### Deterministic Music Theory for Claude, Cursor, and Autonomous AI Agents Large Language Models (LLMs) frequently hallucinate music theory, leading to incorrect notes, false Roman numerals, and broken voice leading. **THIRI** solves this by providing a deterministic, mathematical music-theory engine (pitch-class-set theory over ℤ/12) directly to your AI. It gives AI assistants precise, reproducible harmonic reasoning in milliseconds, allowing them to write correct musical scores, analyze progressions, and generate playable arrangements. #### 🎷 Key Features: * **Chord Analysis (`analyze_chord`):** Parse any symbol (e.g., `Cmaj7/E`, `G7#11`) to retrieve root, quality, intervals, Roman numerals, and diatonic or chromatic harmonic functions. * **Note Resolution (`resolve_chord`):** Resolve chord symbols to spelled notes (enharmonically correct), frequencies (Hz), MIDI numbers, and scale recommendations. * **Voicing Engine (`generate_voicing`):** Generate instrument-ready voicings (rootless, shell, triad, pad, drop-2, drop-3) and calculate voice-leading scores for transitions. * **Reharmonization (`reharmonize`):** Substitute progressions using classic jazz techniques, including Tritone Substitution, ii-V Insertion, Modal Interchange, Coltrane Changes, and Backdoor cadences. *Ideal for developers building AI music assistants, digital audio workstation (DAW) agents, educational theory tools, and automated composition workflows.*

AutoSearch exposes a complete systematic-review pipeline as 6 MCP tools — not a thin search wrapper. `autosearch_run_research` launches an async PRISMA 2020 run (multi-source academic search across OpenAlex, Crossref, PubMed, Semantic Scholar, arXiv, ClinicalTrials.gov, DBLP and DOAJ; screening with recorded inclusion/exclusion decisions; evidence synthesis; IMRAD paper with APA references and PRISMA flow counts). Companion tools poll status, fetch the finished paper (markdown/JSON/PDF), verify any DOI live against Crossref, run one-shot evidence searches, and list runs. Citations are verified by construction: every DOI is checked against the Crossref API before it enters a deliverable, and a re-runnable citation-integrity benchmark is published at https://exatoshi.uk/trust (latest: 99/99 DOIs resolved, 0 fabricated, across 23 real deliverables — failures would be published too). Auth is a single `x-api-key` header; free account includes 50 credits. Docs with schemas, JSON examples and credit costs: https://exatoshi.uk/developers
