Discover plugins in Xcode
Xcode 27 adds an open plugin format bundling skills, MCP tools, and bring-your-own agents.
“With the agent client protocol, a plugin can bring an agent of your choice.”
Apple's Xcode 27 introduces a community-adopted plugin format that packages skills (markdown task instructions), MCP tools, and—via the agent client protocol—custom agents, installable by CLI, Git URL, or one-click from partners like Figma and GitHub. It signals Apple aligning its IDE with the emerging open agent-tooling stack (MCP and ACP), but it's incremental dev-tooling news rather than a major industry shift.
