# Resolume MCP Server
[](https://www.npmjs.com/package/resolume-mcp-server)
[](LICENSE)
Control [Resolume Arena/Avenue](https://resolume.com/) from AI assistants like Claude using the [Model Context Protocol](https://modelcontextprotocol.io). Trigger clips, fade layers, and pull thumbnails — all through natural language.

## Why this server?
Three other Resolume MCP servers exist; this one focuses on a **deliberate middle ground**:
- **Curated tool count** — every tool earns its place. Wide-net registries (200+ tools) confuse the model.
- **Type-safe end to end** — Zod schemas on every input, structured errors with recovery hints the LLM can act on.
- **Visual identification** — `resolume_get_clip_thumbnail` returns the actual image, so Claude can pick the right visual when names are ambiguous.
- **Destructive-action gating** — `clear_layer` requires explicit `confirm: true` to prevent accidental wipes during live performance.
- **Helpful errors** — every error variant carries a `hint` field telling the LLM what to do next ("Resolume not running — ask the user to launch it and enable the Webserver").
- **Push-driven cache** *(v0.5+)* — opt-in `CompositionStore` consumes Resolume's OSC OUT broadcast (~325 msg/s) so high-frequency reads (clip playhead, BPM, layer opacity) don't pay a REST round-trip.
- **Stability tiers** *(v0.5+)* — every tool carries `stability: stable | beta | alpha`; the `RESOLUME_TOOLS_STABILITY` env filter lets risk-averse operators hide unstable tools.
- **Live-tested** — every release verified end-to-end against a real Resolume Arena 7.23. Silent no-ops, wire encoding regressions, and Resolume internals (effect-id re-keying after PUTs, double-broadcast of UI-bound parameters) are documented in `docs/v0.5/`.
## Requirements
- **Node.js 20+**
- **Resolume Arena 7.8+** or **Avenue 7.8+** with the Web Server enabled:
1. Open Resolume → `Preferences` → `Web Server`
2. Toggle **Enable Webserver & REST API** on
3. Default port is `8080` (Arena/Avenue) or `8081` (Wire)
## Install
```bash
npm install -g resolume-mcp-server
```
Or run without global install via `npx`:
```bash
npx resolume-mcp-server
```
## Configure for Claude
### Claude Desktop
Add to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"resolume": {
"command": "npx",
"args": ["-y", "resolume-mcp-server"],
"env": {
"RESOLUME_HOST": "127.0.0.1",
"RESOLUME_PORT": "8080"
}
}
}
}
```
### Claude Code
Add to `.mcp.json` in your project root:
```json
{
"mcpServers": {
"resolume": {
"command": "npx",
"args": ["-y", "resolume-mcp-server"]
}
}
}
```
### Environment variables
#### Core (always relevant)
| Variable | Default | Description |
|----------|---------|-------------|
| `RESOLUME_HOST` | `127.0.0.1` | Host running Resolume's Web Server |
| `RESOLUME_PORT` | `8080` | Web Server port (8080 Arena/Avenue, 8081 Wire) |
| `RESOLUME_TIMEOUT_MS` | `10000` | Per-request timeout in milliseconds |
| `RESOLUME_OSC_HOST` | `127.0.0.1` | Host running Resolume's OSC ports (same as REST host in most setups) |
| `RESOLUME_OSC_IN_PORT` | `7000` | Resolume's OSC IN port — we send to this |
| `RESOLUME_OSC_OUT_PORT` | `7001` | Resolume's OSC OUT port — we listen on this for queries/subscriptions |
#### v0.5+ feature flags (all opt-in; defaults reproduce v0.4 behavior bit-for-bit)
| Variable | Values | Default | Description |
|----------|--------|---------|-------------|
| `RESOLUME_CACHE` | empty / `0` / `1` / `owner` / `passive` / `shared` | empty (off) | Enables the in-memory `CompositionStore` cache fed by Resolume's OSC OUT broadcast. `1` / `owner` binds the OSC OUT port exclusively; `passive` / `shared` lets other tools feed the cache via `feed()`. EADDRINUSE on `owner` bind auto-degrades to `shared` mode with a stderr warning. |
| `RESOLUME_EFFECT_CACHE` | `0` / `1` / `true` / `false` | `1` (on) | Effect-id cache for `setEffectParameter`. Single-flight on concurrent calls; layer-wide invalidation on add/remove/wipe/deck-switch. Set to `0` to bisect drift bugs. |
| `RESOLUME_TOOLS_STABILITY` | `stable` / `beta` / `alpha` | `beta` | Tool tier visibility filter. `stable` hides beta+alpha tools; `alpha` exposes everything (operator escape hatches like `resolume_cache_refresh`). |
| `RESOLUME_WIPE_CONCURRENCY` | `1`..`16` | `4` | Per-layer parallel POST cap for `wipeComposition`'s `/clearclips` dispatch. Conservative default keeps Resolume's single-threaded HTTP server happy. |
## Tools (v0.5.4 — 39 tools)
All tools are prefixed with `resolume_` to avoid collision with other MCP servers. Indices are **1-based** to match Resolume's UI. Every tool carries an explicit `stability` tier; `tools/list` decorates the description with `[BETA]` / `[ALPHA]` prefixes when applicable, and the `RESOLUME_TOOLS_STABILITY` env var filters what's exposed (default `beta` shows stable+beta, `alpha` shows everything, `stable` hides everything not yet promoted).
### Composition
| Tool | What it does |
|------|--------------|
| `resolume_get_composition` | Returns version, BPM, layers (with connected clip + bypass state), columns, decks. **Call first.** |
| `resolume_get_beat_snap` | Current clip beat-snap value + available options (None, 1 Bar, 1/2 Bar, etc.). |
| `resolume_set_beat_snap` | Sets clip beat-snap. Triggered clips wait for the next beat boundary — the core BPM-sync mechanism. |
| `resolume_get_crossfader` / `resolume_set_crossfader` | Master A/B crossfader. -1 = full Side A, 0 = center, 1 = full Side B. |
### Clips
| Tool | What it does |
|------|--------------|
| `resolume_trigger_clip` | Plays the clip at `{layer, clip}` — the most common VJ action. |
| `resolume_select_clip` | Selects without playing. Useful before adjusting parameters. |
| `resolume_get_clip_thumbnail` | Returns the clip's preview image inline so the LLM can see it. |
| `resolume_get_clip_position` *(v0.5.1+)* | Reads the normalized 0..1 transport position. Cache-first when `RESOLUME_CACHE=1` (sub-ms cache hits, no REST round-trip); REST fallback otherwise. Tagged with `source: "cache" \| "rest"`; cache hits include `ageMs`. |
| `resolume_set_clip_play_direction` | Forward (`>`) / pause (`||`) / reverse (`<`). |
| `resolume_set_clip_play_mode` | Loop / Bounce / Random / Play Once & Clear / Play Once & Hold. |
| `resolume_set_clip_position` | Seek to a specific playback position (re-trigger from start, jump to cue points). |
| `resolume_clear_clip` | **Destructive.** Empties a single clip slot (removes loaded media). Requires `confirm: true`. |
| `resolume_wipe_composition` | **Destructive.** Empties every clip slot on every layer in the active composition via per-layer `/clearclips` POSTs. Concurrency cap configurable via `RESOLUME_WIPE_CONCURRENCY`. Requires `confirm: true`. |
### Layers
| Tool | What it does |
|------|--------------|
| `resolume_set_layer_opacity` | Fades a layer (`opacity` in 0..1). Smooth fades = multiple small steps. |
| `resolume_set_layer_bypass` | Mutes/unmutes a layer without losing the connected clip. |
| `resolume_set_layer_blend_mode` | Changes layer blend mode (Add, Multiply, Screen, etc.). |
| `resolume_list_layer_blend_modes` | Lists the 60+ blend modes available. |
| `resolume_set_layer_transition_duration` | Per-layer transition fade duration (0..10s, 0 = instant cut). |
| `resolume_set_layer_transition_blend_mode` / `resolume_list_layer_transition_blend_modes` | Visual transition effect (Alpha, Wipe Ellipse, Push Up, ...). 50+ options. |
| `resolume_clear_layer` | **Destructive.** Disconnects all clips. Requires `confirm: true`. |
### Columns / Decks
| Tool | What it does |
|------|--------------|
| `resolume_trigger_column` | Fires every clip in a column simultaneously — standard scene change. |
| `resolume_select_deck` | Switches deck (scene bank). |
### Tempo
| Tool | What it does |
|------|--------------|
| `resolume_get_tempo` | Returns current BPM and the accepted range (typically 20..500). |
| `resolume_set_bpm` | Sets exact BPM (e.g., for synced sets). |
| `resolume_tap_tempo` *(beta)* | Sends taps to the tap-tempo controller (single tap or multi-tap with interval). |
| `resolume_resync_tempo` | Sends a resync trigger to align Resolume's beat clock to the next downbeat. |
### Effects
| Tool | What it does |
|------|--------------|
| `resolume_list_video_effects` | ~105 video effects available globally, with `idstring` + `name`. |
| `resolume_list_layer_effects` | Effects on a layer with full parameter metadata: type, current value, min/max, and choice options. |
| `resolume_set_effect_parameter` | Mutates any parameter on an attached effect. Auto-coerces string-encoded numbers/booleans to match the parameter's declared type. |
| `resolume_add_effect_to_layer` | Adds a video effect by name to the end of a layer's effect chain. |
| `resolume_remove_effect_from_layer` | Removes the effect at a 1-based position. **Destructive** — requires `confirm: true`. |
### OSC (v0.4)
OSC complements REST/WS with a few things they can't do: wildcard reads, real-time playhead push, and a handful of trigger paths not in the REST swagger. Requires Resolume's `Preferences > OSC > OSC Input/Output` to be enabled.
| Tool | What it does |
|------|--------------|
| `resolume_osc_send` | One-shot OSC message. Power-user escape hatch for paths like `/composition/tempocontroller/resync`. |
| `resolume_osc_query` | Sends `?` query (with optional wildcards) and returns Resolume's echoed values. Fastest way to read many values at once. |
| `resolume_osc_subscribe` | Listens on the OSC OUT port for a duration and collects messages matching a glob pattern. Use `/composition/layers/*/clips/*/transport/position` for real-time clip-playhead tracking (~325 msg/s). When `RESOLUME_CACHE` is enabled, transparently multiplexes through the store (no `EADDRINUSE`). ⚠️ `*` is segment-bound (OSC 1.0): `/a/*/b` works, `/a/*` won't match `/a/b/c`. Playhead values are normalized 0..1. **Pass `dedupe: true`** *(v0.5.4+)* to collapse Resolume's wire-level double-broadcast on UI-bound parameters (notably `/composition/layers/*/position`). |
| `resolume_osc_status` | Probes whether Resolume is broadcasting on the configured OSC OUT port. |
### Cache *(v0.5.1+; gated on `RESOLUME_CACHE`)*
The `CompositionStore` is an in-memory snapshot fed by Resolume's OSC OUT broadcast (~325 msg/s). When enabled, `*Fast` read methods on `ResolumeClient` (and the `resolume_get_clip_position` tool above) consult it instead of paying a REST round-trip. With the cache off (default), every read goes to REST exactly as in v0.4.
| Tool | What it does |
|------|--------------|
| `resolume_cache_status` | Diagnostics: returns `{ enabled, mode, revision, hydrated, oscLive, msgsReceived, lastOscAt, lastSeedAt, ... }`. Read-only. Use to verify the cache is receiving OSC pushes after enabling `RESOLUME_CACHE`. |
| `resolume_cache_refresh` *(alpha — hidden by default)* | Operator escape hatch: forces a full REST re-seed. Rate-limited to one call per 500 ms. Set `RESOLUME_TOOLS_STABILITY=alpha` to expose; intended for recovery (after Resolume restart, or when `cache_status` shows `oscLive=false` despite Resolume running). |
## Example prompts
> "What's the current state of the composition?"
> "Trigger clip 3 on layer 2."
> "Fade layer 1 down to 0 over a few steps."
> "Show me the thumbnail for layer 1 clip 4 — is that the right one for the chorus?"
> "Clear layer 2." (Claude will ask for confirmation before sending `confirm: true`.)
## Bundled Skill
A Claude Code [skill](https://docs.claude.com/en/docs/claude-code/skills) ships in this repo at [`skills/resolume-mcp-tester/`](./skills/resolume-mcp-tester/SKILL.md). It encodes the operational knowledge accumulated across releases — smoke-test recipes, white-out prevention rules, state-restoration patterns, and agent invocation templates for verifying every tool against a live Resolume Arena.
Install once into your Claude Code skill directory:
```bash
# macOS / Linux
mkdir -p ~/.claude/skills
cp -r skills/resolume-mcp-tester ~/.claude/skills/
```
```powershell
# Windows (PowerShell)
New-Item -ItemType Directory -Force "$HOME\.claude\skills" | Out-Null
Copy-Item -Recurse -Force skills\resolume-mcp-tester "$HOME\.claude\skills\"
```
Restart Claude Code, then ask it to "run a comprehensive smoke test of resolume-mcp-server" — it'll load the skill automatically and follow the safety rules. See [`skills/README.md`](./skills/README.md) for details and the versioning policy.

cd resolume-mcp-server
npm install
npm run build
npm test
npm run test:coverage # 80%+ thresholds enforced
```
`npm install` activates local git hooks (`pre-commit` runs typecheck +
skill-sync drift check in ~3-5s; `pre-push` adds the full vitest suite).

## Known Resolume API quirks
- **Non-ASCII clip names** can break some REST endpoints — keep names ASCII when possible.
- **Some WebSocket actions don't ack** — handled with optimistic timeouts in upcoming v0.2.
- **`/product` endpoint** is recent; older Resolume versions return 404 (handled gracefully).
