Using another client? Here is how to connect Brein

If your tool accepts remote MCP servers, it can use Brein. You don’t need a guide for each app: they all ask for the same thing.

What you need

Brein’s address:
https://api.trybrein.com/mcp
Pick sign-in (OAuth) when the app asks how to authenticate. You don’t need a client ID, a secret or a key: the app registers itself with Brein.
Sign in to Brein and approve. Your browser opens, you sign in with your account, pick your workspace and approve. Done.

Then ask it this to test:

Show me the Brein workspaces I can use and how many credits I have left.

Menu names change often. If you can’t find one, search for «MCP» or «Connectors» in your app’s settings.

App	Where
ChatGPT, Claude, Codex and Cursor, OpenClaw	They have their own guide.
VS Code with Copilot	In the `mcp.json` file, under `"servers"`, add `"brein": { "type": "http", "url": "https://api.trybrein.com/mcp" }`. Careful: VS Code uses `servers`, not `mcpServers`; that’s the most common mistake when copying from another guide.
Mistral Le Chat	Intelligence → Connectors, custom connector, OAuth authentication.
Windsurf, Goose, Gemini CLI and others	In their MCP settings, add a remote server (Streamable HTTP) with Brein’s address and sign in when asked.

It asks for	What it means
A required client ID or secret	That app can’t register itself. Write to us and we’ll work it out with you.
A key or a token	That app can’t sign in with OAuth. With OAuth, every action is in a person’s name; that’s why it’s the path we recommend. See permissions and access.
A command to start a local server	That option is for servers that run on your machine. Brein is remote: look for the remote or by-URL server option.

Your yes stays in Brein. Anything that spends credits or sends email asks you to confirm, no matter which app you ask from. More in what needs your yes.
You see the same as in the dashboard: your workspaces, your Cerebro, your Lists, your pipeline and your Sequences.
You can remove access whenever you want in Brein, under Settings → Security & Data. The app can no longer get in.
