// key findings
⚠️
Known vulnerabilities in dependencies: 4 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README

// tools this server exposes8 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

tidal_eval

Evaluate a TidalCycles pattern on a specific channel (d1-d9). This is the main way to make music with Tidal.

tidal_hush

Stop all currently playing patterns immediately. Use this to clear everything.

tidal_silence

Stop a specific channel. More graceful than hush for single channels.

tidal_get_state

Get the current state of all channels - what patterns are playing and when they started.

tidal_solo

Solo a specific channel, muting all others temporarily.

tidal_unsolo

Restore all channels after soloing.

tidal_get_history

Get the history of patterns evaluated in this session.

tidal_get_samples

Get list of available sample names from Dirt-Samples folder.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

8/8 tools missing one or more hints — tidal_eval (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tidal_hush (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tidal_silence (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.20.2 (high), @modelcontextprotocol/sdk@1.20.2 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
