Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security86
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency32
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: the license (PolyForm-Noncommercial-1.0.0) isn't a recognized OSI-approved license. See how to fix → Fail
- Actively maintained (last published 1 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
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 750 tokens (~107/item across 7 items; 5 tools + 2 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

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.
analyze_chord ~100
Parse a chord symbol into its root, quality, intervals, extensions, and harmonic function. When a key is provided, returns the Roman numeral, scale degree, and whether the chord is diatonic.
| Name | Type | Req | Description |
|---|---|---|---|
| chord | string | yes | Chord symbol (e.g. 'Dm7', 'Cmaj7/E', 'G7#11') |
| key | string | — | Key center for functional analysis (e.g. 'C', 'Bb') |
No output schema declared.
No examples provided.
conduct_band ~102
Arrange a 4-piece band from a natural-language prompt. Returns conductor tempo/groove, 4 lanes of note events, lead sheet, and base64 MIDI. Browser/client synthesizes audio via Csound; use thiri-conductor-mcp locally to render WAV.
| Name | Type | Req | Description |
|---|---|---|---|
| durationSec | number | — | Optional target duration override |
| prompt | string | yes | Musical direction (e.g. '12-second neo-soul band in Eb, Rhodes + analog bass') |
No output schema declared.
No examples provided.
generate_voicing ~250
Generate instrument-ready voicings for a chord in a specified style. Pass previousNotes (or a previousVoicing object) from an earlier result to get a voiceLeadingScore for the transition. Styles: rootless, bill_evans, shell, triad, pad, guide-tones, guide-tone-1, guide-tone-2, both-guide-tones, drop-2, drop-3.
| Name | Type | Req | Description |
|---|---|---|---|
| chord | string | yes | Chord symbol (e.g. 'Dm7') |
| colorPreferences | object | — | Explicit color-tone overrides |
| density | number | — | Target voicing density / note count hint |
| keyContext | string | — | Key context for diatonic color hooks (e.g. 'C major') |
| octave | number | — | Base octave (default: 3) |
| previousNotes | array | — | Previous voicing notes for voice leading (e.g. ['E3', 'G3', 'Bb3', 'D4']) |
| previousVoicing | — | — | Prior generate_voicing JSON result for strict guide-tone line tracking |
| style | string | — | Voicing style (default: 'pad'). bill_evans is an alias of rootless. |
No output schema declared.
No examples provided.
reharmonize ~186
Reharmonize a chord progression using jazz techniques. Returns one alternative per applicable technique, each with the new progression, the changes, and a plain-English explanation. With technique 'auto' (default) it returns every technique that applies. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_changes, backdoor. (modal_interchange and backdoor require a key.)
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | — | Key center (e.g. 'C') — enables modal_interchange and backdoor |
| progression | array | yes | Chord symbols, one per bar (e.g. ['Cmaj7', 'Dm7', 'G7', 'Cmaj7']) |
| technique | string | — | Reharmonization technique (default: 'auto' = all applicable) |
No output schema declared.
No examples provided.
resolve_chord ~54
Resolve a chord symbol to spelled note names, frequencies in Hz, MIDI numbers, and recommended improvisation scales.
| Name | Type | Req | Description |
|---|---|---|---|
| chord | string | yes | Chord symbol (e.g. 'Cm7', 'F#dim7') |
No output schema declared.
