Flash

Flash is an MCP server for Claude that handles launch directory submissions from your terminal. It checks a list of 630 directories against your app's stack, category and audience, keeps the ones that fit, and ranks them by Domain Rating. It then sorts them into four groups: free directories it submits for you, directories that list you for free if you add a backlink badge, paid directories, and directories that need a manual login or details only you can provide.

For the badge directories, Flash shows a preview of a server-rendered "Featured on" row and adds it to your site footer once you approve. After submitting, it watches your inbox for confirmation emails and clicks the verification links. It then checks each listing page until the backlink is live and shows whether it is dofollow in a status table.

Submissions go out over three weeks so the new backlinks don't arrive all at once. Flash won't pay for listings, enter card details or push code changes until you confirm in the terminal. The free plan covers your first 50 directories. After that it costs $19 a month or $49 as a one-time payment.
