Research: how to publish to Claude Code's official skill/plugin/MCP marketplaces #20
Description
Find out:
- Does Claude Code have an official marketplace for skills, plugins, or MCP servers?
- If so, how do you submit/publish to it? What's the process, requirements, review criteria?
- What's the relationship between the Anthropic connector marketplace (claude.ai connectors) and Claude Code plugins?
- Is there a distinction between the plugin system (installed via
claude plugin install) and the skills system (.claude/skills/)? Do they have separate discovery mechanisms? - What does Anthropic officially endorse vs. what's community-driven?
- How does this compare to what Vercel offers via skills.sh?
This is about understanding all the channels through which echoskill/echomodel content could reach users — not just our own marketplace.
