The Tools

Every tool is read-only and stateless: every caller gets the same answer to the same question. This list is generated from the endpoint’s own tool registry, so it names exactly what the endpoint serves.

• list_instruments() — List every instrument this server has chord and tuning data for — id, display label, family, tuning (open-string notes low to high) and a link to its chord library.
• list_chord_qualities(instrument) — List every chord quality (major, m7, dom7, sus4, add9, ...) this instrument actually has voicings for, with a display label and, where the label differs meaningfully from the id, a common alias (e.g. "dom7" aliases "7").
• list_scale_types() — List all 24 scale types this server knows — id, display label, category (Common, Pentatonic, Blues, Modes, Bebop, Symmetric), interval formula (semitones from the root), and, for scales that are also a mode of the major scale, its common alias.
• get_tuning(instrument, variant?) — Look up one instrument's open-string tuning, low to high.
• get_chord(instrument, root, quality, position?) — Look up every voicing this server has for one chord on one instrument — frets (low string first, null = muted, 0 = open; each is the fret the player stops that string at, so the 5-string banjo's short fifth string reads from fret 6 up), base fret (the library's own position band, which "position" filters on; the diagram on the page may open its window elsewhere), CAGED shape where applicable, and the actual notes/interval degrees sounded by that specific voicing (not just the chord's theoretical tone set).
• get_scale(instrument?, root, scale_type) — Look up one scale's notes and interval formula in a given key, degree-spelled (e.g. Lydian's raised 4th reads "#4", not "b5").
• transpose_chord(name, semitones) — Transpose one chord symbol by a number of semitones.
• transpose_progression(chords, from_key, to_key) — Transpose a whole chord progression from one key to another in one call — every chord shifts by the same interval.
• get_page_url(topic, instrument, key?, quality?) — Build (and check the existence of) the canonical URL for a chord, scale or instrument page — absolute, on the Warrior Network site that is home to the instrument's family, or otherwise on the network's hub, https://stringwarrior.com — so you can cite a source without guessing at path spelling or at which site to name.
