How to Use the Courier MCP in Windsurf

Q: Will this work with my custom templates in Courier?

Of course. The listtemplates tool exposes all your notification templates to your agent. Windsurf can see them and use the right one when you ask it to send a notification.

Give Windsurf's Cascade agent the keys to Courier. It'll send notifications, check delivery status, and manage users for you. All from your IDE.

Automate Notification Workflows

Tell Cascade to notify a user about a new deployment. It'll grab the right template, fire off the message with `send_notification`, and report back. No more context switching to a dashboard. Then, you can ask it to confirm delivery. Cascade can use `get_message_details` and `get_message_history` to pull the full event log, including provider responses, right into your editor. You get the full picture without clicking around.

Manage Audiences and Users with this MCP Server

Need to check a user's notification settings before sending? Just ask. Cascade will use `get_user_profile` to pull their contact info and channel preferences. It can also run `list_users` to give you a quick dump of everyone in the workspace. Your agent can even manage audiences. Set a goal like "show me our most active subscriber lists" and Cascade will chain `list_subscription_lists` with other tools to get you an answer. It's about giving your agent the context it needs to perform real tasks.

Keep Notifications On-Brand

Your agent needs to know which notification to send. With this connection, Cascade can run `list_templates` to see all available templates and their supported channels. This helps it make smarter decisions about what to send and where. This also works for branding. A quick call to `list_brands` gives your agent the info it needs to apply the right logos and colors. This ensures every automated notification that goes out from Windsurf looks exactly right.
