Overview

AI-generated overview

Remote MCP server that lets an assistant transpose chords, spell piano chords, convert guitar tab to piano notes, and find music guides.

What you can do
  • Transpose chord symbols, including slash bass notes
  • Spell a supported chord as piano pitches with octave and MIDI values
  • Convert six-string ASCII guitar tab into sounding piano pitches
  • Find Clef instructional guides by words in the title and description
When to use it
Useful when working with chord charts, songwriting or music theory: shifting a progression to another key, checking how a chord lays out on the piano, or turning a simple text tab into piano notes. Also handy for locating Clef's own instructional guides.
Requirements
A remote streamable HTTP endpoint at clefdrills.com; no packages, environment variables, headers or authentication are declared.
Before you install
The tools are narrow: guides are not file converters, transposition does not handle audio, lyrics or notation files, chord spelling does not produce rhythmic arrangements, and tab spacing does not define note duration. No GP files or audio uploads are supported.

Installation

In SourceWeft

  1. Open Clef Music Tools in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.MelMayssonOwen%2Fclef-music-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
