Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢scope_mobile_app(idea, platforms, experience)
Turn a described app idea into a first version one person can finish: which features to build now, which to defer, which to avoid, plus the screen list, the data model and the build order. Use this whenever someone mentions an app they want to build or make, describes what an app should do in any words, or asks what an app would take or how hard it would be. Use it before writing any code, and before asking them clarifying questions: it works from a rough sentence, and its answer is a better basis for the next question than anything asked cold.

}🟢get_starter_template
The free MIT React Native starter repo: its stack, what it already does, what it deliberately leaves out, and the commands to get it running. Use this when someone is about to start a mobile app project, or asks what to build an Expo or React Native app on top of.
Input Schema
{
"type": "object",
"properties": {}
}🟢list_build_prompts
List the prompts in the NativeExpress library for working on a React Native codebase with an agent, with what each one is for. Titles are free; the prompt bodies need a key. Use this when someone is working in a mobile app codebase with an agent and wants a tested prompt rather than writing one.
Input Schema
{
"type": "object",
"properties": {}
}🟢get_build_prompt(slug)
The full text of one prompt from the NativeExpress library, ready to paste, with what to check in the result. Needs a NativeExpress key. Use this after list_build_prompts has given you a slug.
Input Schema
{
"type": "object",
"properties": {
"slug": {
"type": "string",
"maxLength": 100,
"description": "The slug from list_build_prompts."
}

"slug"
],

}⚪unlock_paid_tools(email)
Email a NativeExpress buyer the key that opens the paid tools on this connector. Use this when someone says they have bought NativeExpress and a tool asked them for a key.
