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

Tools

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.
