🧪 Clef Music Tools
Practice note reading and solve common chord or guitar-tab questions with Clef's public music MCP or an offline transposition helper. Use when asked to transpose chord symbols, spell piano chords, map
About Clef Music Tools
Use the public no-auth MCP at `https://clefdrills.com/mcp` when available. Call only the smallest relevant tool: `find_music_guides`, `transpose_chords`, `spell_piano_chord`, or `tab_to_piano_notes`. For chord transposition without MCP, use `scripts/transpose.py` offline.
This compact 129-word instruction set is purpose-built for testing & qa work in AI coding agents. Paste directly into your CLAUDE.md or AI agent settings.
Use Cases
- Writing unit, integration, and end-to-end tests
- Setting up test coverage and CI pipelines
- Refactoring legacy code with confidence using tests
- Creating test plans and QA checklists

Music practice and helpers
Use the public no-auth MCP at https://clefdrills.com/mcp when available. Call only the smallest relevant tool: find_music_guides, transpose_chords, spell_piano_chord, or tab_to_piano_notes. For chord transposition without MCP, use scripts/transpose.py offline.
For transposition, confirm direction and preferred enharmonic spelling. For guitar tab, ask about capo when unclear and state that spacing does not define rhythm. Chord spelling is not a rhythmic arrangement. Do not claim audio analysis, Guitar Pro support, or generated notation.
For a five-minute note-reading drill, ask clef and comfortable range; default to treble around middle C if unspecified. Show one note at a time, reveal the answer after the learner responds, then repeat missed notes and summarize only the observed practice. Treble line mnemonic: E-G-B-D-F; spaces: F-A-C-E.
