33> Extend Claude Desktop on 3P with connectors, plugin marketplaces, organization plugins, skills, and hooks for administrators and end users

5Claude Desktop on third-party (3P) supports the same extensibility model as standard Claude Desktop ([MCP connectors](/docs/connectors/overview), [skills](/docs/skills/overview), and [plugins](/docs/plugins/overview)), with the key difference that administrators provision them through managed configuration and the filesystem rather than the claude.ai admin console.

4848See the [`managedMcpServers` schema](/docs/third-party/claude-desktop/configuration#managedmcpservers) in the configuration reference for every field, including static headers, OAuth, and the headers-helper executable for short-lived tokens.

5050In the in-app configuration window, each server you add under **Connectors** has a **Test this connection** button that runs a live MCP `initialize` and `tools/list` against the server using the headers or OAuth settings you've entered, then shows the round-trip latency, the discovered tool list, or the error returned. Use it to validate reachability and credentials before exporting the configuration.

52Give each remote server's final address in `url`. Claude Desktop doesn't follow HTTP redirects from a managed MCP server, or from its OAuth authorization server when it fetches that server's metadata or requests and refreshes tokens. If one of these requests is answered with a redirect, for example to the same address with a trailing slash, the server doesn't connect, and **Test this connection** reports that redirects are not followed. Remote servers that [organization plugins](#organization-plugins-admin) declare in `.mcp.json` follow the same redirect rule.
