Smoother MailerSend MCP experience

Agathe Brusset · 1 min read · September 24th, 2026

The MailerSend MCP is now more reliable and easier for AI assistants to use. We fixed validation errors, improved how it handles activity data, and added a skill that teaches assistants how to use it.

What's more, the MCP can now tell you how far back your activity data goes, so it picks a valid date range the first time. That means fewer failed requests when you ask about past activity.

And finally, you can check your API quota by asking how many API requests you have left and when your quota resets. It's handy before a big send or when you're working out why requests are being limited.
