## Findings

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

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

description: "...for one participant. The link is a live credential for a real person: share it only with t..."
```


## Deletes or cancels (2)

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

### `lessonspace_launch_space`

- The description's first verb is "write": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
WRITE: create a space, or reuse the one with the same `id`, and get a join link (client_url) for one participant. The link is a live credential for a real person: share it only with that person and never post it elsewhere. Calling again with the same id reuses the space but issues a new link; it is not safe to repeat blindly. Lessonspace's own `secret` is never returned. POST /spaces/launch/.
```

### `lessonspace_update_session`

- The name "lessonspace_update_session" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
WRITE: rename a session and optionally set who may watch its recording (a list of participant, admin, teacher, student; an empty list falls back to the organisation policy). The name is always sent (Lessonspace requires it). PATCH /organisations/sessions/{session}/.
```

## Only reads (7)

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

### `lessonspace_get_session`

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

Description, as the server wrote it:

```untrusted-server-text
One session by uuid, with its space, participants, guests, tags, summary and recording state. GET /organisations/sessions/{session}/.
```

### `lessonspace_get_session_recording`

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

Description, as the server wrote it:

```untrusted-server-text
The playback URL of a session's recording. status 'ready' = the URL works now; 'preparing' = Lessonspace is still creating it (ask again in a minute); 'no_recording' = recording was disabled, so none exists. The URL is an access link: give it only to someone entitled to watch the recording. GET /organisations/sessions/{session}/playback/.
```

### `lessonspace_get_session_transcript`

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

Description, as the server wrote it:

```untrusted-server-text
A signed download URL for a session's transcript. Only works if transcription was switched on for the session (launch with transcribe=true). The URL is an access link: give it only to someone entitled to read the transcript. GET /organisations/sessions/{session}/transcript/.
```

### `lessonspace_list_sessions`

- The name "lessonspace_list_sessions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organisation's sessions (a session is one meeting held in a space): name, uuid, start/end time, space, participants (name, email, role), guests, billable seconds, tags, summary and recording state. Filter by time, duration, participant, space, launch id or tags. Newest first as Lessonspace orders them. Each session's playback_url is an access link to its recording, and participant emails are personal data: treat both as sensitive and share them only with someone entitled to see them. GET /organisations/sessions/.
```

### `lessonspace_list_space_sessions`

- The name "lessonspace_list_space_sessions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Sessions held in one space, with the join/leave log (who joined, left or went idle, and when) and the users connected now. Same filters as lessonspace_list_sessions. GET /spaces/{space}/sessions/.
```

### `lessonspace_list_spaces`

- The name "lessonspace_list_spaces" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organisation's spaces (persistent rooms): id, name, slug, alias, url, tags, lock state, region and recording/transcription settings. The url of a space is a way in; treat it as sensitive. GET /organisations/spaces/.
```

### `lessonspace_list_users`

- The name "lessonspace_list_users" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the organisation's users: Lessonspace user id, name, email, role (teacher, student, admin), active state and external id. Names and emails are personal data. GET /organisations/users/.
```
