## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_markup`

- 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
Checks HTML or JSX: classes that do not exist, variant classes, data-* values a class does not react to, utility classes, misuse of data-theme or data-mode, and in style attributes, <style> blocks and utility classes (bg-[#fafafa]) hand-written colors, spacing written by hand instead of the --ml-space-* scale, overridden theme tokens and text faded with opacity. Each issue names its line. Run it on markup you wrote before finishing: pass the whole page or file, <style> blocks included, not an excerpt, since it only checks what it is given.
```

### `check_render`

- 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
Checks A2UI messages (createSurface, updateComponents, updateDataModel, deleteSurface) against the Mlola Render catalog before they render: components and props that do not exist, values a component does not offer, colors or styles set by hand, fields and controls without a name, a missing root, children that do not exist or form a loop, headings that skip a level, values outside a range. Each error names its JSON Pointer path and the fix. Pass every message of the surface: one object, an array, or JSON Lines.
```

## Only reads (7)

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

### `get_component`

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

Description, as the server wrote it:

```untrusted-server-text
Everything needed to use one item: import, every prop with fixed values (variant, tone, size, side…) and its default, the classes it styles and the data-* values each reacts to, dependencies and the install command. Set include_source to read a free component's source.
```

### `get_design_rules`

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

Description, as the server wrote it:

```untrusted-server-text
The rules for building UI with Mlola: compose first, color by role, measure with the scales, shared state words, touch and focus. Read once before writing UI.
```

### `get_install_command`

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

Description, as the server wrote it:

```untrusted-server-text
How to set Mlola up: the commands to run in a project to add components, blocks, pages or templates (with the license step for Mlola Pro items), and the stylesheet link and script for a page with no build step. Leave names out for the setup alone.
```

### `get_render_catalog`

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

Description, as the server wrote it:

```untrusted-server-text
The components an agent may compose at runtime with Mlola Render, as A2UI v0.9 messages: each component's props and allowed values, how surfaces, data binding and actions work, and complete examples. Read once before composing a surface. format "schema" returns the A2UI catalog (JSON Schema) instead.
```

### `get_tokens`

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

Description, as the server wrote it:

```untrusted-server-text
The --ml-* tokens grouped by purpose (planes and ink, color roles, spacing, type, density, shape, depth, motion, layers…). Filter with a group name or part of a token name.
```

### `render_ui`

- The description's first verb is "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Shows an interface in the conversation: a form, a status card, a table of results. Pass A2UI messages composed from the Mlola Render catalog (read get_render_catalog first); they are checked, and drawn with Mlola components where the host shows MCP Apps. When the person presses a button, their next message carries the A2UI action with what they entered. Where the host shows no apps, this answers with the check's report.
```

### `search_components`

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

Description, as the server wrote it:

```untrusted-server-text
Find components, blocks, pages and templates by what they do (for example 'date range', 'chat input', 'pricing'). Returns name, tier (free or Mlola Pro) and a one-line description.
```
