Mailjet API client
Most team communication work still happens through a UI a human drives. Node MCP server moves it into the conversation instead. Mailjet API client.
Welcome to the [Mailjet][mailjet] official JavaScript SDK built with webpack, babel & es5. \ This can be used in node or in the browser.
The server publishes 4 tools. What each one is for:
v3.1 — The Email Send API v3.1, which is the latest version of our Send APIAuthentication — The Mailjet Email API uses your public and secret keys for authenticationOptions — options have this structure: - headers - associative array describing additional header fields which you can pass to the request - timeout -Config — config have this structure: - host - sets custom host URL - version - sets required version of API for determinate endpoint (set of v3, v3.1, v4) -Installation goes through your MCP client rather than a global install: point it at node-mailjet on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: MJ_APIKEY_PUBLIC, MJ_APIKEY_PRIVATE, MJ_API_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Node's toolset — v3.1, Authentication, Options and 1 more — is a fair guide to whether it matches your workflow. It is maintained by oleksandr-mazepa; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Node's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
