## Findings

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

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

annotations: {"readOnlyHint":true}; The name "generate_code" says "generate": a word for a change.
```


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `update_scene`

- The name "update_scene" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replace the content of one of your scenes (full scene JSON, validated first) — the edit loop for iterating instead of duplicating. Live previews watching the scene update in place. Requires an API key; own scenes only.
```

## Changes things (3)

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

### `create_scene`

- The name "create_scene" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Save a scene and get an editor URL where it opens in the visual editor (timeline, canvas, node graphs, mobile QR preview). Validates first. Works without a key: the scene is then a public 24-hour guest scene with a scannable QR, kept forever by signing up (free) and pressing Remix. With a key it saves to the account (free accounts up to the free scene limit, paid unlimited).
```

### `generate_code`

- The name "generate_code" 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
Compile a scene into a runnable React Native component. Pass inline scene JSON or a scene_id from your account. Output targets Reanimated v4 by default ("animated" targets the RN core Animated API, reduced feature set). Deterministic — no AI, no credits. Requires an API key on a paid plan.
```

### `sample_scene`

- 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
Numerically preview a scene: evaluates keyframes AND node graphs at N evenly spaced times and returns each moving prop as a value series (the same math the editor preview runs). validate_scene checks structure — this checks MOTION: confirm ranges, spring overshoot, stagger offsets, and that elements actually move before create_scene. Free to call — iterate: author → sample → adjust.
```

## Only reads (7)

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

### `get_preview_qr`

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

Description, as the server wrote it:

```untrusted-server-text
A terminal-scannable QR code for a scene. Scan it with a phone camera and the scene runs live in the Keyframer preview app on real hardware — edits sync as they happen. Public scenes (including guest scenes) work without a key; private scenes need an API key on a paid plan.
```

### `get_recipe`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one recipe by slug: metadata, the scene JSON (usable as a starting point for create_scene), and the generated React Native Reanimated component code. Recipe code is free to use.
```

### `get_scene`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch one of your scenes (or any public scene) as JSON — edit it and re-save with update_scene, or feed it to generate_code. Requires an API key.
```

### `get_scene_format`

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

Description, as the server wrote it:

```untrusted-server-text
The Keyframer scene JSON format — read this before authoring a scene. Section "scene" covers elements/keyframes/easing; section "nodes" covers node graphs (procedural animation: clocks, springs, repeaters) with the full node-type schema.
```

### `list_scenes`

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

Description, as the server wrote it:

```untrusted-server-text
List the scenes in the connected Keyframer account (id, name, updated, visibility). Requires an API key.
```

### `search_recipes`

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

Description, as the server wrote it:

```untrusted-server-text
Search 150+ free Keyframer recipes (bounce, carousels, progress rings, particles, text effects, shaders, scroll animations…). Each recipe has a scene + verified React Native Reanimated code. Returns slugs for get_recipe.
```

### `validate_scene`

- The name "validate_scene" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate a scene against the Keyframer format before create_scene or generate_code. Returns errors (must fix) and warnings (advisory). Free to call — iterate until clean.
```
