## Security scan

- **Status:** clean
- **Scanned:** 2026-09-05T15:33:34.914Z
- **Version scanned:** live
- **CVEs:** no coverage — this entry has no package coordinates to query OSV against, so "no known CVEs" is NOT asserted for it.

## Tools

5 declared. Observed from a live `tools/list` probe.
- `analyze_chord` — Parse a chord into root, quality, intervals, and (with a key) roman numeral + function.
- `resolve_chord` — Resolve a chord to spelled notes, frequencies, MIDI, and recommended scales.
- `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
- `reharmonize` — Reharmonize a progression. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_chan
- `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

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"chord-intelligence\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp.thiri.ai/mcp\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
