## Findings

- **warn** Annotations that disagree with the tool in `generate_cyclic_scales` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_cyclic_scales" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "generate_cyclic_scales" says "generate": a word for a change.
```


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_equal_division_frequency`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to calculate one deterministic frequency in an equal division of the octave with an optional concert-root transposition. Do not infer ownership, licensing, or unpublished availability.
```

### `classify_cyclic_mode`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to classify one bounded cyclic mode by acting group: its rotation, reversal, and set classes; transposition-symmetry kernel; reflection structure; interval and Fourier content; evenness and generation; and every direct-sum factorization. Do not infer ownership, licensing, or unpublished availability.
```

### `export_cyclic_scale_musicxml`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to create a bounded, two-measure MusicXML representation of a 12-division cyclic scale for local import, in the mixed, sharp, or flat accidental spelling. Do not infer ownership, licensing, or unpublished availability.
```

### `generate_cyclic_scales`

- The name "generate_cyclic_scales" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to generate at most 24 canonical cyclic interval words under bounded equal-division, cardinality, interval, reflection, and transpositional-symmetry constraints. Do not infer ownership, licensing, or unpublished availability.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `analyze_cyclic_scale`

- The name "analyze_cyclic_scale" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to analyze one bounded cyclic interval word, including its pitch path, rotations, reversal partners, reflection class, and limited-transposition status. Do not infer ownership, licensing, or unpublished availability.
```

### `get_composition`

- The name "get_composition" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to get public recordings matching a composition title. Do not infer ownership, licensing, or unpublished availability.
```

### `get_release`

- The name "get_release" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to get one public release by slug. Do not infer ownership, licensing, or unpublished availability.
```

### `get_sheet_music`

- The name "get_sheet_music" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to check for an explicitly published sheet-music resource. Never infers rights or availability. Do not infer ownership, licensing, or unpublished availability.
```

### `get_track`

- The name "get_track" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to get one public track by blob identifier or title. Do not infer ownership, licensing, or unpublished availability.
```

### `list_releases`

- The name "list_releases" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to list public album and release records. Do not infer ownership, licensing, or unpublished availability.
```

### `search_music`

- The name "search_music" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent needs to search the public music catalog. Do not infer ownership, licensing, or unpublished availability.
```
