15 tools

Deletes or cancels 1Claude Code: deny
  • image_delete_uploadDelete one image stored for your token, uploaded or generated: name is the name it is stored under.No findings

    Why it is in this group

    • The name "image_delete_upload" says "delete": a word for removing or ending something.
    Description, as the server wrote it
    Delete one image stored for your token, uploaded or generated: name is the name it is stored under. image_files lists them. A name nothing is stored under is refused and nothing is deleted.
Can't be undone 1Claude Code: ask
  • image_uploadSend an image to this hosted endpoint.No findings

    Why it is in this group

    • The name "image_upload" says "upload": a word for a change.
    • The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    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.
Changes things 11Claude Code: ask
  • image_batch_resizeCall this tool to resize every image in paths at once, keeping aspect ratio, each named <name>-<W>x<H>.<ext>.No findings

    Why it is in this group

    • The name "image_batch_resize" says "resize": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: false
  • image_compressCall this tool to re-encode an image smaller and report byte counts before/after.No findings

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "image_convert" says "convert": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: false
  • image_cropCall this tool to cut a rectangle out of an image.No findings

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: false
  • image_dominant_colorsCall this tool to read the colours covering most of an image, as hex codes with each one's pixel share.No findings

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: false

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false

    Why it is in this group

    • The name "image_resize" says "resize": a word for a change.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it

    Why it is in this group

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    Call this tool to write one thumbnail per input into out_dir as <name>-thumb.<ext>, fit inside size by size, aspect kept. Paths are reserved before writing, so a collision leaves nothing half-done. Free: 5/call, 4 MP.

  • image_watermarkNot available on this hosted endpoint: the watermark is drawn with bitmap font files loaded from a filesystem, which this endpoint does not have.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
