The description mentions "credential".

description: "...ts about a channel. When the call has a credential, each of your comments has `mine: true`..."
```


## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `clear_history`

- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Clears the whole history of the owner at once.
```

### `delete_comment`

- The name "delete_comment" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Deletes a comment of the owner. The 404 is on purpose: the API does not confirm that a comment with that id exists when it is not yours.
```

### `forget_watch`

- The description's first verb is "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

- The name "chat_send" says "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Sends a message to the room of a channel by HTTP. The speaker is the guest (`X-Guest-Token`), the same one that the WebSocket recognizes; without a guest, the account session.
```

## Changes things (19)

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

### `add_favorite`

- The name "add_favorite" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Marks a channel as a favorite. A repeat does not add up: the public counter counts people, not clicks.
```

### `add_item`

- The name "add_item" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Adds a channel to a tab. 40 channels at most per tab. The response tells the folder and the tab where the channel went, so the screen opens in the right place. The response has the whole updated library, so you do not need to reload `GET /api/library`.
```

### `api_index`

- 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.

The index of the whole API, with the languages and the HTML pages of each language.
```

### `channel_health`

- 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
The community health of the channel: the success rate, the failure reasons and the affected environments. It tells 'the channel is off the air' from 'the channel is blocked in your country'. `geo` tells whether it is a regional restriction or a general failure (with the countries), `regions[]` has the success and the failure by country, `latency[]` has the opening speed measured at the hop by country, and `pra_voce` sums it up for the country of the caller. Without community reports (`POST /api/play-report`), the panel is empty.
```

### `chat_history`

- 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.

### `contact`

- The description's first verb is "write": a word for a change.

Write to the people behind the product: a question, or a sponsorship/partnership/advertising proposal. One route for a question and for a sponsorship, partnership or ad proposal (`tipo`, with the placements of `GET /api/partners`). One message every 10 seconds per network: one that arrives sooner waits its turn and then goes out — no error. The message reaches the team by e-mail, with `email` as the reply address. For voice, send multipart/form-data: `dados` is this JSON (up to 32 KiB), and `audio` is one WebM, Ogg or M4A audio file (up to 2 MB). Audio can replace message. The browser records up to two minutes. Audio is attached to the owner's e-mail.
```

### `create_category`

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

Description, as the server wrote it:

```

### `create_group`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `create_guest`

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

Description, as the server wrote it:

```untrusted-server-text
Creates a guest `ipt_…`. It asks for no e-mail and no other data. Keep the token: if you lose the token, you lose the library, unless an account already claimed it (`POST /api/auth/claim`). Then the account keeps what the token saved.
```

### `geo`

- 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
The country and the language suggested for the caller. When the edge detects no country, it suggests BR with `source: "fallback"`; `detected` tells what the edge saw.
```

### `health`

- 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
Liveness and the commit that is published now. The smoke test waits for its own deploy here.
```

### `legacy_stream`

- 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
Public metadata: the official site of the channel, the stream URL to copy into another player, and the legacy HTTP player. The legacy_url button opens http://legacy.gradetv.net/legacy?stream=ID, with no port in the address. The standalone page accepts lang=pt/en/es/fr/de/hu and theme=light/dark. Playlists go through the HTTPS hop, and the media comes directly from the origin. It does not remove an access refusal or a CORS requirement. It is one indexed read: it does not fetch the origin and does not write to the database.
```

### `me`

- 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
The session account (the cookie that the MCP client passes on): the e-mail and the size of the account library. `user.id` is the account id, and the account owns the library when there is a session.
```

### `play_reports`

- 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
The raw reports of a channel, with the address. Operator only (METRICS_TOKEN). Use it to investigate one channel. In the current reports, the `ip` field has an identifier calculated from the network and a secret value. The retention period is in `retention_days`. The public panel does not return this identifier.
```

### `post_comment`

- The name "post_comment" says "post": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Comments on a channel (20 per hour at most per owner). Without `author`, the server makes a nickname that stays the same for the same owner, so the person does not get a different name for each message.
```

### `producer_services`

- 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
Authorized broadcast offer on request: information and contacts for producers. It does not turn on streams; it only gives information and collects interest. To present a project, use contact.form_url in the browser, contact.email by e-mail, or POST /api/contact.
```

### `record_watch`

- 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
Records a watched channel in the owner's history.
```

### `report_play`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Reports whether a channel played (ok=true) or not (ok=false with code). The browser and the system come from the User-Agent, and the country comes from the request data; the body cannot change them. The first report of a result on a day returns 201. It counts once per owner, channel, day and result; a repeat returns 200 with `reason: ja_relatado_hoje`. The reports help to compare results in `GET /api/channels/:id/health`, but they do not confirm the cause of a failure.
```

### `tv_state`

- 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
Checks the activation of the TV network by the six-digit code.
```
