Category Security
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 Security80
- 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
- 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 Usability64
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 695 tokens (~173/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 Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage75
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 25% 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 current MCP spec version (2026-07-28).Pass

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 →
find_evidence_questions Find published evidence questions ~228
Search existing reviewed evidence questions and fixed-pack topics when you do not know a route ID. Use this for governance, tool permissions, audit/export and evidence-boundary questions. For a known software advisory ID or an exact ecosystem/package lookup, use find_package_advisories instead. Supply query as keywords (maximum 160 characters), or leave it blank to browse. offset is the zero-based pagination offset (default 0, maximum 10000; increase by 20). Returns up to 20 matches with route_id, matched wording and the scoped question; pass a route_id to preview_evidence_answer for the complete free answer and sources. Matching ignores case, punctuation and common question words; it does not validate arbitrary new claims. No match is not a negative verdict. Free and read-only.
| Name | Type | Req | Description |
|---|---|---|---|
| offset | integer | – | Zero-based result offset, 0 to 10000; start at 0 and increase by 20 for the next page. |
| query | string | – | Keywords for an existing reviewed question or evidence-pack topic; leave blank to browse the first 20 routes. |

find_package_advisories Find frozen package advisory sources ~149
Look up a known advisory ID or alias, or an exact ecosystem and package name in the frozen OSV collection. Supply advisory_id OR both ecosystem and package; cursor continues the same lookup. Returns at most 20 concise source matches and route IDs for preview_evidence_answer. Source capture dates and withdrawals are explicit. Full previews include separately dated EPSS/KEV matches and explicit fix boundaries; scores are not asset-risk assessments. No results never mean safe. No range solving, current scanning, independent verification or payment. Free and read-only.

| advisory_id | string | – | – |
| cursor | string | – | – |
| ecosystem | string | – | – |
| package | string | – | – |
No output schema declared.
No examples provided.
get_index_access_options Check INDEX access and cost ~117
Call with {} after a free preview to compare paid saved retrieval, unsigned receipts and executable licences. Returns live availability, GBP prices excluding VAT, product requirements and hosted/agent payment contracts, including standalone Tool Admission (GBP49) and Audit Coverage (GBP79). Existing subscriptions exclude these two licences. Use purchase_url for hosted checkout; compatible agents need owner spending authority for the exact quote and must follow agent_payments_contract for payment and recovery. Free evidence needs no payment. Never send keys here; this tool cannot charge or retrieve purchases.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
preview_evidence_answer Preview a complete evidence answer ~128
Preview a published answer or pack using route_id from find_evidence_questions or find_package_advisories. Free; returns cited evidence, review dates, limitations and snapshot_sha256. Public packs include complete comparisons. Executable-product previews show scope, schemas and examples, not the licensed ZIP; the original integration kit also has a distinct preview_payload_sha256. Optional version checks exact advisory-listed versions only, not ranges or safety. For prices and licences, call get_index_access_options. No paid saving or live testing.
| Name | Type | Req | Description |
|---|---|---|---|
| route_id | string | yes | – |
