The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_component Get an appCN component ~108
Everything an agent needs to add and correctly use one appCN component: its docs (anatomy, delight detail, props, usage examples, accessibility notes), the actual source file contents, the npm packages and registry helpers it depends on, and the install command. Prefer installing via the install command rather than pasting `files` by hand — that resolves dependencies for you.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Component slug, e.g. 'button', 'stream-bubble', 'voice-sphere'. |
No output schema declared.
No examples provided.
get_design_guide Get the appCN design guide ~84
appCN's taste layer: the motion duration/easing/spring tokens, the press-scale and haptics conventions, the variant API rules, accessibility requirements, and the explicit 'what NOT to do' list. Read this before writing or modifying any React Native component so the code feels like appCN — never hand-type durations or easings, reach for these tokens.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_install_command Get an appCN install command ~119
The exact command to add an appCN component to a project. Returns three install methods — the appCN CLI (recommended; handles NativeWind + Reanimated setup), shadcn namespaced, and shadcn by URL (zero setup) — for the requested package manager (or all of them).
| Name | Type | Req | Description |
|---|---|---|---|
| manager | string | – | Package manager: npm, pnpm, yarn, or bun. Omit to get commands for all four. |
| slug | string | yes | Component slug, e.g. 'button' or 'voice-sphere'. |
No output schema declared.
No examples provided.
list_components List appCN components ~93
List every appCN component, optionally filtered by category. Returns each component's slug, title, category, one-line description, and its signature 'delight' detail. Start here to see what's available, then call get_component for the full source and docs.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Filter to 'base' (the broad mobile library) or 'ai' (the featured AI-native collection). Omit for all. |
No output schema declared.
No examples provided.
search_components Search appCN components ~78
Find appCN components by intent or keyword — e.g. 'chat input', 'voice indicator', 'streaming message', 'reasoning'. Returns ranked matches with their delight detail. Use get_component on the best match for the full source and docs.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | What you're looking for, in plain words (intent or keywords). |
No output schema declared.
No examples provided.
