# Brevo MCP server — security and configuration update

The Brevo MCP server has been updated with improved security, simplified maintenance, and rate limiting.

**What changed:**

* **Authentication method**: MCP tokens are no longer passed in the URL. They are now transmitted securely via the HTTP `Authorization: Bearer <token>` header. All previous URL patterns containing `/{token}` are no longer valid.
* **Auto-generated tools**: The 193 MCP tools are now automatically generated from the Brevo OpenAPI specification, eliminating discrepancies between the API and MCP server.
* **Rate limiting**: Request limits have been added to protect services from abuse.
* **New tool support**: Integration guides now cover [Windsurf](https://windsurf.com), [VS Code (GitHub Copilot)](https://code.visualstudio.com/), and [Claude Code CLI](https://code.claude.com) in addition to Claude Desktop, Cursor, and Cline.

**Action required**: Update your MCP configuration to use the new header-based authentication. See the [integration guide](/docs/integration-guide) for updated configuration examples for all supported tools.
