Windsurf iMessage Integration — Send iMessages from Windsurf IDE

Q: How do I add iMessage to Windsurf IDE?

Add the Sendblue MCP server (sendblue-mcp) to your Windsurf MCP configuration file. Provide your Sendblue API key and secret as environment variables. Once configured, Windsurf's Cascade agent can send and receive iMessages using Sendblue's tools.

Connect Sendblue's MCP server to Windsurf and give Cascade the power to send iMessages. Notify teammates, test messaging features, or build AI-driven text workflows — all from your editor.

How to Connect Windsurf + Sendblue

Create a Sendblue Account

Sign up at dashboard.sendblue.com and copy your API key and secret. The free sandbox lets you test with real iMessage delivery.

Add the MCP Server

Open Windsurf's MCP configuration and add the sendblue-mcp server entry. Point it to the npm package and include your API credentials as environment variables.

Start Using Cascade

Ask Cascade to send an iMessage. The agent uses the MCP tools to call Sendblue's API — send messages, check delivery status, and pull incoming replies.

Key Features

Cascade-Powered Messaging

Windsurf's Cascade agent orchestrates multi-step actions. With Sendblue's MCP tools, those actions now include sending iMessages and reading replies — no context switching.

Flow-Compatible

Incorporate iMessage into Windsurf's Flows for multi-step automations. Generate content, send it via iMessage, process replies, and update your code — all in one Flow.

Real-Time Delivery Status

Check whether messages were delivered, read, or failed. Cascade can poll delivery status and report back without you opening a separate dashboard.

Team Notifications

Wire up iMessage alerts for code reviews, deploy completions, or incident triggers. A quick "text me when the build finishes" instruction to Cascade handles the rest.

Message Attachments

Send images and media URLs along with text messages. Useful for sharing screenshots, design mockups, or generated assets directly to a phone.

Automatic SMS Fallback

Sendblue detects whether a recipient has iMessage. iPhone users get blue bubbles; Android users receive SMS. No manual configuration on your part.

Why Windsurf + iMessage?

Windsurf is built around Cascade — an agentic AI that understands your codebase and can take actions across files, terminals, and now, messaging. By adding Sendblue's MCP server, you unlock a new class of actions: sending real iMessages to real phone numbers.

Practical use cases for developers: You're debugging a messaging feature and need to send test iMessages to verify formatting. Instead of writing a cURL command or opening Postman, you tell Cascade: "Send 'Your appointment is confirmed for 3 PM tomorrow' to +15551234567." Cascade calls the send-message tool through the MCP server and reports the delivery status back in the chat.

For teams building products on Sendblue's REST API, the Windsurf integration cuts feedback loops. You write the code, test it with a real iMessage from within the editor, see the delivery result, and iterate — without switching windows. It pairs well with existing Sendblue CRM integrations for HubSpot, Salesforce, and GoHighLevel where the CRM handles production messaging and Windsurf handles development and testing.

Setup takes about a minute: add the MCP config, provide credentials, and start messaging. No SDK to install, no dependencies to manage, no build steps.

Frequently Asked Questions

How do I add iMessage to Windsurf IDE?

Add the Sendblue MCP server (sendblue-mcp) to your Windsurf MCP configuration file. Provide your Sendblue API key and secret as environment variables. Once configured, Windsurf's Cascade agent can send and receive iMessages using Sendblue's tools.

Is this a native Windsurf plugin?

No. The connection works through Sendblue's MCP server, which implements the Model Context Protocol standard. Windsurf supports MCP servers natively, so no separate plugin is needed — just add the server configuration and your API credentials.

Can I use Windsurf Flows with iMessage?

Yes. Windsurf's multi-step Flows can incorporate iMessage actions through the MCP server. For example, you could build a Flow that generates a message, sends it via iMessage, waits for a reply, and processes the response — all orchestrated by Cascade.

What happens if the recipient doesn't have an iPhone?

Sendblue automatically detects whether a phone number supports iMessage. If the recipient is on Android, the message is delivered as SMS instead. This fallback is automatic — no extra configuration required.
