Voice To Instrument — Music Utilities
LocalAbout Voice To Instrument — Music Utilities
Voice To Instrument — Music Utilities is an offline MCP server for music timing and pitch calculations. It serves users who need note durations, frequencies, or note mappings; it does not generate or convert audio.
Key features
- 01Convert BPM into note durations and bar length
- 02Convert note names into frequency and MIDI number
- 03Map frequency to a note and cents deviation
- 04Run locally without network or credentials
Use cases
- 01Calculate note timing and phrase length from BPM
- 02Look up frequency and MIDI number for a note
- 03Identify the nearest note and cents deviation
MCP support
The MCP server exposes tools for timing calculations and conversions between note names and frequencies.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project READMEOffline MCP tools
Two small MCP servers for music timing and Tesla wrap preparation. Every tool runs locally using arithmetic or bundled reference data. No API key, account, network request, telemetry or website backend connection is required.
Voice To Instrument — Music Utilities
From Voice To Instrument.
tempo_to_timing: quarter-note BPM to note durations and bar length.note_to_frequency: scientific pitch notation to Hz and MIDI number.frequency_to_note: nearest equal-tempered note and cents deviation.
For example, 120 BPM gives a 500 ms quarter note, a 375 ms dotted eighth and an 8-second four-bar phrase in 4/4. A4 is 440 Hz with the default tuning. This package performs music calculations; it does not generate or convert audio.
Tesla Wrap Generator — Template Utilities
From Tesla Wrap Generator.
list_vehicle_templates: filter 12 bundled model/trim templates by family.validate_wrap_metadata: check dimensions, filename and byte size supplied by the caller against the selected template.
The catalog references Tesla's published templates, checked on October 17, 2026. The native Cybertruck template is 1024 × 768; the other bundled templates are 1024 × 1024. Reference links are returned as text and are never downloaded by the server. No template images are bundled.
Checks use conservative limits of 1,000,000 bytes and a 30-character filename
including .png. They check supplied metadata only, not file contents,
panel alignment or acceptance by a particular vehicle/software version.
This package does not generate wraps. It is not affiliated with Tesla, Inc.
Install
Download the appropriate .mcpb file from Releases
and install it in a client supporting MCP bundles. Node.js 20.19+ is required.
No environment variables or credentials are needed.
For a client configured using JSON, extract the bundle (it is a ZIP archive)
and use the absolute path to its server/index.cjs:
{
"mcpServers": {
"music-utilities": {
"command": "node",
"args": ["/absolute/path/to/extracted/voice/server/index.cjs"]
},
"wrap-utilities": {
"command": "node",
"args": ["/absolute/path/to/extracted/tesla/server/index.cjs"]
}
}
}
Development
npm ci
npm test
npm run build
npm run smoke
The smoke test connects through the MCP client SDK and calls every tool in each extracted bundle. On macOS the child servers run with OS-level network access denied. Bundle hashes and Registry metadata are generated by the build.
Registry identifiers:
io.github.stark-ydq/voicetoinstrumentio.github.stark-ydq/teslawrapgenerator

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
