross revenue retention of the starting base. Full calculator: ht

  • calculate_churn

    Customer churn and retention for a period, its monthly and annual equivalents (compounded, so 5% a month is about 46% a year, not 60%), and the average customer lifetime. Full calculator: https://saascity.io/free-tools/churn-rate-calculator

  • calculate_nrr

    Net revenue retention (NRR) and gross revenue retention (GRR) of a group of customers from their starting MRR, expansion, contraction and churned MRR, with annualised figures. Full calculator: https://saascity.io/free-tools/net-revenue-retention-calculator

  • rule_of_40

    Rule of 40 score (revenue growth % + profit margin %), plus the magic number, burn multiple and SaaS quick ratio when their inputs are given. Full calculator: https://saascity.io/free-tools/rule-of-40-calculator

  • calculate_nps

    Net Promoter Score from the counts of promoters (9-10), passives (7-8) and detractors (0-6), with the margin of error at 95% confidence. Full calculator: https://saascity.io/free-tools/nps-calculator

  • ab_test_significance

    Two-proportion test of an A/B result: conversion rates, relative uplift, p-value, confidence interval, the chance that B beats A, and a sample ratio mismatch check. Full calculator: https://saascity.io/free-tools/ab-test-calculator

  • markup_margin

    Selling price, profit and margin from a cost and a markup percent, or markup and margin from a cost and a selling price. Full calculator: https://saascity.io/free-tools/markup-calculator

  • uptime_downtime

    Allowed downtime per day, week, month, quarter and year, in seconds, for an availability target such as 99.9%. Full calculator: https://saascity.io/free-tools/uptime-calculator

  • check_backlink

    Check whether a directory listing page links to your site and whether that link is followed. Reads the page's static HTML and reports every anchor pointing at your domain with its rel (nofollow, ugc, sponsored), hidden links, links that only go through the directory's own redirec

Preguntas frecuentes

¿Es seguro SaaSCity?

Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.

¿Qué claves o códigos necesita?

El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

¿Se ejecuta en mi computadora o en la nube?

Funciona de las dos formas: instálalo en tu computadora o conéctate a la versión en la nube.

¿Sigue en mantenimiento?

El repo de GitHub cambió por última vez –, y la última versión (2.1.0) llegó al registro hoy.

¿Qué apps pueden usarlo?

Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

¿Qué puedo usar en su lugar?

SaaSCity MCP server

An MCP server for launching a product. Your AI agent can audit your homepage before launch, pick launch directories out of 1,600+ with Ahrefs DR, link type and price, and list the product on SaaSCity.

  • Remote, keyless: https://saascity.io/api/mcp (Streamable HTTP). No account, no API key.
  • Stdio: npx -y saascity-mcp for clients that only run local servers. It forwards to the hosted server.
  • Protocol: MCP 2026-07-28 (stateless) and the initialize-based versions 2025-11-25, 2025-06-18, 2025-03-26 and 2024-11-05, all on one endpoint.

Built by SaaSCity, the launch directory for SaaS and AI tools. Full docs: saascity.io/mcp

Install

Claude Code

claude mcp add --transport http saascity https://saascity.io/api/mcp

Claude Desktop, Cursor, Windsurf, VS Code and other clients with `mcpServers` JSON

{

"mcpServers": { "saascity": { "type": "http", "url": "https://saascity.io/api/mcp" } } }

Stdio-only clients

{

"mcpServers": { "saascity": { "command": "npx", "args": ["-y", "saascity-mcp"] } } }

It also runs straight from GitHub: npx -y github:nyyhao/saascity-mcp.

Tools

ToolWhat it does
check_launch_readinessAudits 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_directoriesHand-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_directoriesFilters 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_directoryLooks up one directory by domain or URL before you pay for a listing.
submit_projectLists 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_badgeChecks whether the SaaSCity badge is live on a site (a verified badge makes the listing link dofollow).
get_submission_statusWhere a submission stands, by claim token or listing slug.
get_launch_weeksFree slots left in the next 12 weekly launches.
get_offersListing tiers and prices.
search_listingsSearches products listed on SaaSCity by keyword and category.
get_listingOne listing in full.
get_leaderboardMost upvoted launches this week, in the last 30 days, or all time.
find_alternativesOther 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.

Prompts

  • 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.

Try 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.

Data and limits

  • DR is Ahrefs Domain Rating. 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.
  • The data is the same as on Best SaaS Directories and Best AI Directories.
  • Rate limits are per IP: submit_project 5 per day, check_launch_readiness 20 per hour, check_badge 30 per hour, everything else 30-60 per minute.
  • The server keeps no session and needs no cookies. The claim link from submit_project is the only way a draft becomes a listing.
