Summary
On August 6, 2026, GitHub released Agent Plugins 1.0, an open standard that bundles agent skills and Model Context Protocol servers into a single installable plugin that works across compatible agent clients. Initial publishers include AWS, Anysphere, Microsoft, OpenAI, and Vercel, with Google joining as a core maintainer, and the spec is governed independently of any single vendor.
What changed
GitHub published Agent Plugins 1.0, a vendor-neutral open standard that packages agent skills plus MCP servers into one installable plugin usable across agent clients, launching in VS Code, Copilot CLI, and the Copilot app.
Why it matters
A shared plugin format lets developers build agent capabilities once and run them across many clients, removing the per-platform packaging burden and reducing lock-in. Independent governance with AWS, Microsoft, OpenAI, Google, and Vercel signals an industry attempt to standardize the agent extension layer on top of MCP.
Evidence excerpt
You can now build a plugin once and use it across all compatible agent clients. Agent Plugins 1.0 was published with AWS, Anysphere, Microsoft, OpenAI, and Vercel, and Google joined as a core maintainer.
