Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 1456 tokens (~69/item across 21 items; 5 tools + 16 resources), lean.Pass
- 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
- Supports UI / widget rendering.Pass

get-music-guide Music Reference Guide ~120
Returns detailed reference material for music composition. Topics: instruments (GM instrument list + combos), drums (patterns + percussion notes), abc-syntax (notation reference), arrangements (multi-voice patterns), genres (complete ABC templates for jazz/blues/folk/rock/bossa/classical), styles (what each style preset does), midi-directives (%%MIDI reference).
| Name | Type | Req | Description |
|---|---|---|---|
| topic | string | yes | Reference topic. Start with 'genres' for complete examples, 'styles' to understand presets, or 'instruments' for the full instrument list. |
No output schema declared.
No examples provided.
get-strudel-guide Strudel Reference Guide ~163
Reference material for Strudel live coding (performance mode). Topics: mini-notation (pattern syntax), sounds (synths, 72 drum banks, 128 GM instruments), effects (filters, reverb, delay, FM synthesis, envelopes), patterns (transformations, probability, euclidean, arrangement), genres (complete templates: techno/house/dnb/ambient/jazz/lofi/synthwave), tips (tempo, common mistakes, ABC↔Strudel crossover), advanced (visualization, sample loading, wavetables, ZZFX, continuous signals, chord voicings).
| Name | Type | Req | Description |
|---|---|---|---|
| topic | string | yes | Reference topic. Start with 'genres' for working templates, 'sounds' for instruments, 'advanced' for visualization and sample loading. |
No output schema declared.
No examples provided.
play-live-pattern Play Live Pattern ~277
Live-code music patterns using TidalCycles mini-notation in JavaScript. Layer drums, synths, and bass with stack(). Choose from 72 drum machine banks, 128 GM instruments, built-in synths, and a full effects chain. Patterns play in a REPL the user can edit directly. Add .pianoroll() to a pattern to show a live piano-roll animation in the widget (or .punchcard()/.scope()/.spectrum() — use one visual per pattern). Use get-strudel-guide for genre templates, sound references, and advanced features like visualization, arrangement, and sample loading. The Strudel REPL renders inline with an editable code editor, visualizations, and playback controls.
| Name | Type | Req | Description |
|---|---|---|---|
| autoplay | boolean | — | Start playing immediately (default: true). May require user click due to browser autoplay policy. |
| bpm | number | — | Tempo in BPM (40-300). Converts to setcps() automatically. |
| code | string | yes | Strudel pattern code. Uses TidalCycles mini-notation in JavaScript. Use stack() to layer drums, bass, and melody. Set tempo with setcps(bpm/60/4) or use the bpm parameter. |
| title | string | — | Pattern title displayed in the widget header (e.g. 'Midnight Rain'). |
No output schema declared.
No examples provided.
play-sheet-music Play Sheet Music ~359
Compose and play sheet music with visual notation, multi-instrument audio, and style presets. Write ABC notation for melodies, arrangements, harmonized pieces, or well-known tunes. Add a style (rock, jazz, bossa, waltz, folk...) for automatic drums, bass, and chord accompaniment. Returns a parse-status confirmation and renders the player; it does not return raw audio. Use get-music-guide for genre templates, instrument lists, and ABC syntax reference. The music player renders inline with interactive playback controls.
| Name | Type | Req | Description |
|---|---|---|---|
| abcNotation | string | — | ABC notation string. Include chord symbols ("C", "Am7") above notes for auto-accompaniment with style presets. |
| instrument | string | — | Default instrument (e.g. 'Flute', 'Cello', 'Acoustic Grand Piano', 'Alto Sax'). Use get-music-guide with topic 'instruments' for the full list. |
| style | string | — | Accompaniment style. Adds drums, bass, and chord patterns automatically. Your ABC needs chord symbols ("C", "Am") for accompaniment to work. Options: rock, jazz, bossa, waltz, march, reggae, folk, cl… |
| swing | number | — | Swing percentage (0-100). 0=straight, 33=light swing, 66=heavy swing. Great for jazz and blues. |
| tempo | number | — | Tempo in BPM (40-240). Overrides Q: in ABC notation. |
| title | string | — | Piece title (overrides T: in ABC). Displayed in the widget header. |
| transpose | number | — | Transpose by semitones (-12 to 12). Positive=higher, negative=lower. |

No examples provided.
search-music-docs Search Music Documentation ~160
Search detailed documentation for Strudel live coding or ABC/ABCJS notation. Returns relevant code examples and explanations from the official docs. Use this when the curated guides (get-strudel-guide, get-music-guide) don't cover what you need — for specific functions, advanced techniques, or when you're unsure about syntax. Powered by semantic search over strudel.cc and ABCJS docs.
| Name | Type | Req | Description |
|---|---|---|---|
| library | string | — | Which library to search: 'strudel' for live coding patterns, 'abcjs' for sheet music notation. |
| query | string | yes | What you want to know. Be specific. Good: 'how to use FM synthesis with envelope' or 'chop and slice sample manipulation'. Bad: 'effects' or 'help'. |
