Markitup MCP server

markitup-mcp-server

MCP (Model Context Protocol) server for MarkItUp — AI-powered image annotation and marketing-visual generation. Lets Claude Code, Claude Desktop, Cursor, ChatGPT-with-MCP, and other MCP-compatible clients call MarkItUp directly.

Five tools available: markitupcreditbalance, markitupgenerate, markitupregen, markitupextend, markitupremove_background.

Prerequisites

1. A MarkItUp account — sign up at https://markitup.app.
2. A MarkItUp API key — generate one at https://markitup.app/dashboard.
3. Node.js 18 or newer (only if installing locally; npx doesn't require a local Node.js if your MCP client bundles one).

Configure in Claude Code

Add to your MCP config (~/.claude/mcp.json or project-scoped .mcp.json):

{
  "mcpServers": {
    "markitup": {
      "command": "npx",
      "args": ["-y", "markitup-mcp-server"],
      "env": {
        "MARKITUP_API_KEY": "mk_live_..."
      }
    }
  }
}

Configure in Claude Desktop

Edit ~/Library/Application Support/Claude/claudedesktopconfig.json (macOS) or %APPDATA%\Claude\claudedesktopconfig.json (Windows):

{
  "mcpServers": {
    "markitup": {
      "command": "npx",
      "args": ["-y", "markitup-mcp-server"],
      "env": {
        "MARKITUP_API_KEY": "mk_live_..."
      }
    }
  }
}

Configure in Cursor

Cursor uses the same JSON shape. Settings → MCP → Add Server:

{
  "mcpServers": {
    "markitup": {
      "command": "npx",
      "args": ["-y", "markitup-mcp-server"],
      "env": { "MARKITUP_API_KEY": "mk_live_..." }
    }
  }
}

Tools

markitupcreditbalance

Returns the current credit balance and subscription status.

No arguments. Use it to verify your API key works and to check credits before calling generation tools.

markitup_generate

Generates 3 polished marketing-visual variations from a screenshot. Costs 1 credit.

Returns: the marketing copy (headline, sub-headline) plus 3 generated image variations as base64 image content blocks. The full structured response is also available under structuredContent.

Example prompt (in Claude Code):

Use markitupgenerate with the screenshot at https://example.com/dashboard.png — highlight the export button and pitch it for a marketing landing page using the boldmarketing template.

markitup_regen

Regenerate one variation from a previous markitupgenerate call. Costs 1 credit by default (chargecredit: false to skip).

Shortened. The full README is on GitHub.
