## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__nifra-docs__nifra_docs` `mcp__nifra-docs__nifra_example` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__nifra-docs__nifra_docs` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `nifra_types` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "nifra_types" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "nifra_types" says "type": a word for a change.
```

- **warn** Annotations that disagree with the tool in `nifra_gallery` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "nifra_gallery" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "open": a word for a change.
```


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `nifra_frontend`

- 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:

```untrusted-server-text
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.
```

### `nifra_gallery`

- The description's first verb is "open": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `nifra_learn`

- 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:

```untrusted-server-text
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.
```

### `nifra_types`

- The name "nifra_types" says "type": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `nifra_docs`

- The description's first verb is "search": a word for reading.
- Tag private-data: The name "nifra_docs" says "doc": it reads documents.
- Tag untrusted-input: The description's first sentence says "search" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
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).
```

### `nifra_example`

- The description's first verb is "get": a word for reading.
- Tag private-data: The description's first sentence says "get" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `nifra-docs`:

```json
{
  "permissions": {
    "allow": [
      "mcp__nifra-docs__nifra_docs",
      "mcp__nifra-docs__nifra_example"
    ],
    "ask": [
      "mcp__nifra-docs__nifra_types",
      "mcp__nifra-docs__nifra_learn",
      "mcp__nifra-docs__nifra_frontend",
      "mcp__nifra-docs__nifra_gallery"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__nifra-docs__nifra_docs`: private-data, untrusted-input
- `mcp__nifra-docs__nifra_example`: private-data
