Extension Registry

Browse, search, install, and manage extensions from the AgentOne extension registry.

The extension registry is a curated catalogue of MCP servers that AgentOne knows how to install and configure. You access it from Settings -> Extensions.

Browsing the Registry

The registry page lists available extensions with the following information for each:

  • Name and description - what the extension does.
  • Version - the version AgentOne will install.
  • Icon and category badges - a quick visual indicator of the extension's purpose.
  • Connection type - whether the server runs on your device (STDIO) or connects to a remote service (HTTP).
  • Website link - a link to the extension's own documentation or homepage.

Without any filters applied, the list is sorted to show built-in extensions first, then installed extensions, then everything else.

Search and Filters

Use the search field to filter by name or keywords. The filter menu adds:

  • Show only installed - narrows the list to extensions you have already installed.
  • Connection type filter - Runs on this device (STDIO) or Connects online (HTTP).

These filters can be combined with a search query.

Install Status

Each extension row shows its current status:

  • No badge - not installed.
  • Installed and showing a status indicator - enabled, loading, disabled, or error.

If an extension shows Unsupported, AgentOne cannot install it from the available registry data. This typically means the server requires a transport type or configuration format that AgentOne does not yet support.

Advanced View

Installed extensions gain an Advanced button. The advanced panel exposes:

  • Current load status and any error messages.
  • Per-tool approval overrides.
  • Auth connection controls for HTTP extensions that require sign-in.
  • A Restart action for an enabled extension that is no longer responding.
  • Debug information for some registry extensions, useful when troubleshooting.

Edits in this view are drafts until you click Save in the footer. Click Cancel to leave the installed configuration unchanged.
