In depth
MCP server
Brevo's MCP server works with Claude Desktop and other MCP clients and is set up with an API key. It offers one main server and individual servers by area. source ↗
Plans
The free plan lets you upload contacts and, after approval, send up to 300 emails a day. Starter begins at 5,000 emails a month and lists MCP for ChatGPT and Claude among its features. Checked 2026-10-18. source ↗
How to use it with AI
How Brevo connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Not documented MCP client named in Brevo's docs. A named plugin, skill or CLI does not by itself establish an MCP/native connector pairing. Verify the route and client setup. Brevo named integration docs ↗Claude (incl. Claude Code) MCP docs ↗ | Not documented Claude (incl. Claude Code): Claude Code edits files and runs commands Brevo publishes an API, but this pairing still needs network, authentication and execution-scope checks. Brevo API ↗Claude (incl. Claude Code) docs ↗ | Inferred Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers). Brevo is a web app; the pairing itself is not documented. Claude (incl. Claude Code) browser docs ↗ | Not documented Verify which side exports and which imports, supported formats and permissions. Brevo's recorded upload/import status is to-verify; Claude (incl. Claude Code)'s file status is yes. These flags do not establish a file-transfer route. Claude (incl. Claude Code) file docs ↗ |
| OpenAI Codex | Not documented Brevo has an official MCP server and OpenAI Codex supports MCP, but Brevo's docs don't name this pairing. Auth setup may differ.

Confirmed is reserved for evidence of the specific connection route. The current named integrations include plugins, skills and CLIs, so a named platform alone does not confirm MCP or a native connector. Inferred means each side documents a relevant capability, but no document describes the pairing. Code execution still needs network and credential access; file handling still needs a compatible format and transfer direction. Not documented means the records do not establish the route. IonBin has not tested these pairings. Recorded Oct 18, 2026.

Connection capabilities to compare
An official MCP server is documented for this tool. These platforms separately document MCP client support: ChatGPT, Claude, Cursor, Gemini (Google), Google Antigravity, Grok, Grok Bot, Lindy, LM Studio, Mistral Vibe, OpenAI Codex. This inventory does not establish compatible transport, authentication or actions for a pairing. Check the connection matrix and linked sources.
Automation hubs to assess for a custom API connection: Gumloop, Make, n8n, Zapier. Verify credentials, supported requests, limits and error handling; no configured integration is implied.
