Connect the Brew MCP server to ChatGPT, Claude, Grok, Cursor, Codex, VS Code, and any major MCP client with OAuth.
Every client connects to the same clean endpoint:
https://brew.new/api/mcp
Brew is its own OAuth 2.1 connector, so the first-party flow needs
no key to copy: add the URL, sign in with Brew, and choose one
brand. Organization admins can instead choose All brands. The
issued connection is revocable anytime in Settings → API.The brew:all OAuth scope grants the selected credential boundary:
full access to one chosen brand, or to the organization when an admin
chooses All brands. Organization connections require brand_id
on brand-scoped tools and expose the brand lifecycle workflow.
Wiring up a headless or CI setup, or a client with no OAuth UI? Send an
API key as Authorization: Bearer brew_… instead. See the API-key
alternative below.

Any client
1
Add a custom connector
Open Settings → Connectors, click Add custom connector, and paste the connection URL:
https://brew.new/api/mcp
2
Connect
Click Connect, sign in with Brew, and pick a brand.
Works with Claude Desktop and claude.ai.
1
Enable Developer mode
Open Settings → Security and login and enable Developer mode.
2
Create the Brew plugin
Open Settings → Plugins, select +, and create a plugin named Brew. Choose Server URL, paste the URL below, and select OAuth authentication:
https://brew.new/api/mcp
3
Approve brand access
Sign in with Brew, pick the brand ChatGPT should use, review the disclosed full-brand access, and approve it.
4
Enable Brew in a new chat
Start a new chat and enable @Brew from the Plugins menu.
5
Verify the catalog
Ask Brew to call get_brew_capabilities. A successful response confirms that ChatGPT loaded the current action catalog.
If an older cached plugin reports an invalid action schema, refresh its actions first. Remove and re-add Brew only after the corrected endpoint is deployed and only if refresh does not work. Your existing OAuth grant remains valid.
1
Create a custom connector
Open grok.com/connectors, select New Connector → Custom, name it Brew, and paste:
https://brew.new/api/mcp
2
Authenticate
Start authentication, sign in with Brew, select a brand, review the full-brand access, and approve it.
3
Verify in a new chat
Start a new Grok chat, enable Brew, and ask it to call get_brew_capabilities.
Grok CLI: run grok mcp add --transport http brew https://brew.new/api/mcp, authenticate from /mcps if needed, then run grok mcp doctor brew.
1
Add the server
Run this in your terminal:
claude mcp add --transport http brew "https://brew.new/api/mcp"
2
Sign in
Claude opens your browser to sign in with Brew and pick a brand.
3
Verify
Start a session and run /mcp to confirm Brew is connected.
1
Open your MCP config
~/.cursor/mcp.json (global) or .cursor/mcp.json (this project).
Reload or restart the client, then sign in with Brew (OAuth) on first connect and pick your brand. If your client can’t do the OAuth handshake, add an Authorization: Bearer <brew key> header instead (see below).
If your client has no OAuth connector UI (or you are wiring up a
headless or CI setup), authenticate with a Brew API key instead.
Create either a brand-scoped key or, as an organization admin, an
organization-scoped key at Settings → API and send it as a bearer
header. The URL stays the same:
Claude Desktop’s connector UI has no header field, so a key uses the mcp-remote bridge: open Settings → Developer → Edit Config, paste this, then fully quit and reopen Claude:
Once connected, ask your agent to call get_brew_capabilities. It returns the tool catalog, credit costs, and the guided workflows. Or smoke-test the endpoint directly with a key:
