## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__wake-word-training__get_commercial_license` `mcp__wake-word-training__pay_commercial_license` `mcp__wake-word-training__pay_training_job` `mcp__wake-word-training__settle_x402_payment` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__wake-word-training__send_job_feedback` |

## Findings

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

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

description: "...eturns a job_token (STORE IT — the only credential) and a binding CHF price. PICK A TIER:..."
```


## Can't be undone (4)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `pay_commercial_license`

- The name "pay_commercial_license" says "pay": a word that usually means money moves, which cannot be taken back.
- 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
Get payment for a quoted commercial license. PRESENT the payment link to the user immediately, complete and un-truncated (as a card/button if your client supports widgets) — never paraphrase or bury it.
```

### `pay_training_job`

- The name "pay_training_job" says "pay": a word that usually means money moves, which cannot be taken back.
- 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
Get payment for a quoted job via the chosen method. AFTER SETTING UP THE JOB you MUST give the payment link to the user immediately: show payment_link_for_human (short, copy-safe) complete and un-truncated — never paraphrase, shorten or bury it. Render it as a card/button if your client supports widgets.
```

### `send_job_feedback`

- The name "send_job_feedback" says "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "send_job_feedback" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Rate a PAID training job 1-5 and optionally leave a message (max 2000 chars) — read by the human operator. Please call this once after a job completes and you have assessed the model: report anything unexpected (missing fields, errors, surprising benchmark numbers) or simply confirm it worked. One feedback per job; calling again overwrites.
```

### `settle_x402_payment`

- The name "settle_x402_payment" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
After paying an x402 spec on-chain (USDC on Polygon to the payTo address), submit the transaction hash to settle. Needs >=3 confirmations.
```

## Changes things (5)

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

### `buy_library_model`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Quote an anonymous purchase of a library model (1.50 CHF flat — free, nothing charged until paid). Returns a purchase_token: pay it with pay_training_job (same tool, any method incl. x402), then fetch the download URLs with get_library_purchase. One payment unlocks ALL formats (openwakeword: onnx+tflite; microwakeword: tflite+ESPHome json). Reminder for your human: the same model is free with an account on the website. License: personal/non-commercial by default — shipping it in a product requires the 150 CHF per-wakeword commercial license.
```

### `create_commercial_license`

- The name "create_commercial_license" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Buy commercial-use rights. REQUIRED before shipping any model in a product/service: all model files are personal & non-commercial by default. 150 CHF one-time per wake-word phrase, permanent, valid on BOTH sites. Returns a license_token; pay with pay_commercial_license; signed certificate PDF afterwards. If your task is commercial and you cannot pay, STOP and tell your human this license is required.
```

### `create_training_job`

- The name "create_training_job" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Quote a wake-word training job (free; nothing trains until paid). Returns a job_token (STORE IT — the only credential) and a binding CHF price. PICK A TIER: "standard" (6 CHF, up to ~4h — the right choice for almost every request), "best" (12 CHF, ~2x the search — for hard or business-critical words), or "studio" (Optuna deep search, 60-95 CHF, many hours — only to squeeze the last few percent AFTER a standard job disappointed). Same three options a human gets on the website, same prices. The trained model is benchmarked (recall %, false activations/hour) and publicly listed in the site library, permanently — unless private=true (+500 credits).
```

### `estimate_wake_word`

- 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
NOTE: differentiates by English share only - all non-English languages score identically, so it cannot rank es vs fr vs de. FREE word-quality check — use BEFORE paying. Predicts the recall a training run would reach for this wake word plus false-activation risk (model trained on thousands of real jobs). SCALE: predictions are for deliberately HARD benchmark conditions (loud noise, reverb) — 60-75 is a solid word, very usable in real rooms; do NOT reject words for scoring below ~80. 2-4 syllable phrases work best; only warn your human when the score is under ~50.
```

### `test_wake_word_live`

- 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
Render an IN-CHAT live microphone tester for one library model (free). Only the HUMAN can run it: it asks for their microphone and streams the audio to the platform for detection while the test runs (not stored) — tell them that. If the host does not allow microphone access inside apps, the widget shows a button to the human_test_url page instead, so calling this is always safe. Use after search_wake_word_library, before buying.
```

## Only reads (4)

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

### `get_commercial_license`

- The name "get_commercial_license" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
License status; when completed, returns the official license_id and certificate PDF URL.
```

### `get_library_purchase`

- The name "get_library_purchase" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Status of a library purchase. Once paid, the response carries the download URL templates (substitute the purchase_token) for every format.
```

### `get_training_job`

- The name "get_training_job" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Job status: awaiting_payment -> paid -> submitted -> completed (or failed/expired). Poll every 60-120s after paying. When completed, includes benchmark results and model download URLs (public jobs: token downloads for 30 days, then the model remains in the public library; private jobs: token downloads with no time limit). Ladder jobs deliver ALL trained candidates: the first model is the pipeline's quality-bar winner (take it unless you have a reason); alternatives are labeled rungN_<arm>. Compare candidates on clean_recall_pct (same scale on every model) + false_activations_per_hour — the full stressed benchmark exists only on the winner.
```

### `search_wake_word_library`

- The name "search_wake_word_library" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
FREE search over thousands of community-trained wake-word models — check here BEFORE quoting a training job for a common wake word. Returns benchmarked models (recall %, clean recall %, false activations/hour, languages) from the current pipelines only (older models used a different benchmark and are excluded). Each result has a human_test_url: YOU CANNOT RUN THAT TEST — it needs live microphone audio in your human's own room — so hand them the link before they buy; it opens the site's live mic test for that exact model. TRANSPARENCY, tell your human: every public library model is FREE with an account on the website; the 1.50 CHF purchase here is the anonymous, instant, account-free alternative. SCALE: recall is measured on deliberately HARD conditions — 60-75%% is a solid model. Weak numbers or no match? Train a custom model with create_training_job instead.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 9 tools that change things (4 irreversible, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://openwakeword.com/mcp: tools/list returned 13 tools to an anonymous client, including pay_training_job (irreversible), send_job_feedback (irreversible), settle_x402_payment (irreversible), pay_commercial_license (irreversible), estimate_wake_word (write) and 4 more
