What you actually get
A listing on a marketplace that publishes its own numbers on the submit page: DR 72, 2.2 million unique visitors and 6 million pageviews over twelve months, 266,000 monthly active users, and 57,000 backlinks from 2,580 referring domains. It indexes servers, remote servers, clients, CLI tools, loops, skills and agents separately, so an MCP project lands in the right shelf rather than in a general pile.
How to submit to MCP.so
1
Pick a project type
/submit opens with four tabs: MCP Server, Remote Server, MCP Client and AI Agent. The type decides which shelf the listing lands on.
2
Give the repository URL
Repository URL is the only required field; Name is optional and presumably read from the repo.
3
Sign in
The Sign In control sits in the header and the submission attaches to an account.
4
Choose free or $39
The paid card is on the same page: $39 one-time for immediate publication, a verified badge, featured placement and a followed link. The free lane goes into review.

Gotchas
The followed link is one of the four things the $39 fee buys, alongside instant publication, the verified badge and featured placement. A free listing gets a page and a nofollow.
The free lane's turnaround is not stated anywhere: the paid card's selling point is publishing without review, which is the only clue that the free one waits.
The listing is built from a repository URL, so a closed-source hosted server needs a public repo describing itself before it can be submitted at all.
Let your agent submit to MCP.so
Connect SubmitMap to your AI over MCP and this page stops being something you read and copy. Your agent asks for the MCP.so playbook and gets the brief for this exact form, with the values already taken from your submission pack instead of placeholders you fill in by hand.
