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 Security63
- 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 403, which proves neither a plaintext path nor enforcement. 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
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 390 tokens (~195/item across 2 items; 2 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 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
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 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.
- 5 Nov 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.
- 3 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

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 →
check_public_pdf Check a public PDF ~185
Downloads one PDF from a public http or https link and reports the structure that screen readers use: whether the file is tagged, whether it has a document title and a language, how many images have no text description and on which pages, and reading-order signals (pages with columns are flagged for a person to check). Also reports the page count and which pages look scanned or contain tables. Use when the user gives a link to a PDF on a public website and asks about its accessibility or screen-reader structure. Does not open files behind a login, does not change the file, and does not say whether the file meets PDF/UA, WCAG or any law.
| Name | Type | Req | Description |
|---|---|---|---|
| detail | boolean | – | When true, adds the page-by-page list. |
| url | string | yes | Link to one PDF on a public website: http or https, at most 2,048 characters. |
No output schema declared.
No examples provided.
quote_fix Estimate the price to make public PDFs accessible ~205
For one to five links to PDFs on public websites, counts pages by type and returns a price estimate from CyberNative AI LLC's published Terms for two options: an accessible web page made from the PDF (USD 6 per page with tables or scanned pages, USD 4 per other page), and, where the file qualifies, the same PDF with tags added (USD 4 per page, minimum USD 100 per order). Lists files and pages that are not converted, such as fillable forms, maps and drawings, with the reason. The estimate is not binding and nothing is ordered by calling this tool; the price is confirmed by email before any work. Use when the user asks what it would cost to have these PDFs made accessible.
| Name | Type | Req | Description |
|---|---|---|---|
| detail | boolean | – | When true, adds the page-by-page count for each file. |
| urls | array | yes | One to five links to PDFs on public websites: http or https, at most 2,048 characters each. |
No output schema declared.
