Category Design and Media
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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 3 of 60 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to asampat3090/scoreproof). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- 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 Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 1161 tokens (~105/item across 11 items; 9 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
batch_convert Convert many music files ~101
Convert files, or every score inside folders, to one format. One failure does not stop the batch; each file gets its own row.
| Name | Type | Req | Description |
|---|---|---|---|
| inputs | array | yes | Files and/or folders |
| output_dir | – | – | Folder for the results (default: beside each input) |
| to | string | yes | Target format: musicxml, mxl, midi, abc, mei, humdrum, or pdf/png/svg (sheet music) or wav (audio) |
Structured output declared, but exposes no named fields.
No examples provided.
compare Compare two versions ~71
Show what changed between two versions of a piece, bar by bar. The files may be in different formats (e.g. an original MusicXML and a MIDI export of it).

convert Convert a music file ~149
Convert a score between formats and verify the result note by note, or turn it into sheet music (pdf, png, svg) or audio (wav).

What is the Scoreproof MCP server?
Scoreproof is an MCP server listed in the public MCP registry as io.github.asampat3090/scoreproof. Convert MusicXML, MIDI, ABC, MEI and Humdrum, print sheet music, and verify every note survived. This page covers its PyPI package (scoreproof).
Is the Scoreproof MCP server safe to use?
Scoreproof scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Scoreproof MCP server expose?
Scoreproof exposes 9 tools: convert, batch_convert, inspect, validate, compare, and 4 more. Their descriptions and schemas cost roughly 882 tokens of context every time the server is loaded.
Is the Scoreproof MCP server still maintained?
Scoreproof is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Scoreproof MCP server under?
Scoreproof declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
