Anthropic opens a submission portal for Claude plugins with an automated safety scan on every upload

Sources: primary, discussion
Summary: The 2026-09-25 announcement opens a directory submission portal to developers on paid plans, where a submission is either a single remote MCP server or a bundle of MCP servers and Agent Skills hosted in a GitHub repository, and in Claude Code a bundle can also carry LSPs, commands, hooks and agents. Each submission is validated and safety-scanned on upload, with the scan results and recommended changes shown in the review status, and the developer controls when an approved plugin publishes. The post states Claude supports the MCP 2.0 spec with a stateless core and names two extensions, MCP Apps for interactive UI inside chat and Enterprise Managed Auth for OAuth.
Why it matters: The post publishes no pricing, no review time, and no description of what the safety scan checks, so a developer cannot estimate either the cost of listing or the strength of the gate.
Follow-up: Track publication of the safety scan criteria and the review turnaround, and the rollout of the single discovery experience across Claude and Claude Code.
