Note

If you don't see the Personal tab in Browse plugins:

• If no plugins are installed yet, first install any Anthropic plugin to activate the Personal section: go to Browse plugins, filter by Anthropic, and install any plugin (for example, Marketing). The Personal → + option will appear.
• If your organization restricts personal plugin installations, ask your admin to install the plugin through Organization settings → Plugins.

Find the Reteno plugin in the list and click Install.

You can update the plugin manually from the same menu.

Step 5. Connect your Reteno account

Go to Customize → Reteno → Connectors, enter https://mcp.reteno.com, and click Connect. Sign in to Reteno in the browser window that opens and confirm access.

Tool Permissions

After connecting, you'll see a list of Reteno API tools. By default, the agent asks for confirmation before using each tool. If you prefer to skip these prompts, set individual tools to Always allow.
