Gemini CLI + Tintly

Connect Gemini CLI in three steps

Gemini CLI reads MCP servers from settings.json. A streamable HTTP server uses the httpUrl field and can send headers.

1. 1

   Create an API key

   Sign in on the developer page and create a key.

2. 2

   Edit settings.json

   Open ~/.gemini/settings.json (or .gemini/settings.json in a project) and add the block below.

3. 3

   Check it

   Start Gemini CLI and run /mcp to list Tintly and its tools.

{
  "mcpServers": {
    "tintly": {
      "httpUrl": "https://www.trycolorkit.com/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

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 Gemini CLI: if one is rejected, follow its current MCP docs, which only need the address and the Authorization header.

First things to ask Gemini CLI

• Make me a calm, trustworthy palette for a banking app and check the text contrast.
• Which pairs in #0B132B, #1C2541, #5BC0DE, #F4D6B0 and #D97706 are readable as text?
• Explain what the color #2A9D8F says to people, and where it works best.
