Agent Plugins 1.0.0 ships as a vendor-neutral package format, ending per-client repackaging of Skills and MCP servers
Vercel published Agent Plugins 1.0.0 on August 6, 2026 — an openly licensed spec that packages Agent Skills and MCP servers behind one portable manifest: a plugin.json needing only schemaVersion and name, a skills/ directory, an mcp.json, and reverse-DNS subdirectories (com.example.client/) for client-specific extensions. Vercel initiated the proposal and AWS, Anysphere, GitHub, Microsoft and OpenAI refined it; the Technical Steering Committee draws Core Maintainers from Amazon, Cursor, Microsoft, OpenAI and Vercel. ChatGPT, Codex, Cursor, GitHub Copilot, Kiro and VS Code support it at launch, and the spec repo (agentplugins/agent-plugins-spec) carries a conformance checklist defining the minimum a client must implement to discover and load a plugin.
