Connect THIRI Chord Intelligence and your agent gets 5 tools, among them analyze_chord, conduct_band, generate_voicing. It answers at https://mcp.thiri.ai/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Deterministic music theory for agents: analyze, voice, reharmonize, conduct — computed, not guessed
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
analyze_chord | Parse a chord into root, quality, intervals, and (with a key) roman numeral + function. Inputs: chord, key |
conduct_band | Arrange a 4-piece band from a natural-language prompt. Returns conductor tempo/groove, 4 lanes of note events, lead sheet, and base64 MIDI. Audio render (Csound → WAV) stays on local thiri-conductor-mcp / POST /v2/render. Inputs: prompt, durationSec |
generate_voicing | Instrument-ready voicing in a style. Tension symbols voice by seat substitution (arranging practice, not stacking): 9/b9/#9 replace the root, #11/13/b13 replace the 5th, the 3rd and 7th are untouched guide tones. Pass voices: 5 to promote t Inputs: chord, style, octave, voices, previousNotes, keyContext |
reharmonize | Reharmonize a progression. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_changes, backdoor (or auto). Inputs: progression, technique, key |
resolve_chord | Resolve a chord to spelled notes, frequencies, MIDI, and recommended scales. Inputs: chord |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.thiri.ai/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: ai.thiri. Endpoint host: mcp.thiri.ai. ARD identifier: urn:air:ai.thiri:mcp:chord-intelligence.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
