Anlyon alternative

2 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

Changes things 2Claude Code: ask

    Why it is in this group

    • 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
    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.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
  • unlock_paid_toolsEmail a NativeExpress buyer the key that opens the paid tools on this connector.No findings

    Why it is in this group

    • The name "unlock_paid_tools" says "unlock": a word for a change.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
Only reads 3Show 3 read-only tools
  • get_build_promptThe full text of one prompt from the NativeExpress library, ready to paste, with what to check in the result.No findings

    Why it is in this group

    • The name "get_build_prompt" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
  • get_starter_templateThe free MIT React Native starter repo: its stack, what it already does, what it deliberately leaves out, and the commands to get it running.Reads private dataNo findings

    Why it is in this group

    • The name "get_starter_template" says "get": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "repo": it reads repositories.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
  • list_build_promptsList the prompts in the NativeExpress library for working on a React Native codebase with an agent, with what each one is for.No findings

    Why it is in this group

    • The name "list_build_prompts" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input or outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http nativeexpress https://www.native.express/mcp
claude mcp add --transport http nativeexpress https://www.native.express/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__nativeexpress__get_starter_template",
      "mcp__nativeexpress__list_build_prompts",
      "mcp__nativeexpress__get_build_prompt"
    ],
    "ask": [
      "mcp__nativeexpress__scope_mobile_app",
      "mcp__nativeexpress__unlock_paid_tools"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as nativeexpress. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
