imagcon-mcp

# imagcon-mcp

Local MCP server that wraps the Imagcon API so assistants can generate PWA icon sets (all sizes, maskable assets, manifest.json) and iOS splash screens without opening the site. Runs as a stdio process via uvx — no hosted service dependency, no persistent connections.

Requirements

• Python 3.11–3.12

• uv (provides uvx)

• An Imagcon API key starting with ic_live_ from imagcon.app/api-keys

Related MCP server: Nano Banana

Install

The package is self-hosted (not on PyPI). Install directly from the wheel:

claude mcp add imagcon -- uvx --from https://imagcon.app/downloads/imagcon_mcp-0.2.5-py3-none-any.whl imagcon-mcp --api-key ic_live_...

Or with the key in the environment instead of on the command line:

claude mcp add imagcon -- uvx --from https://imagcon.app/downloads/imagcon_mcp-0.2.5-py3-none-any.whl imagcon-mcp

export IMAGCON_API_KEY=ic_live_...

For other MCP clients (Cursor, Windsurf, VS Code, Cline, Zed, Warp, Continue.dev), use the equivalent stdio config:

{
  "mcpServers": {
    "imagcon": {
      "command": "uvx",
      "args": ["--from", "https://imagcon.app/downloads/imagcon_mcp-0.2.5-py3-none-any.whl", "imagcon-mcp", "--api-key", "ic_live_..."]
    }
  }
}

Tools

Images

• generate_image — AI-generate a source image from a text description. Returns image_key and a preview URL. Show the preview to the user and confirm before generating icons.

• save_image — Save a generated image to your gallery by image_key and name.

• list_saved_images — List all saved source images with keys and preview URLs.

• create_icons_from_key — Generate a full PWA icon set from an already-saved image_key — no re-generation, no upload. Same output as generate_pwa_icons.

Icon sets

• generate_pwa_icons — AI-generate a source image, then resize to all PWA sizes, save the set, download the ZIP, extract to output_dir (default ./public/icons).

• create_pwa_icons_from_image — Same PWA pipeline from an existing local PNG/JPEG/WebP at image_path (no AI generation).

• list_saved_icon_sets — List saved icon sets with IDs.

• download_icon_set — Download a saved icon set ZIP by set_id, extract to output_dir.

• get_icon_set_download_url — Get an authenticated download URL for a saved icon set ZIP by set_id.

Splash screens

• generate_splash_screens — AI-generate a source image and produce 16 iOS splash screens, extract to output_dir (default ./public/splash).

• create_splash_screens_from_image — Same splash pipeline from an existing local PNG/JPEG/WebP at image_path (no AI generation).

• create_splash_screens_from_key — Same splash pipeline from an existing image_key (e.g. from generate_image or list_saved_images) — composites the icon on each canvas size without re-generating.

• download_splash_screens — Download a saved splash screen set ZIP by set_id, extract to output_dir.

• get_splash_screen_download_url — Get an authenticated download URL for a saved splash screen set ZIP by set_id.

Account

• get_credit_balance — Returns remaining Imagcon credits.

• setup_wallet_profile — Activate a permanent Imagcon account after a pay-per-call x402 payment. Pass wallet address, profile token from X-Imagcon-Token, name, terms_confirmed (after reading https://imagcon.app/terms-of-service), and a wallet signature over imagcon.app/profile/activate:{profile_token}:{unix_timestamp}.

AI image generation (generate_image, generate_pwa_icons, generate_splash_screens) and icon/splash set exports use credits. create_pwa_icons_from_image, create_splash_screens_from_image, create_splash_screens_from_key, and create_icons_from_key skip AI generation credits but still charge for export.

Configuration

If the key is missing, the process exits with an error pointing to imagcon.app/api-keys.

API base URL

All requests go to https://imagcon.app (no other base URL is supported).
