• contrast_check

  rnv-color-mcp

  WCAG contrast ratio between a foreground and background color, for accessibility. Both accept a hex, CSS name, RNV brand name, or saved-palette reference. Returns the ratio (1.0-21.0) plus pass/fail for AA and AAA at normal and large text sizes and for UI components. Read-only and deterministic, with no side effects. Use this for legibility and accessibility checks; to measure raw perceptual difference between two colors rather than readability use color_difference instead.

• get_audio_features

  FreqBlog Music Metadata

  Get audio features for ONE track — BPM, musical key (name + Camelot + Open Key), energy, danceability, valence, acousticness, instrumentalness, liveness, speechiness, loudness, mood, mood_vector, genre, time signature, duration and more. This is the drop-in replacement for Spotify's deprecated /audio-features endpoint. Provide EXACTLY ONE identifier: - `track` (optionally with `artist`) — e.g. track="Blinding Lights", artist="The Weeknd". - `isrc` — e.g. "USUM71900001". - `mbid` — a MusicBrainz recording UUID. - `spotify_id` — a Spotify track ID, URI, or URL (resolves only the ~2.4% of the catalog already mapped to a Spotify ID; prefer `track`/`isrc` for full coverage). Returns a JSON object of features. Some feature fields may be null for tracks resolved via the fallback catalogs (only audio-derived values are present for fully analysed tracks). If a track name is not yet in the catalog, the API queues an on-demand analysis and this tool reports that it is queued — retry in ~30s-2min. If you only have a fuzzy or partial name, call search_catalog first to find the exact track.

Uses K-means++ extraction plus Bradford chromatic adaptation for accuracy. Returns up to 5 dominant colours, each with archive name, cultural story, nearest RAL standard, and WCAG accessibility data. Works for product photography, interior photos, artwork, brand assets, and mood boards. The image is never stored — processed in memory only.

• shippingrates_total_cost

  freightgate-mcp-server

  Calculate the full landed cost of shipping a container — combines freight rates, surcharges, local charges (origin + destination), demurrage/detention estimates, and transit time into one comprehensive estimate. This is the most comprehensive tool — a single call replaces 5-6 individual queries. Use this when the user needs an all-in cost estimate for a specific shipment. For individual cost components, use the dedicated tools: shippingrates_rates (freight), shippingrates_surcharges, shippingrates_local_charges, shippingrates_dd_calculate (detention). PAID: $0.15/call via x402 (USDC on Base or Solana). Without payment, returns 402 with payment instructions. Returns: { freight: { rate, currency }, surcharges: { total, items[] }, local_charges: { origin: { total, items[] }, destination: { total, items[] } }, detention: { days, cost, currency }, transit: { days, service }, total_landed_cost, currency }

• evaluate_typography

  Axcess — Design Accessibility Evaluation

  Evaluates typography elements against a principled accessibility rubric. COST: $0.05 USDC via x402 on Base-compatible EVM network per call. Goes beyond what axe/Lighthouse/WAVE can check — evaluates design judgment, not just numeric compliance. Catches issues like: - Contrast that passes WCAG 4.5:1 but fails visually due to thin font weight - Body text that meets minimum size requirements but is still too small for comfortable reading - Line heights that technically comply but impede readability for dyslexic users - Extended all-caps or italic text that passes all AA criteria but impairs reading - Text on gradient/image backgrounds where scanner sampling is unreliable - Heading sizes that are technically correct but visually indistinct from body Args: - elements: Array of 1–50 typography element objects with font/color properties - screen_name: Optional label for the evaluation report Each element requires: element_type, font_size, font_weight, line_height, color_hex, background_color_hex. Returns: Structured report with: - Per-element scores (0–100) - Specific issues with severity (critical/major/minor) - WCAG references and what automated tools miss - Concrete fix recommendations - Overall score and verdict (pass/needs_work/fail) - Top issues sorted by severity Example use: Extract text layer properties from Figma using get_design_context, pass the typography properties to this tool for evaluation before shipping.
