theluckystrike McpStamp Image Tools MCP

An MCP server providing image manipulation capabilities including resizing, converting formats, compressing, cropping, generating thumbnails, stripping EXIF/GPS metadata, and adding watermarks. It supports both local installation via npm and hosted access via a token-based URL, operating without requiring account creation or email for the free tier.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Image editing for PNG, JPEG, BMP, GIF and TIFF files. It covers size and format details, resizing single images or batches, format conversion, compression, cropping, thumbnails, stripping EXIF, GPS and other metadata, and dominant colours. McpStamp's hosted service has no file system, so images arrive as base64 uploads or public URLs, are kept per user account, and results come back as one-hour download links; text watermarks are not available here. The free tier handles sources up to 4 megapixels and 5 files per batch. One lifetime key unlocks this server and all 58 others: https://mcp.zovo.one/buy/bundle?src=instr.image

image_info — Inspect an image
Advertised by the server during the last successful anonymous check.

Call this tool to inspect an image: format, pixel dimensions, megapixels, file size in bytes, and whether it carries an alpha channel. Read-only, never modifies the file. Free tier: unlimited, any size.

image_resize — Resize an image
Advertised by the server during the last successful anonymous check.

Call this tool to write a resized copy. fit inside keeps aspect; cover fills and crops; exact stretches. One of width/height alone keeps aspect. Input untouched. Free: sources up to 4 MP.

image_convert — Convert an image to another format
Advertised by the server during the last successful anonymous check.

Call this tool to re-encode an image as PNG, JPEG, BMP, GIF or TIFF. quality is JPEG-only. Transparency converted to JPEG flattens onto white; the answer says so. Free tier: sources up to 4 MP.

image_compress — Compress an image
Advertised by the server during the last successful anonymous check.

Call this tool to re-encode an image smaller and report byte counts before/after. quality (default 80) applies to JPEG; for PNG only max_width shrinks it, and the answer names which one worked. Free: sources up to 4 MP.

image_crop — Crop an image
Advertised by the server during the last successful anonymous check.

Call this tool to cut a rectangle out of an image. x, y are the top-left corner in pixels from the image's top-left. A rectangle past an edge is refused with the image's real size, not clamped. Free: sources up to 4 MP.

Advertised by the server during the last successful anonymous check.

image_watermark — Watermark an image with text
Advertised by the server during the last successful anonymous check.

Not available on this hosted endpoint: the watermark is drawn with bitmap font files loaded from a filesystem, which this endpoint does not have. Watermark on a local install instead - download image.mcpb from https://github.com/theluckystrike/mcp-servers/releases/latest and open it in Claude Desktop - or upload an image you have already watermarked.

image_strip_metadata — Strip metadata from an image
Advertised by the server during the last successful anonymous check.

Call this tool to write a copy carrying pixels and nothing else: it decodes and re-encodes from raw pixels, so EXIF, GPS, camera, capture time, XMP and colour-profile data are dropped. Free tier: sources up to 4 MP.

image_batch_resize — Resize several images at once
Advertised by the server during the last successful anonymous check.

Call this tool to resize every image in paths at once, keeping aspect ratio, each named <name>-<W>x<H>.<ext>. One of width/height lets the other follow; with both, each fits inside the box. Free: 5 files a call, 4 MP.

image_dominant_colors — Read the dominant colours of an image
Advertised by the server during the last successful anonymous check.

Call this tool to read the colours covering most of an image, as hex codes with each one's pixel share. Sampled from a 200 px copy, so cost is fixed. Read-only. Free gives the top 3; Pro up to 16.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

image_upload — Upload an image to work on
Advertised by the server during the last successful anonymous check.
Advertised destructive

Send an image to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with image_upload and then pass its name as `path` (or inside `paths`) to image_info, image_resize, image_convert, image_compress, image_crop, image_thumbnails, image_batch_resize and image_dominant_colors. PNG, JPEG, BMP, GIF and TIFF are accepted and the format is read from the file's magic bytes, not from the name. Give exactly one of image_base64 or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): writing out a real photo as base64 is a long tool call and 50 KB or more can stall the turn before the upload is sent, while a url costs one line and the fetch happens here (10 second timeout, at most 3 redirects, public http(s) hosts only, 2 MB cap). Uploads are kept for your token between calls; image_files lists them and image_delete_upload removes one. A file this server writes is named the same way and comes back as a download link valid for one hour, served with the real image content type. The request body cap is 256 KB, which is about 190 KB of image once base64-encoded.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http mcpstamp-image-tools-mcp https://mcp.zovo.one/mcp/image

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add mcpstamp-image-tools-mcp --url https://mcp.zovo.one/mcp/image

Cursor

Merge this server into .cursor/mcp.json in your project, then enable mcpstamp-image-tools-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "mcpstamp-image-tools-mcp": {
      "url": "https://mcp.zovo.one/mcp/image"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "mcpstamp-image-tools-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.zovo.one/mcp/image",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start mcpstamp-image-tools-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "mcpstamp-image-tools-mcp": {
      "type": "http",
      "url": "https://mcp.zovo.one/mcp/image"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http mcpstamp-image-tools-mcp https://mcp.zovo.one/mcp/image

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://mcp.zovo.one/mcp/image

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "mcpstamp-image-tools-mcp": {
      "serverUrl": "https://mcp.zovo.one/mcp/image"
    }
  }
