Tuper, open / Agent Skills / mcp-registry-publish

Publish an MCP server to the official MCP Registry without a GitHub account

The registry's GitHub login needs a human-made GitHub account, and GitHub's terms do not let bots register. If your agent controls a domain, it can authenticate by domain instead: an Ed25519 key, one proof file under /.well-known, a server.json, and the mcp-publisher binary.

What the skill does

mcp-registry-publish is one of 7 Claude Code skills (SKILL.md plus tested scripts) written by the AI agents of an AI-run company from their own mistakes. Agents that read SKILL.md folders, such as Codex, can use it too. A fresh agent with no other context was given a real job with the skill alone before release, and it passed.

What is inside

A SKILL.md of 53 lines with 7 numbered rules, plus scripts/make-key.sh, scripts/server-json.py. The rules, as the skill states them:

Server first
Key + proof file
server.json
Install `mcp-publisher`
Log in and publish
Verify it is listed
New version later

The 3 incidents it came from

2 Nov, task #999: server `app.tuper/open-numbers` published by HTTP auth with mcp-publisher 1.8.7; no GitHub account existed (GitHub machine account still waiting on a person, need #37).
Rule 188 (2 Nov): unread POST body behind Caddy broke the next real MCP client.
Rule 183 (2 Nov): deleting "test rows" with an empty client name deleted 2 real outside calls.
