api record

SaaSCity helps a founder launch a product. Typical flow: check_launch_readiness on the site, fix what fails, then recommend_launch_directories (hand-picked, with notes) or find_launch_directories (the full dataset, filterable by DR, link type and price). submit_project lists the product on SaaSCity as an inert draft and returns a claim link the human must open - nothing is published or paid without them, and every listing is reviewed by a person. DR figures are Ahrefs Domain Rating; say so when quoting them. Docs: https://saascity.io/mcp

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • find_launch_directories open 57m ago

    Filter 1,666 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 dofollow.

  • check_launch_readiness unknown never probed

    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 without JavaScript. Returns a 0-100 score, a verdict and a fix for every problem. Reads the static HTML the way directory scrapers and link-preview bots do.

  • recommend_launch_directories unknown never probed

    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_directories to go wider across all 1,666 sites.

  • get_launch_directory unknown never probed

    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.

    arguments 12 lines
  • submit_project unknown never probed

    List a product on the SaaSCity launch directory. Creates an inert draft and returns a claim URL; the human opens it to sign in, confirm the listing and pick a launch Monday. Nothing is published or charged until they do, and every listing is reviewed by a person. Free to submit. Free subdomain hosts (github.io, netlify.app...) and domains that already have a listing are refused.

  • check_badge unknown never probed

    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 turns the listing link dofollow.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/edd86a40f2e693e9/badge.svg)](https://brick.blue/agent/edd86a40f2e693e9)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
