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 Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (audit_domain). See how to fix → View diagnostics → Fail
- 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 Usability83
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2346 tokens (~130/item across 18 items; 18 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 Management20
- Stability observed for 6 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 18 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 19 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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 →
account_info Bannerproof account ~32
Shows the connected Bannerproof account: plan, how many monitored domains it allows and uses, and the remaining audit credits.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
add_domain Add a domain to monitoring ~121
Adds a domain to weekly monitoring in the connected account (within the plan's domain limit) and runs its first scan. Requires a plan with a free domain slot; otherwise it returns an error that names the plan needed.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | The website's domain, e.g. example.com |
| language | string|null | – | Language for the fix instructions and report links: en, de, fr, es, it, nl, da, sv, fi, no, et, pl or pt. Normally the language of the conversation. Default en. |
No output schema declared.
No examples provided.
audit_domain Audit any website (uses 1 credit) ~208
Full audit of any website (for example a client's or a prospect's site) that is NOT monitored in the account. Spends 1 audit credit, so it is marked destructive and runs only with confirm=true. If the same site was audited in the last 24 hours, the earlier result is returned without spending a credit unless force_new=true. If the site can't be scanned, the credit is returned automatically.
| Name | Type | Req | Description |
|---|---|---|---|
| confirm | boolean | yes | Confirms spending 1 audit credit; without true the audit does not run |
| domain | string | yes | The website's domain, e.g. client-site.com |
| force_new | boolean | – | Run a new paid audit even if this site was audited in the last 24 hours |
| language | string|null | – | Language for the fix instructions and report links: en, de, fr, es, it, nl, da, sv, fi, no, et, pl or pt. Normally the language of the conversation. Default en. |
No output schema declared.
No examples provided.
audit_domains Audit several websites (1 credit each) ~181
Audits up to 10 websites at once (e.g. an agency's client list or prospects). Spends 1 audit credit per new audit and runs only with confirm=true; sites audited in the last 24 hours are reused without spending. If the account doesn't have enough credits for the whole list, nothing starts (no partial batch). A site that can't be scanned (down, blocking bots, too slow) is not charged — its credit is returned automatically. Returns a job_id per site — follow up with get_audits_status for all of them, then get_findings per domain.
| Name | Type | Req | Description |
|---|---|---|---|
| confirm | boolean | yes | Confirms spending 1 audit credit per new audit; without true nothing runs |
| domains | array | yes | The websites' domains, e.g. ["client-a.com", "client-b.de"] — up to 10 |
No output schema declared.
No examples provided.
compare_scans What changed since the last scan ~119
Compares the latest scan of a monitored domain with the previous one (or with the newest scan on or before a given date): new issues, resolved issues, score change, banner and reject option changes. Use it to confirm a fix worked or to see what a site update broke.
| Name | Type | Req | Description |
|---|---|---|---|
| compare_with_date | string|null | – | Optional date (e.g. 2026-10-01): compare with the newest scan on or before that date instead of the previous one |
| domain | string | yes | A domain monitored in the connected account |

No output schema declared.
No examples provided.
get_audits_status Status of several audits ~89
Status of several audits at once (e.g. the job_ids audit_domains returned): which are done with their score and issue count, which are still running, and which failed — with the reason. Failed scans are not charged: their audit credit goes back to the account automatically.
| Name | Type | Req | Description |
|---|---|---|---|
| job_ids | array | yes | The job_ids from audit_domains or audit_domain — up to 10 |
No output schema declared.
