What

Plugins are add-ons for Claude Code, and some bring MCP servers, outside programs that give Claude extra tools. The settings Claude Code builds for these plugin servers now carry extra markers.

  • pluginOfficialSourceVouched: the step that builds plugin configs takes a new flag. When it is set, each config gets pluginOfficialSourceVouched: true. When it is not, the property is removed.
  • pluginEndpointTemplated: recorded when the server's command, args, env or URL use a variable that gets filled in.
  • Needs user input: a new check treats a config as needing your input if it has user_config or uses the HOME, DESKTOP, DOCUMENTS or DOWNLOADS variables.

Why

The members do not show these markers changing what any plugin server is allowed to do yet. In practice, Claude Code can now tell whether a plugin server came from an official source, whether its endpoint is filled in from variables, and whether it depends on your own settings or folders.
