How to Use the MailerSend MCP in Windsurf

Q: How do I set up the MailerSend MCP Server inside Windsurf?

Open your local config file at /.codeium/windsurf/mcpconfig.json and add the server configuration under the mcpServers key. Cascade automatically reads the schema and registers the 12 tools.

Q: Can Windsurf update my MailerSend templates without manual exports?

Yes, Cascade chains the listemailtemplates and gettemplatedetails tools to compare local files with remote layouts. It writes changes directly to your files or warns you about missing variables.

Q: How does Windsurf track failed transactional emails using MailerSend?

Cascade executes listemailactivities to pull recent logs directly into your terminal pane. It analyzes the error codes and points to the exact line in your code causing the failure.

Q: Can I view active webhooks from my workspace?

Use the listdomainwebhooks tool to inspect active endpoints through this MCP integration. Your agent displays active configurations directly in your sidebar so you don't have to check the external dashboard.

Let the MailerSend MCP Server trigger transactional emails and check delivery logs directly from Cascade without leaving your workspace.

Perplexity

Automate template audits directly inside Windsurf

The `list_email_templates` tool lets your agent pull your active layouts right into the Windsurf editor. Cascade reads your local layout files, compares them with your remote MailerSend templates, and updates mismatched variables instantly. You do not need to copy and paste code back and forth between a browser and your IDE. When a marketing change breaks a variable, Cascade uses `get_template_details` to isolate the missing keys and patch your local configuration file.

Chain transactional testing with Cascade

The `send_transactional_email` tool acts as the core engine when Cascade runs live integration tests. Your agent writes a test payload, triggers the email, and monitors the response block inside your workspace. Instead of manual verification, Cascade links this operation with `get_message_info` to verify delivery in real time. If the test bounce rate spikes, the agent flags your local DNS settings before you commit your code.

Monitor MailerSend MCP Server quotas dynamically

The `get_account_limits` tool exposes your current monthly sending thresholds to your IDE environment. Windsurf reads these limits before initiating high-volume batch tests, preventing API lockout during development. When your local test scripts trigger rate limits, Cascade reads the headers and schedules the next test batch automatically. This integration keeps your local sandbox running without manual intervention.
