## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-03.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 87/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1491 tokens (~114/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 13 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (13)

### `check_launch_readiness` (~127 tokens)

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 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.

Input parameters:

- `url` (string, required): Homepage URL; the https:// prefix is optional

Output parameters:

- `checks` (array)
- `finalUrl` (string): After redirects
- `httpStatus` (integer|null)
- `responseMs` (integer|null): Time to response headers, from SaaSCity servers

- `score` (integer)
- `url` (string)
- `verdict` (string)

### `recommend_launch_directories` (~133 tokens)

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_directories to go wider across all 1,666 sites.

Input parameters:

- `free_only` (boolean): Only picks with a free or freemium route
- `product_type` (string): saas = B2B/B2C software, ai = AI tool or app, devtools = sold to developers, any = general

Output parameters:

- `attribution` (string)
- `dataUpdatedAt` (string): Date link type and price were last swept (YYYY-MM-DD). DR has its own date per row.
- `groups` (array)
- `productType` (string)

### `find_launch_directories` (~213 tokens)

Find launch directories

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.

Input parameters:

- `category` (string): Directory category
- `exclude_badge_exchange` (boolean): Drop directories whose free listing requires their badge on your site
- `limit` (integer): Results per page
- `link_type` (string): dofollow = verified followed link

- `query` (string): Match against directory name or domain, e.g. "hunt" or "betalist"
- `sort` (string): dr = strongest first

Output parameters:

- `attribution` (string)
- `dataUpdatedAt` (string): Date link type and price were last swept (YYYY-MM-DD). DR has its own date per row.
- `directories` (array)
- `offset` (integer)
- `total` (integer): Matches before pagination

### `get_launch_directory` (~94 tokens)

Look up a 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.

Input parameters:

- `domain` (string, required): Directory domain or any URL on it, e.g. "uneed.best" or "https://www.producthunt.com/posts/new"

Output parameters:

### `submit_project` (~207 tokens)

Submit a project to SaaSCity

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.

Input parameters:

- `category` (string, required): Listing category id
- `description` (string, required): Plain text: the problem, who it is for, what makes it different
- `github_url` (string): Public repo URL (optional)

### `check_badge` (~80 tokens)

Check the SaaSCity 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 turns the listing link dofollow.

Input parameters:

- `url` (string, required): Site URL to scan (the listing URL; the homepage is read as well)

Output parameters:

- `badgeSnippet` (string): The HTML to embed when not found
- `code` (string): FOUND, BADGE_NOT_FOUND, UNREACHABLE, TIMEOUT, HTTP_ERROR, ...
- `found` (boolean)
- `message` (string)

### `get_submission_status` (~87 tokens)

Output parameters:

- `offers` (array)

## Common questions

### What is the SaaSCity MCP server?

SaaSCity is an MCP server listed in the public MCP registry as io.saascity/saascity. Audit your site, pick from 1,600+ launch directories by DR and link type, and list on SaaSCity. This page covers its hosted endpoint (https://saascity.io/api/mcp).

### Is the SaaSCity MCP server safe to use?

SaaSCity scores 80 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the SaaSCity MCP server expose?

SaaSCity exposes 13 tools: check_launch_readiness, recommend_launch_directories, find_launch_directories, get_launch_directory, submit_project, and 8 more. Their descriptions and schemas cost roughly 1,366 tokens of context every time the server is loaded.

### Does the SaaSCity MCP server require authentication?

No. We connected to SaaSCity without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the SaaSCity MCP server still maintained?

SaaSCity is still listed as active in the MCP registry. We last reached this channel on 3 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
