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 → Why this is hard to score →
Supply Chain Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 4 of 68 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to raulkivi/sheet-music-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 4 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 386 tokens (~55/item across 7 items; 7 tools + 0 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_recording ~84
Analyse a pre-recorded WAV file against a reference score. Returns per-note pitch accuracy and a summary histogram.
| Name | Type | Req | Description |
|---|---|---|---|
| audio_path | string | yes | Absolute path to a 16-bit PCM WAV file |
| musicxml | string | yes | MusicXML document as a string |
| part_id | string | yes | Part ID to compare against (e.g. 'Soprano') |
No output schema declared.
No examples provided.
get_current_position ~44
Poll the current score position and pitch accuracy. Call repeatedly while monitoring. Returns measure, beat, and accuracy.
| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | Session ID from load_score |
No output schema declared.
No examples provided.
health_check ~72
Check that all runtime dependencies are available and report their status. Use this to verify the server is set up correctly. Returns status for offline analysis (librosa/pYIN) and real-time monitoring (sounddevice/portaudio). Missing portaudio is a warning, not an error — offline analysis still works without it.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_capabilities ~22
List supported formats, tools, and backend information for this server
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.

Load a reference MusicXML score into a named session. Returns a session_id to use with start_monitoring.
| Name | Type | Req | Description |
|---|---|---|---|
| musicxml | string | yes | MusicXML document as a string |
| part_id | string | yes | Part ID to monitor (e.g. 'Soprano') |

| Name | Type | Req | Description |
|---|---|---|---|
| session_id | string | yes | Session ID from load_score |
| tempo_bpm | integer | – | Override tempo in BPM (default: score tempo) |
No output schema declared.
No examples provided.
stop_monitoring ~40
Stop the microphone and return a session summary. The session is cleaned up after this call.
