Connect Brand Kit OS directly to AI tools via the Model Context Protocol
Last updated: March 3, 2026
Connect Your AI Tools to Brand Kit OS
Brand Kit OS offers three ways to connect your AI tools for live access to your brand context. Choose the method that fits your workflow.
🔌 Method 1: Remote Connector (Recommended)
Best for: Claude.ai, Claude Desktop, Claude Mobile
The Remote Connector uses OAuth 2.0 with PKCE — no API key needed. Claude authenticates directly with your Brand Kit OS account.
Setup Steps
- Open Claude (web, desktop, or mobile)
- Go to Settings → Connectors → Add Custom Connector
- Enter the following details:
- Connector Name: Brand Kit OS (or any name you prefer)
- Connector URL:
https://fupwpcqmyykfiuakjxxc.supabase.co/functions/v1/mcp-server
- Click Connect — you'll be redirected to Brand Kit OS to log in and authorize
- A popup will ask if you want to open in Claude — click Yes
- Claude will refresh and the connector will appear as active
Important Notes
- Authentication required: If you're not logged in to Brand Kit OS, you'll be redirected to the login page first
- No Client Secret needed: The connector uses PKCE (Proof Key for Code Exchange), so no secret is required
- Mobile access: Once connected on desktop, the connector is also available on Claude Mobile automatically
- OAuth Client ID:
bk_claude_connector_v1(auto-configured — you don't need to enter this)
What You Get
- All 12 MCP tools available directly in Claude
- Live access to your brand kits — always up to date
- No API key to manage or rotate
- Works across Claude web, desktop, and mobile
🧩 Method 2: Cowork Plugin (Claude Desktop)
Best for: Claude Desktop users who want skills + auto-load
The Cowork Plugin bundles MCP tools with pre-built skills and a hook that loads your brand context automatically at the start of every conversation.
Setup Steps
- In Brand Kit OS, go to Settings → Integrations
- Click Download Cowork Plugin (generates a
.zipwith your API key baked in) - Unzip into your Claude Desktop plugins folder:
- macOS:
~/Library/Application Support/Claude/plugins/ - Windows:
%APPDATA%\Claude\plugins\
- macOS:
- Restart Claude Desktop
- Verify: type "What brand kits do I have?" — Claude should respond with your data
What's Included
plugin.json— Plugin manifesthooks.json— Auto-loads brand context on conversation startskills/voice-enforcement.md— Enforces your brand voice in all outputsskills/brand-context-loader.md— Pulls full brand context into conversations
🛠️ Method 3: Other AI Tools (API Key)
Best for: Cursor, Claude Code, or any MCP-compatible client
These tools connect via API key authentication using the MCP remote transport.
Generate an API Key
- Go to Settings → Integrations in Brand Kit OS
- Click Create API Key
- Copy and store the key securely (it won't be shown again)
Cursor Configuration
Add to your Cursor MCP settings (.cursor/mcp.json):
{
"mcpServers": {
"brandkit-os": {
"command": "npx",
"args": [
"-y", "@anthropic-ai/mcp-remote",
"https://fupwpcqmyykfiuakjxxc.supabase.co/functions/v1/mcp-server",
"--header", "Authorization:Bearer YOUR_API_KEY"
]
}
}
}
Claude Code Configuration
claude mcp add brandkit-os \
-- npx -y @anthropic-ai/mcp-remote \
https://fupwpcqmyykfiuakjxxc.supabase.co/functions/v1/mcp-server \
--header "Authorization:Bearer YOUR_API_KEY"
Replace YOUR_API_KEY with the key you generated.
Troubleshooting
| Issue | Solution |
|---|---|
| "Authentication error" | Ensure your API key is active in Settings → Integrations |
| Remote Connector won't connect | Check that you're using the correct Server URL. Make sure you're logged in to Brand Kit OS |
| Authorize page shows login instead of consent | Log in to Brand Kit OS in your browser first, then retry the connector setup |
| "Request path invalid" error | Ensure the URL ends with /mcp-server — do not add trailing slashes or extra paths |
| Tools not appearing | Restart your AI tool after connecting |
| "No brand kits found" | Make sure you have at least one brand kit created |
| Plugin not loading | Verify the plugin folder path and restart Claude Desktop |
| OAuth redirect loop | Clear your browser cookies for brandkitos.com and try again |
