### 2026-11-03 (score 67)

First indexed and scored.

## MCP tools (9)

### `convert` (~149 tokens)

Convert a music file

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

Returns the output path, a confidence level (exact, high, medium, low),
the share of notes kept, features the target format cannot hold, and
exporter quirks that were repaired on the way in.

Input parameters:

- `input` (string, required): Absolute path to a music file
- `output`: Output file or folder (default: next to the input)
- `to` (string, required): Target format: musicxml, mxl, midi, abc, mei, humdrum, or pdf/png/svg (sheet music) or wav (audio)

### `batch_convert` (~101 tokens)

Convert many music files

Convert files, or every score inside folders, to one format.

One failure does not stop the batch; each file gets its own row.

Input parameters:

- `inputs` (array, required): Files and/or folders
- `output_dir`: Folder for the results (default: beside each input)
- `to` (string, required): Target format: musicxml, mxl, midi, abc, mei, humdrum, or pdf/png/svg (sheet music) or wav (audio)

### `inspect` (~118 tokens)

Look at a score

Summarise a score and show some bars as ABC notation.

Gives title, composer, parts with instruments and ranges, key signature
and estimated key, meters, tempos and bar count, plus an ABC excerpt of
the requested bars to read the actual notes.

Input parameters:

- `bars`: Bars to show as ABC, e.g. "1-8" (max 32); "" for none
- `input` (string, required): Absolute path to a music file
- `parts`: Parts by number (1-based) or name; default all

### `validate` (~49 tokens)

Check a score for problems

Check a score: exporter quirks that needed repair, bars that do not
fill their time signature, and notes outside an instrument's range.

Input parameters:

- `input` (string, required): Absolute path to a music file

### `compare` (~71 tokens)

Compare two versions

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).

Input parameters:

- `a` (string, required): Absolute path to the first version
- `b` (string, required): Absolute path to the second version

### `transpose` (~140 tokens)

Transpose a score

Transpose a score by an interval, into a key, or between concert and
written pitch. Give exactly one of interval, key or pitch.

Input parameters:

- `input` (string, required): Absolute path to a music file
- `interval`: Interval ("M2", "-m3", "P5") or semitones ("2", "-3")
- `key`: Target key, e.g. "D", "Bb major", "F# minor"
- `output`: Output file or folder (default: next to the input)
- `pitch`: Switch transposing instruments to concert or written pitch
- `to`: Output format (default: same)

### `extract` (~116 tokens)

Extract parts or bars

Save chosen parts and/or bars of a score as new files.

Input parameters:

- `bars`: Bar range such as "1-8", "5" or "9-"
- `each_part` (boolean): One file per part (to make parts for players)
- `input` (string, required): Absolute path to a music file
- `output`: Output file or folder (default: next to the input)
- `parts`: Parts by number (1-based) or name; default all
- `to`: Output format (default: same)

### `render` (~116 tokens)

Render sheet music or audio

Engrave sheet music to print or view (PDF, PNG, SVG) or make an audio
preview (WAV) so the user can see, play or hear the score.

Input parameters:

- `input` (string, required): Absolute path to a music file
- `output`: Output file or folder (default: next to the input)
- `page_size` (string): Paper size for pdf and png
- `to` (string): pdf: printable sheet music; png: page images; svg: pages for screens; wav: audio preview

### `list_formats` (~22 tokens)

List supported formats

Formats Scoreproof reads and writes, and what each one cannot hold.

## Common questions

### 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 83 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.
