Rive MCP tools 32

• riv_listRecursively find .riv files under a directory and report size and format version for each.
• riv_inspectExtract full metadata from a .riv file: artboards, animations (duration/fps/loop), state machines and their inputs (name/type/initial value). Uses the official Rive runtime. Also decodes Data Binding (ViewModel) structure when present — ViewModel definitions and their properties, ViewModelInstances with resolved property values (including enum/nested-viewmodel/list references), enums, converters, and DataBind wiring (which target object/property each bind writes to) — via direct binary parsing (returned as `dataBinding`, omitted when the file has none).
• riv_render_frameRender one frame of a .riv animation or state machine to PNG. Returns the image inline and saves it to disk.
• riv_render_gifRender a .riv animation (or state machine idle playback) to an animated GIF file for preview.
• riv_render_apngRender a .riv animation (or state machine playback) to an animated PNG (APNG). Unlike GIF this supports 24-bit color plus full alpha transparency, and GitHub READMEs animate it like a regular image. Frames are rendered with a transparent background by default.
• riv_play_state_machineRun a .riv state machine step by step: set/fire inputs, advance time, observe state transitions, and optionally capture frames. Returns a transition report.
• riv_generate_codeGenerate ready-to-use integration code (React/Vue/Svelte/plain JS/Flutter) for a .riv file, using its real artboard, state machine and input names.
• riv_dumpLow-level dump of a .riv file's object stream (typeKeys, property values, hierarchy). Useful for debugging and format research. Large files return a summary unless full=true.
• riv_lintStatic diagnostic pass over a .riv file: broken/out-of-range references, oversized embedded assets, state-machine states unreachable by any transition, unconditional self-transitions (infinite-loop risk), unused state-machine inputs, keyframe easing silently discarded on a track's last keyframe, plus motion-quality rules (all-linear robotic movement, teleporting objects, missing stagger on simultaneous fade-ins, one-sided scale animation). Complements riv_dump (which shows raw structure but doesn't judge it).
• riv_design_tokensDeterministically generate professional design tokens for a scene BEFORE calling riv_create: an OKLCH-harmonized palette (with WCAG contrast ratios), gradient pairs, Material-Motion-derived durations & easing roles, spacing/radius/stroke scales and a type scale. Call this first, then use ONLY the returned values in the scene spec — never invent raw hex colors or ad-hoc durations. Inputs: optional seed color, mood (calm|playful|elegant|tech|warm|natural), scheme (dark|light).
• riv_critiqueOne-call review bundle for the render→critique→revise loop. Returns (1) a FILMSTRIP image — N frames left→right across the duration, so motion is readable as a sequence, (2) an ONION-SKIN image — all frames ghost-overlaid so every mover leaves a visible trail (use it to check trajectories and travel direction vs the artwork's facing), (3) a MOTION REPORT — net displacement/rotation vector per animated object computed from the file data, (4) objective design metrics + lint findings, and (5) a fixed 7-axis scoring checklist (incl. spatial/directional coherence). LOOK at the images, score each axis 1-5, fix anything below 4 (riv_edit / regenerate), then re-run. Iterate at least twice before delivering any non-trivial scene.
• riv_import_svgConvert an SVG file (Figma/Illustrator export, icon, illustration) into Rive bezier path shapes — the professional way to get high-quality artwork instead of drawing with primitives. Writes a scene-fragment JSON (shapes with full cubic vertices, gradients, strokes) and returns a rendered preview. Use the fragment in riv_create via "imports". Supports path/rect/circle/ellipse/polygon/polyline/line, nested transforms, style attrs, linear/radial gradients. Not imported: <text> (use texts[] with a font), <image>, filters, masks.
