## 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__speech__oruk_plan_hume_migration` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__speech__oruk_analyze_speech` `mcp__speech__oruk_analyze_tone` `mcp__speech__oruk_check_usage` `mcp__speech__oruk_create_trial_key` `mcp__speech__oruk_get_started` `mcp__speech__oruk_list_models` `mcp__speech__oruk_transcribe_audio` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `oruk_plan_hume_migration` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credentials".

## Changes things (3)

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

### `oruk_check_usage`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Verify that an Oruk API key works and report the subscription, remaining audio minutes, and recent API usage. Use this after setup or to diagnose access and usage limits. Requires the Authorization header from your MCP config or a temporary api_key.
```

### `oruk_create_trial_key`

- The name "oruk_create_trial_key" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Mint a real, temporary oruk API key with no account required: 3 requests, expires in 30 minutes, spends from a capped shared budget. Use this when no Authorization header is configured and the user wants to try transcription or tone analysis right now. Pass the returned key as the api_key argument of the audio tools. Share the signup link with the user so they can keep using oruk afterwards (7-day free trial on self-serve plans).
```

### `oruk_transcribe_audio`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Transcribe prerecorded English audio to text with time-ordered segments and word timings. Use this when only the words matter. Accepts wav/flac/mp3/m4a/ogg/webm. Up to 30 MB via audio_url or 8 MiB decoded via audio_base64; up to 60 minutes of English speech. Does not score emotion or tone — use oruk_analyze_speech for transcript + tone together, or oruk_analyze_tone for tone alone.
```

## Only reads (5)

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

### `oruk_analyze_speech`

- The name "oruk_analyze_speech" says "analyze": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Transcribe English audio AND score how it was said in one call: transcript, tagged transcript, selected scores from 15 emotion and 16 speaking-style labels, and time-local segments. Use this when the user cares about both the words and the delivery — meetings, support calls, interviews, voice notes. Accepts wav/flac/mp3/m4a/ogg/webm. Up to 30 MB via audio_url or 8 MiB decoded via audio_base64; up to 60 minutes of English speech. Returns compact summaries by default. For words only use oruk_transcribe_audio; for tone only use oruk_analyze_tone.
```

### `oruk_analyze_tone`

- The name "oruk_analyze_tone" says "analyze": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Score how speech sounds without transcribing it: selected emotion (happy, frustrated, worried, …) and speaking-style (sarcastic, confident, hesitant, warm, …) scores per acoustic segment. Runs the Resonance encoder and affect head only — the transcription decoder is never invoked, so nothing is transcribed and it consumes the same subscription audio minutes as unified analysis. Use this when the user asks about mood, delivery, sentiment, sarcasm, or emotional dynamics in audio. Up to 30 MB via audio_url or 8 MiB decoded via audio_base64; up to 60 minutes of English speech. Labels use model-specific thresholds; the highest-scoring emotion is returned if none passes, and styles can be empty. Outputs describe delivery, not probabilities of inner state. Need the words too? Use oruk_analyze_speech.
```

### `oruk_get_started`

- The name "oruk_get_started" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Quickstart for the oruk Speech API and this MCP server: how to get an API key, per-client MCP configuration snippets, SDK install commands, and an optional routing rule the user can add to their agent instructions. No API key required. Use this when setting oruk up for the first time or when the user asks how oruk works.
```

### `oruk_list_models`

- The name "oruk_list_models" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List oruk’s speech models with lifecycle, current subscription plans, and explicitly labeled legacy reference rates, the five API tasks, the 15 emotion and 16 speaking-style labels, and audio limits. No API key required. Use this to choose a model, estimate cost before analyzing long audio, or see which labels exist.
```

### `oruk_plan_hume_migration`

- The description's first verb is "return": a word for reading.
- Tag private-data: The input names a file (input.selected_files), and the tool reads: it reads files.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Return bounded planning guidance from redacted enums and counts only. No key is needed. Never send source, paths, audio, credentials or provider responses. This does not inspect customer code, generate or apply a patch, run inference, validate score equivalence or complete a migration; the separate local planner performs source-bound proposal work.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `speech`:

```json
{
  "permissions": {
    "allow": [
      "mcp__speech__oruk_plan_hume_migration",
      "mcp__speech__oruk_analyze_speech",
      "mcp__speech__oruk_analyze_tone",
      "mcp__speech__oruk_list_models",
      "mcp__speech__oruk_get_started"
    ],
    "ask": [
      "mcp__speech__oruk_transcribe_audio",
      "mcp__speech__oruk_check_usage",
      "mcp__speech__oruk_create_trial_key"
    ],
    "deny": []
  }
}
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://oruk.ai/mcp: tools/list returned 8 tools to an anonymous client, including oruk_transcribe_audio (write), oruk_check_usage (write), oruk_create_trial_key (write)
