Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security70
  • No malware found by supply-chain analysis.Pass
  • CVE check failed: a known high-severity CVE affects sharp 0.33.5, a direct dependency. A fixed version is available. View diagnostics → Fail
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (126 of 130), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability64
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 564 tokens (~564/item across 1 items; 1 tools + 0 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 Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 1 exposed · ~564 tokens

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.

Tool Tokens
get_diff_of_images ~564

Compare two images pixel-by-pixel and identify visual differences. Returns structured diff data including: - Overall diff percentage and pixel counts - Clusters of different regions with bounding box coordinates (x, y, width, height) - Severity rating per cluster (trivial/minor/moderate/major) - Clustering metadata with the gap used and suggestions for tuning - File paths to generated heatmap images showing diff intensity **Clustering**: By default, nearby diff regions are automatically grouped using a natural-breaks algorithm that finds the optimal merge distance. This produces a manageable number of clusters where each represents a distinct problem area. To override, set cluster_gap explicitly (0 = no merging, or a specific pixel distance). **Heatmap output**: A PNG image where diff regions are colored from yellow (subtle difference) to red (major difference). A composite version overlays this on the source image for easy comparison. **Use cases:** - Compare a design mock screenshot against actual UI implementation - Compare a Figma mock of a single component against a full-page screenshot (auto-aligned) - Detect visual regressions between two versions of a page - Verify CSS/layout changes only affect intended areas **Requirements:** - Images must be accessible as local file paths - Images can have different dimensions — the smaller image is automatically aligned within the larger one using template matching **Note:** Anti-aliased pixels (font smoothing, rounded corners) are excluded by default to reduce false positives. Set include_aa=true to include them.

NameTypeReqDescription
cluster_gapinteger—Maximum pixel distance between cluster bounding boxes to merge them into a single cluster. When omitted, an optimal gap is auto-computed using natural breaks in cluster distances. Set to 0 to disable…
include_aaboolean—Whether to count anti-aliased pixels (font smoothing, rounded corners) as differences. Default false excludes them to reduce noise.
min_cluster_sizeinteger—Minimum number of connected diff pixels to report as a cluster. Filters out isolated pixel noise. Default 4.
source_imagestringyesAbsolute file path to the source/reference image (e.g. the design mock). Supports PNG, JPEG, WebP, TIFF.
target_imagestringyesAbsolute file path to the target/comparison image (e.g. the actual UI screenshot). Supports PNG, JPEG, WebP, TIFF.
thresholdnumber—Color matching sensitivity from 0 to 1. Lower values detect subtler differences. 0.1 is a good default for UI comparison. Use 0.05 for strict comparison or 0.2 for lenient.
