nifra_frontendDiagnose a client-side Nifra problem by symptom across every adapter (React, Preact, Solid, Vue, Svelte, and vanilla).No findings
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
Diagnose a client-side Nifra problem by symptom across every adapter (React, Preact, Solid, Vue, Svelte, and vanilla). Returns the likely cause, a concrete fix, and how to verify it. Covers the Nifra server/client seam, hydration mismatches, duplicated framework runtimes, loader-data typing, and adapter-specific reactivity guidance. Call with no args for the index; pass `symptom` (e.g. "hydration mismatch", "value stopped updating") and/or `adapter` to filter.

  What this check looks for
Description, as the server wrote it
Open an interactive, filterable gallery of ALL of nifra's verified code examples (MCP Apps widget) - for browsing and discovering what exists. NOT for fetching one snippet as text: use nifra_example for that. Pass query to pre-filter; the widget also filters client-side.
Annotations the server declares

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
Walk the guided path to build a nifra app end to end - an ORDERED sequence (create → page route → loader → typed API → typed client → auth → background jobs → deploy), not the random-access search of nifra_docs/nifra_example. Call with no args for the step index; pass `step: N` for that step's goal, how to do it (which tool emits the correct artifact), and how to verify it. Use it when scaffolding a new app or learning nifra's flow - each step composes the other nifra_* tools.

- destructiveHint: false
- idempotentHint: true

  What this check looks for
Description, as the server wrote it
Get the exact TypeScript declaration of any exported @nifrajs/* symbol - interface, type, class, function, or const. Each signature is generated from the package's built .d.ts and returns the complete declaration rather than prose. Pass `name` for an exact symbol (e.g. "RateLimitStore", "RouteSchema", "Context", "rateLimit"); pass `query` to search by keyword; omit both for the per-package index of names. A `name` lookup is always the complete declaration; a `query` returns a one-line summary plus the signature, collapsing an oversized body - pass `full: true` to override.

nifra_docsSearch nifra's framework documentation and get back ONLY the matching sections - auth, uploads, ISR, WebSockets, loaders, deployment, anything.Reads private dataReads text others writeNo findings
Why it is in this group
- The description's first verb is "search": a word for reading.
What it can reach
- private-dataThe name "nifra_docs" says "doc": it reads documents.
- untrusted-inputThe description's first sentence says "search" and "web": it reads web pages, which anyone can write.
Description, as the server wrote it
Search nifra's framework documentation and get back ONLY the matching sections - auth, uploads, ISR, WebSockets, loaders, deployment, anything. Call with no query for the cheap section index; pass query (e.g. "isr revalidate") for the top matching sections. Use this instead of reading llms-full.txt (~150 KB) whole. For the EXACT TypeScript of a type/interface/function, call nifra_types instead (don't read .d.ts files).

Why it is in this group
- The description's first verb is "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "get" and "file": it reads files.
Description, as the server wrote it
Get a verified, copy-pasteable Nifra code example for a task - auth route, file upload, ISR page, loader/action, typed client, SSE, deployment, and more. Every snippet is typechecked against the installed Nifra version, so it compiles as-is. Returns code as text for direct use. Call with no query for the grouped index; pass query (e.g. "protected route", "upload", "isr revalidate") for matching snippets.

- 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 outbound.

Reads private data2: Reads files, mail, messages, databases, secrets, calendars or repositories.; nifra_docs
nifra_example
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; nifra_docs
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.

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__nifra-docs__nifra_docs",
      "mcp__nifra-docs__nifra_example"

    "ask": [

    ],
    "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 nifra-docs. Review it before you use it.

Anlyon alternative

4 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.
