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 Security74
- 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 is enforced; there's no plaintext access path. View diagnostics → Pass
- 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability56
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1278 tokens (~319/item across 4 items; 4 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 Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 87% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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
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.

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 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 →
ask ~461
Ask a Swiss tax question for a business or freelancer. Demo: what comes back is a draft written by AI and validated by no professional; do not use it or pass it on. Fill every intake field you can (jurisdiction, category, entity_type, tax_residence, activity_code, revenue_band, vat_status, cross_border, period, already_filed): matching uses these fields only, never the question text. If all fields match an entry, you get the draft entry with its assumptions, sources and validity window. If any field differs, or no entry exists, you get a sample indicative price band and turnaround instead. To see how a review would be quoted, call `ask` again with `request_quotes: true`; the reply says how your principal can hear when the pilot opens, and `status` shows the sample quotes. Free: nothing is charged and nobody is contacted. Do not use for private matters or for countries other than Switzerland, and send no real personal data.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | yes | Taxonomy path, as search_library returns it (e.g. tax.vat.mwst_registration). |
| facts | object | yes | Intake fields (schema intake.ch-tax.v0). Fill every field you can. Matching uses these only. |
| jurisdiction | string | yes | – |
| language | string | – | Language of the answer. |
| max_budget | object | – | Cap for this question, CHF, VAT excluded. |
| max_wait | string | – | Longest acceptable turnaround, ISO 8601 duration (e.g. P5D). |
| principal | object | – | Public demo: not needed; if sent, it is discarded unread. Send no real data. |
| question | string | – | Public demo: not needed; if sent, it is discarded unread. Send no real data. |
| request_quotes | boolean | – | true after a library miss: asks the professionals for named quotes. Free; nothing is charged until commit. |
| source | string | – | Who is asking: agent (software acting for the principal) or human (a person using the operator's interface). Set by the operator's integration; defaults to the operator's declared default. |
| urgency | string | – | priority asks for a faster turnaround and may raise the quotes. |
No output schema declared.
No examples provided.
commit ~274
Commit to one of the sample quotes returned by `status`: chosen by your principal, or by a rule your principal set explicitly, never by position. Demo: this returns a sample ticket; nothing is ordered, nothing is charged and no professional is contacted. In the pilot this will be the only tool that commits money beyond the plan (the professional's quoted fee, paid to them in full, plus a vidit fee paid by the operator), and only within the budget and policy your principal set.
| Name | Type | Req | Description |
|---|---|---|---|
| accepted_by | string | – | Public demo: not needed; if sent, it is discarded unread. Send no real data. |
| choice | string | yes | The quote_id the principal chose, or "none". |
| chosen_by | string | yes | principal: a person at the principal chose. principal_rule: a rule the principal set or expressly accepted chose. |
| max_budget | object | – | Cap for this question, CHF, VAT excluded. |
| principal_rule | object | – | Required with chosen_by principal_rule: which rule chose, who at the principal set or accepted it, and when. |
| request_id | string | yes | The request_id returned by ask with request_quotes. |
| reuse_opt_in | boolean | – | The principal allows the professional to turn the review, stripped of identifying facts, into a library entry. Revocable. |
No output schema declared.
No examples provided.
search_library ~165
Browse the demo's draft Swiss tax entries before you ask. Free. Each entry was drafted by AI and has been validated by no professional; in the pilot, entries will be validated by a named Treuhänder before they are served. Returns, for each matching entry, the canonical question, its assumptions and the intake fields it matches on. The entry itself comes back only from `ask`, and only when your principal's fields match it. Use it to see which topics exist, or which facts decide an answer, before you collect them.
| Name | Type | Req | Description |
|---|---|---|---|
| category_prefix | string | – | e.g. tax.vat |
| jurisdiction | string | – | – |
| keywords | string | – | Plain words; every word must appear in the entry's question or category. |
| language | string | – | – |
No output schema declared.
No examples provided.
status ~111
Check a request for quotes or a ticket. Free. After `ask` with `request_quotes`, returns three sample quotes from sample professionals ("SAMPLE Professional 1" to "3"), side by side and in no ranked order, as the pilot will show real ones. Choose among quotes only by a rule your principal set explicitly; otherwise present them to your principal and wait; never choose by position. After `commit`, returns the sample ticket.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | A request_id or a ticket_id. |
No output schema declared.
No examples provided.
How do I install the vidit (demo) MCP server?
