Luminary Lane — Claude Cowork Plugin

Brand intelligence for Claude. Draft on-brand content, check voice alignment, and generate campaign briefs — all powered by your real brand data from Luminary Lane.

Prerequisites

Before installing this plugin, you need:

1. A Luminary Lane account — Sign up at luminarylane.app
2. At least one brand set up with voice and tone guidelines
3. Claude Desktop (with Cowork access)

Setup

Step 1: Generate an API Key

1. Go to app.luminarylane.app/profile/api-keys and sign in
2. Click Generate New Key
3. Copy the key (starts with ll_mcp_) — you won't be able to see it again

Step 2: Install the Plugin

In Claude Desktop, install the plugin from GitHub:

https://github.com/raveenb/lane-plugin

Step 3: Configure the MCP Connection

Since this plugin uses API key authentication (not OAuth), you need to add the MCP server config to your Claude Desktop settings.

On macOS, edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "lane": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.luminarylane.app/mcp",
        "--header",
        "X-API-Key:${LANE_API_KEY}"
      ],
      "env": {
        "LANE_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Replace YOUR_API_KEY_HERE with the key you generated in Step 1.

On Windows, the config file is at %APPDATA%\Claude\claude_desktop_config.json.

Step 4: Restart Claude Desktop

Quit and reopen Claude Desktop for the MCP connection to take effect.

Step 5: Verify

Open a new Cowork conversation and try:

/draft-post brand=YourBrandName topic=product launch

If you see Claude loading your brand's voice and tone data, you're all set.

Commands

/draft-post — Draft a LinkedIn Post

Creates a post using your brand's voice, tone, and active campaign context.

/draft-post brand=Acme topic=product launch
/draft-post brand=Acme campaign=Q1Launch
/draft-post                              # interactive — asks which brand

/check-voice — Brand Voice Check

Evaluates whether a piece of text matches your brand voice and provides a revised version.

/check-voice brand=Acme text="Your draft copy here..."
/check-voice brand=Acme                  # then paste your text

Returns:

• Alignment score (Strong / Good / Needs Work)
• What matches well
• What could be improved
• A revised on-brand version

/campaign-brief — Campaign Context Brief

Generates a structured brief combining brand foundation, campaign strategy, and content recommendations.

/campaign-brief brand=Acme
/campaign-brief brand=Acme campaign=Q1Launch

Auto-Activation

When you discuss marketing or content creation topics in a Cowork conversation, the plugin automatically activates and offers to load your brand data. You don't need to use a slash command — just describe what you need.

"I need to write a social media post for our product launch next week"

Claude will recognize this as a marketing task, list your brands, and load the relevant context.

Troubleshooting

"Brand not found"

The brand name must match exactly as it appears in your Lane dashboard. Run /draft-post without arguments to see your available brands.

MCP tools not appearing

• Make sure claude_desktop_config.json is saved and Claude Desktop has been restarted
• Check that your API key starts with ll_mcp_ and was copied correctly
• Verify the MCP server is reachable: curl https://mcp.luminarylane.app/health

"Too many concurrent sessions"

This can happen if you have multiple Claude Desktop windows open. Close unused windows or wait a few minutes for stale sessions to expire.

"Authentication failed"

Your API key may be invalid or revoked. Generate a new one at app.luminarylane.app/profile/api-keys.
