MCP tools · 5 exposed · ~877 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. 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 →

Tool Tokens
compare ~264

Deterministically diff an implementation screenshot against a reference screenshot. Returns a pixel-mismatch ratio, width/height deltas, and a ranked list of structural issues (missing/extra elements, position, size, color, shadow, spacing), plus an irreducible-mismatch floor so you know when further pixel-chasing is futile. Inputs are image file paths (PNG/JPG); the same inputs always produce the same numbers.

NameTypeReqDescription
auto_resizeboolean–Resize the implementation to the reference's dimensions before diffing.
disable_ocrboolean–Skip OCR text extraction. OCR runs by default and roughly doubles latency; disable it when you don't need text content or typography (note: extract then returns empty fontSizes).
heatmap_pathstring–If set, write a diff heatmap PNG to this path.
implementation_pathstringyesPath (absolute, or relative to the server's launch directory) to the current build screenshot.
reference_pathstringyesPath (absolute, or relative to the server's launch directory) to the reference (design) screenshot.
regionstring–Limit the diff to a named semantic anchor from the reference.
topinteger–Maximum number of issues to return (default 20).

No output schema declared.

No examples provided.

extract ~168

Analyze a single reference screenshot into structured data an agent can build from: layout regions (position/size), dominant colors, typography, spacing, and a suggested implementation strategy. Returns a compact summary by default; set full=true for the complete report. Input is an image file path.

NameTypeReqDescription
disable_ocrboolean–Skip OCR text extraction. OCR runs by default and roughly doubles latency; disable it when you don't need text content or typography (note: extract then returns empty fontSizes).
fineboolean–Use fine-grained (4px) layout detection for small details.
fullboolean–Return the full detailed report instead of the compact summary.
image_pathstringyesPath (absolute, or relative to the server's launch directory) to the screenshot to analyze.

No output schema declared.

No examples provided.

plan ~105

Generate a suggested implementation plan (layout strategy, CSS primitives, repeated patterns, typography notes) from a reference screenshot. Input is an image file path.

NameTypeReqDescription
disable_ocrboolean–Skip OCR text extraction. OCR runs by default and roughly doubles latency; disable it when you don't need text content or typography (note: extract then returns empty fontSizes).
image_pathstringyesPath (absolute, or relative to the server's launch directory) to the screenshot to analyze.

No output schema declared.

No examples provided.

suggest_fixes ~240

Diff a build against a reference and return concrete, ranked fix observations (size, color, shadow, spacing) with values measured from the reference. Selectors are only emitted when they resolve from real DOM; for screenshot-only input the fixes are region-anchored observations with capped confidence rather than guessed selectors. Inputs are image file paths.

NameTypeReqDescription
disable_ocrboolean–Skip OCR text extraction. OCR runs by default and roughly doubles latency; disable it when you don't need text content or typography (note: extract then returns empty fontSizes).
frameworkstring–Output format: react or vanilla (default react).
implementation_pathstringyesPath (absolute, or relative to the server's launch directory) to the current build screenshot.
reference_pathstringyesPath (absolute, or relative to the server's launch directory) to the reference (design) screenshot.
regionstring–Limit fixes to a named semantic anchor from the reference.
stylingstring–Styling output: tailwind or css (default tailwind).
topinteger–Maximum number of fixes to return (default 20).

No output schema declared.

No examples provided.

tokens ~100

Extract design tokens (color palette, spacing scale, radii) from a reference screenshot. Input is an image file path.
