Category Communication
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security78
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability0
- Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability74
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2511 tokens (~279/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 99% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 16 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.
- 14 Oct 26 +3
- The server rewrote its instructions, which are the text every model session reads security
- The server now declares the “prompts” capability functional

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
lessonspace_get_session Get session ~63
One session by uuid, with its space, participants, guests, tags, summary and recording state. GET /organisations/sessions/{session}/.
| Name | Type | Req | Description |
|---|---|---|---|
| session | string | yes | Session uuid (the `uuid` field of a session from lessonspace_list_sessions). |
No output schema declared.
No examples provided.
lessonspace_get_session_recording Get session recording URL ~116
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/.
| Name | Type | Req | Description |
|---|---|---|---|
| session | string | yes | Session uuid (the `uuid` field of a session from lessonspace_list_sessions). |
No output schema declared.
No examples provided.
lessonspace_get_session_transcript Get session transcript URL ~92
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_launch_space Launch a space (create a join link) ~401
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/.
| Name | Type | Req | Description |
|---|---|---|---|
| allow_guests | boolean | – | Let people without an invitation join (Lessonspace default true). |
| id | string | yes | Your id for the space. The same id returns the same space; a new id creates a new space. |
| locale | string | – | Interface language. |
| name | string | – | Display name of the space (defaults to the id). |
| not_after | string | – | The link stops working at this time (default and maximum: 7 days after not_before, or after now). |

| record_av | boolean | – | Record audio and video. |
| record_content | boolean | – | Record the whiteboard and documents (defaults to record_av). |
| server | string | – | Region of the space. If omitted, Lessonspace picks it from the IP location of this server, which is near the AI platform and not near the participant. When the user's region matters, pass the `region… |
| session_tags | object | – | Tags put on the session (for filtering later). |
| space_tags | object | – | Tags put on the space. |
| summarise | boolean | – | Create an AI lesson summary. |
| transcribe | boolean | – | Transcribe the session (needed for lessonspace_get_session_transcript). |
| user | object | – | The participant this link is for. |
| video_layout_mode | string | – | – |

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.
