1414This page is for developers deciding which of those pieces their plugin needs. Once you've decided, [Plugin structure and testing](/docs/plugins/build), [Build an MCP server for Claude](/docs/connectors/building/index), and [Publish to the directory](/docs/directory/publish) cover the work.

17 * If you're choosing what to add to your own Claude rather than what to build, see [Connectors, skills, and plugins](/docs/extend/overview), which compares the three from the user's side
18 * If you're building for your own organization and not listing publicly, the same decisions apply, and you distribute the result as a [custom connector](/docs/connectors/custom/add-unlisted#add-a-connector-by-url) and an [organization plugin](/docs/plugins/admin) instead of through the directory

5755In a plugin, you reference a remote MCP server by URL. If a user has both your directory connector and your plugin installed, Claude sees one set of tools, because the plugin and the connector point at the same server.
