Claude Desktop + Tintly

Connect Claude Desktop in three steps

Claude Desktop starts local MCP servers from a config file. Tintly is a remote server, so the config uses the small mcp-remote bridge, which sends your key in the Authorization header.

1. 1

   Create an API key

   Sign in on the developer page and create a key.

2. 2

   Open the config file

   In Claude Desktop open Settings, then Developer, then Edit Config. This opens claude_desktop_config.json.

3. 3

   Add Tintly and restart

   Paste the block below into the file (merge it into mcpServers if you already have servers), save, and restart Claude Desktop.

{
  "mcpServers": {
    "tintly": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://www.trycolorkit.com/api/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer YOUR_API_KEY"
      }
    }
  }
}

The key sits in env, with no space in the header argument: this is the usual workaround for spaces in arguments on Windows.

Server address: https://www.trycolorkit.com/api/mcp. Replace YOUR_API_KEY with a key from the developer page. Field names can change between releases of Claude Desktop: if one is rejected, follow its current MCP docs, which only need the address and the Authorization header.
