Anthropic opens Claude plugin submissions

Anthropic opened a plugin submission portal for Claude developers, with MCP 2.0 and two supported extensions now available to paid-plan builders. The new Claude plugin portal accepts a remote MCP connector or a bundle of MCP servers and skills, auto-validates submissions, and publishes usage analytics after approval. For teams extending agents, this shifts discovery from bespoke install instructions toward a reviewed catalog; keep plugin auth and version telemetry in your release plan, especially as agent skill libraries already lose retrieval precision at scale.
