## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 75/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 25% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### How do I install the VAREXIS-INDEX - Source-linked evidence MCP server?

VAREXIS-INDEX - Source-linked evidence is a hosted endpoint at https://varexis.tech/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.

## MCP tools (4)

### `find_evidence_questions` (~228 tokens)

Find published evidence questions

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.

Input parameters:

- `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.

### `preview_evidence_answer` (~128 tokens)

Preview a complete evidence answer

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.

Input parameters:

- `route_id` (string, required)
- `version` (string)

### `find_package_advisories` (~149 tokens)

Find frozen package advisory sources

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.

Input parameters:

- `advisory_id` (string)
- `cursor` (string)
- `ecosystem` (string)
- `package` (string)

### `get_index_access_options` (~117 tokens)

Check INDEX access and cost

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.
