What MCP.so does for a launch

Developer directories list libraries, open-source projects, APIs, self-hosted apps and MCP servers. Developers search them with a job in mind, and many are built from GitHub repos or pull requests rather than a submit form, so a clear README matters as much as the listing.

How to get listed on MCP.so

  1. Check how MCP.so adds projects: a submit form, a pull request to a list, or automatic indexing from GitHub or a package registry.
  2. Make your README do the selling: what it does in one line, a screenshot or GIF, install steps and a license.
  3. Pick the most specific category or tag; developers browse narrowly.
  4. If MCP.so works from pull requests, follow its contribution guide exactly: format, alphabetical order and description length.
  5. Keep the project active. Many developer directories rank or hide projects by recent commits and releases.

Tips for MCP.so

  • Include clear setup instructions for the popular clients; that's what visitors come for.

What to prepare before you submit

You'll paste the same things into every launch platform and directory, so write them once:

  • A tagline under 60 characters that says what it does (see how to write a product tagline).
  • A description under 160 characters, plus a longer one of two or three short paragraphs.
  • A square logo (at least 256×256) and three or four screenshots at the same size.
  • Your pricing in one line, including whether there's a free plan.
  • A spreadsheet of where you submitted, the listing URL and whether the link is followed.

Frequently asked questions

Is listing on MCP.so free?
Most developer and open-source directories are free, and some are community-maintained lists you add to by pull request. Check MCP.so's submit or contributing page for its current rules.
Does my project need to be open source for MCP.so?
It depends on the directory. Open-source lists require an open-source license, while API, MCP and tool directories often accept closed-source and paid products too. MCP.so's submission rules say which.
Does a MCP.so listing help SEO?
It helps developers discover the project and gives search engines another page about it. Links from lists on GitHub and many directories are nofollow, so the value is mostly in being found.

IndieLaunch isn't affiliated with MCP.so. What's here comes from its own site, checked October 18, 2026; prices and policies change, so check before you submit. Our full list is in the startup directories guide.
