Install Lightsage MCP in Claude Code

Connect Claude Code to Lightsage MCP with a remote HTTP server and the X-Lightsage-Api-Key header.

Claude Code supports remote HTTP MCP servers and custom authentication headers. Use this guide to connect Claude Code to the hosted Lightsage MCP endpoint.

1. Get your Lightsage API key

Open the Lightsage dashboard, copy your API key, and store it as LIGHTSAGE_API_KEY:

export LIGHTSAGE_API_KEY="ls_cli_your_api_key"

Do not put your API key in shared project config, screenshots, issue reports, or public repositories.

2. Add the Lightsage MCP server

Add Lightsage as a remote HTTP MCP server:

claude mcp add --transport http lightsage https://mcp.lightsage.com/mcp \
  --header "X-Lightsage-Api-Key: ${LIGHTSAGE_API_KEY}"

You can also use a shared .mcp.json with environment variable expansion:

{
  "mcpServers": {
    "lightsage": {
      "type": "http",
      "url": "https://mcp.lightsage.com/mcp",
      "headers": {
        "X-Lightsage-Api-Key": "${LIGHTSAGE_API_KEY}"
      }
    }
  }
}

3. Verify Claude Code sees Lightsage

Check that Claude Code can load the server:

claude mcp list

Then run a read-only prompt:

Use the Lightsage MCP server to check my Lightsage auth status.

See the Claude Code MCP docs for scopes, approval, and OAuth behavior.
