## 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 2026-08-18.

- **Endpoint Security**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 83/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 491 tokens (~122/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-18 (score 68, +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.

### 2026-08-17 (score 67, 0)

- [functional improvement] Stability: unverified → 0.03
- [functional] Server version: 1.1.0 → 1.2.0

## MCP tools (4)

### `jidec_cite` (~163 tokens)

Cite and independently verify a JIDEC record

Resolve and INDEPENDENTLY verify any JIDEC citation. Accepts 'jidec:path:<sha>', 'jidec:entry:<n>', a bare 64-hex id, or a ledger URL. Fetches the record's exact bytes, recomputes SHA-256 locally, and confirms it equals the cited id. Returns integrity, Bitcoin anchoring status, the parsed record (verification path, claim, or v0 spec entry), and an explicit statement of what the proof does and does not cover. No trust in HORIZON SHIELD is required to accept the result.

Input parameters:

- `citation` (string, required): jidec:path:<sha> | jidec:entry:<n> | 64-hex | ledger URL

### `jidec_replay` (~99 tokens)

Re-observe an anchored path and report drift

Re-observe an anchored JIDEC verification path against the live system right now and report drift. Returns MATCH (the live system still matches what was anchored) or DRIFT (it changed), node by node. Nodes that cannot be re-observed server-side are reported as deferred, never counted as drift.

Input parameters:

- `citation` (string, required): jidec:path:<sha> | jidec:entry:<n> | ledger URL

### `jidec_list_paths` (~34 tokens)

List anchored verification paths

List the anchored JIDEC verification paths (most recent first), with purpose, verdict and Bitcoin anchoring status.

### `jidec_how_to_verify` (~112 tokens)

Get the executable verification recipe

Return the step-by-step recipe for verifying a JIDEC record WITHOUT trusting HORIZON SHIELD: which bytes to fetch, which hashes to recompute, which OpenTimestamps proof to check, which algorithm commit to check out, and what must match. Use this when you want to confirm the result yourself rather than repeat an assertion.

Input parameters:

- `citation` (string, required): jidec:path:<sha> | jidec:entry:<n> | 64-hex | ledger URL
