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 Security69
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1485 tokens (~297/item across 5 items; 5 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 Management27
- Stability observed for 8 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
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

- 24 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.
- 22 Oct 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

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.

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 →
create_schedule Create timetable ~192
Starts calculating the full timetable from the 8 input files (validate them first). Returns a job_id at once; the calculation takes about 5-8 minutes. Then keep calling get_schedule_result with the job_id in the same reply until it is done.
| Name | Type | Req | Description |
|---|---|---|---|
| files | object | yes | The 8 input files, exactly as described in the interview guide's 'submission' and 'topics'. JSON files are sent as JSON text inside the string; empty CSV files contain only the header line. |
| user_country | string | – | Optional, for anonymous usage statistics: the school's country (e.g. 'Denmark') if the user has mentioned it. Never ask the user just for this. |
| user_language | string | – | Optional, for anonymous usage statistics: the language you talk to the user in (e.g. 'da', 'en'). Fill it in if you know it; never ask the user. |
No output schema declared.
No examples provided.
get_interview_guide Get interview guide ~43
Returns the interview guide: which questions to ask the user, default values, engine limits and the exact format of the 8 input files. Call this first.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_schedule_result Get timetable result ~177
Gets the status or result of a job from create_schedule (or a slow validate_input). While running: progress. When done: a compact timetable as text plus a link (valid 1 hour) to the full JSON result. view='classes' (default) = one table per class, 'teachers' = one per teacher incl. preparation time, 'summary' = key figures and lists of classes/teachers only. Use 'names' to get only some classes/teachers (recommended for big schools). If impossible: the reasons.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | job_id from create_schedule or validate_input |
| names | array | – | Only these classes (e.g. '1.A') or teacher codes (e.g. 'T01') |
| view | string | – | What to show when done (default 'classes') |
No output schema declared.
No examples provided.
send_feedback Send feedback to the developer ~252
Passes the user's feedback about the timetable service on to its developer (what worked, what did not, wishes). Only call it when the user has said they want to give feedback, and send what the user said in their own words (you may shorten it; any language is fine). Never include teacher names, other personal data or the school's data files. Tell the user briefly that it was sent. Nobody replies through this channel - if the user wants an answer, give them the support email timetablingengine.support@gmail.com.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | – | job_id of the timetable the feedback is about, if any |
| message | string | yes | The user's feedback, without names or other personal data |
| sentiment | string | – | Overall tone of the feedback, if clear |
| user_country | string | – | Optional, for anonymous usage statistics: the school's country (e.g. 'Denmark') if the user has mentioned it. Never ask the user just for this. |
| user_language | string | – | Optional, for anonymous usage statistics: the language you talk to the user in (e.g. 'da', 'en'). Fill it in if you know it; never ask the user. |
No output schema declared.
No examples provided.
validate_input Validate input files (free) ~189
Checks the 8 input files in a few seconds without creating a timetable: file structure, engine limits and a capacity analysis (enough teachers/time?). Returns VALID (with warnings) or INVALID (with reasons). Always run this before create_schedule.
| Name | Type | Req | Description |
|---|---|---|---|
| files | object | yes | The 8 input files, exactly as described in the interview guide's 'submission' and 'topics'. JSON files are sent as JSON text inside the string; empty CSV files contain only the header line. |
| user_country | string | – | Optional, for anonymous usage statistics: the school's country (e.g. 'Denmark') if the user has mentioned it. Never ask the user just for this. |
| user_language | string | – | Optional, for anonymous usage statistics: the language you talk to the user in (e.g. 'da', 'en'). Fill it in if you know it; never ask the user. |

How do I install the School Timetable Builder MCP server?
School Timetable Builder is a hosted endpoint at https://timetable-builder.wilbek.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
