Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2514 tokens (~147/item across 17 items; 15 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage99
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 98% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 17 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
image_batch_resize Resize several images at once ~166
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.
| Name | Type | Req | Description |
|---|---|---|---|
| height | integer | – | Target height in pixels |
| out_dir | string | yes | Not a directory here: every output comes back as its own download link valid for one hour. Any value is accepted and ignored |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| paths | array | yes | Names of images uploaded with image_upload |
| width | integer | – | Target width in pixels |
No output schema declared.
No examples provided.
image_compress Compress an image ~240
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.
| Name | Type | Req | Description |
|---|---|---|---|
| max_bytes | integer | – | Largest the output may be, in bytes. The server searches JPEG quality down from `quality` until it fits and reports the quality it used. JPEG output only |
| max_width | integer | – | Scale down so the width is at most this, keeping the aspect ratio. Never scales up |
| out_path | string | yes | Name for the file to write; it comes back as a download link valid for one hour. The extension decides the output format; without a known one the input's format is kept |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
| quality | integer | – | JPEG quality 1-100, default 80 |
No output schema declared.
No examples provided.
image_convert Convert an image to another format ~186
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.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | yes | The output format |
| out_path | string | yes | Name for the file to write; it comes back as a download link valid for one hour. The extension decides the output format; without a known one the input's format is kept |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
| quality | integer | – | JPEG quality 1-100, default 80. Ignored for the other formats |
No output schema declared.
No examples provided.
image_crop Crop an image ~226
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.
| Name | Type | Req | Description |
|---|---|---|---|
| height | integer | yes | Height of the crop in pixels |
| out_path | string | yes | Name for the file to write; it comes back as a download link valid for one hour. The extension decides the output format; without a known one the input's format is kept |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
| width | integer | yes | Width of the crop in pixels |
| x | integer | yes | Left edge of the crop, in pixels from the left of the image |
| y | integer | yes | Top edge of the crop, in pixels from the top of the image |
No output schema declared.
No examples provided.
image_delete_upload Delete a stored image ~55
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.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
No output schema declared.
No examples provided.
image_dominant_colors Read the dominant colours of an image ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| count | integer | – | How many colours to report, default 5 |
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
No output schema declared.
No examples provided.
image_files List uploaded and generated images ~31

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
image_info Inspect an image ~75
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.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
No output schema declared.
No examples provided.
image_resize Resize an image ~190
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.
| Name | Type | Req | Description |
|---|---|---|---|
| fit | string | – | inside = fit within the box, cover = fill and crop, exact = stretch |

| width | integer | – | Target width in pixels |
No output schema declared.
No examples provided.
image_strip_metadata Strip metadata from an image ~158
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.
| Name | Type | Req | Description |
|---|---|---|---|
| out_path | string | yes | Name for the file to write; it comes back as a download link valid for one hour. The extension decides the output format; without a known one the input's format is kept |

No output schema declared.
No examples provided.
image_thumbnails Make thumbnails ~158
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.
| Name | Type | Req | Description |
|---|---|---|---|
| out_dir | string | yes | Not a directory here: every output comes back as its own download link valid for one hour. Any value is accepted and ignored |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| paths | array | yes | Names of images uploaded with image_upload |
| size | integer | – | Longest side of the thumbnail in pixels, default 256 |
No output schema declared.
No examples provided.
image_upload Upload an image to work on ~372
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.
| Name | Type | Req | Description |
|---|---|---|---|
| image_base64 | string | – | The image file, base64-encoded |
| name | string | yes | Name to refer to this image by: 1-64 characters of letters, digits, underscore or dash, e.g. "shot" |
| url | string | – | url: fetch a public file instead of pasting base64 (recommended above about 10 KB). Public http(s) only; private, link-local and this endpoint's own zone are refused |
No output schema declared.
No examples provided.
image_watermark Watermark an image with text ~231
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.
| Name | Type | Req | Description |
|---|---|---|---|
| opacity | number | – | 0.05 to 1, default 0.5 |
| out_path | string | yes | Name for the file to write; it comes back as a download link valid for one hour. The extension decides the output format; without a known one the input's format is kept |
| overwrite | boolean | – | Replace out_path if it already exists. Default false. Never allows an output to be one of the inputs |
| path | string | yes | Name of an image uploaded with image_upload, or one this server wrote earlier |
| position | string | – | Where to draw it |
| text | string | – | The watermark text. Default: the business name from the shared profile. Custom text is Pro |
No output schema declared.
No examples provided.
license_activate Activate license ~76
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.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | License key from checkout, MCPL1.<payload>.<signature> |
No output schema declared.
No examples provided.
license_status License status ~55
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.
Input schema present but exposes no named parameters.
No output schema declared.
