Performance

  • Not measured
    Fast (p50)

    Median latency 532 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 532 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

    Parameters documented

    5 of 5 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-30T16:50:08.313942Z, within 180 days.

Capabilities

Tools 5

get_build_prompt

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.

Discovered
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.

Discovered
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.

Discovered
scope_mobile_app

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.

Discovered
unlock_paid_tools

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.
