## 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**: 69/100
  - 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.
  - 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**: 74/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 553 tokens (~138/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**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 93/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 80% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `elucora_capture` (~127 tokens)

Capture verifiable source evidence

Freeze proof of what a web source actually served, before quoting or acting on it. Returns a signed receipt that anyone can verify offline without trusting Elucora. Proves what was served and when, not that the content is true. Sends a network request to the supplied source and consumes receipt quota.

Input parameters:

- `idempotency_key` (string): Stable retry key for this capture.
- `metadata` (object|null): Optional signed scalar metadata.
- `selector` (object|null): Optional text-quote or JSON Pointer selector.
- `url` (string, required): Public HTTP(S) source URL.

### `elucora_attest` (~182 tokens)

Seal a hash you already hold

Prove a piece of content existed at a point in time by sealing its SHA-256 hash. Use when you already hold the bytes — a model output, a tool result, a document. Elucora records that you submitted this hash and when; it does not prove where the content came from or that it is true, because Elucora never saw the source. To prove what a web source served, use elucora_capture instead. Consumes receipt quota.

Input parameters:

- `content_type` (string|null): Optional media type of the content, as described by the caller.
- `hash` (string, required): SHA-256 digest of the content, written as sha256:<64 hex characters>.
- `metadata` (object|null): Optional signed scalar metadata.
- `size_bytes` (integer|null): Optional size of the content, as described by the caller.

### `elucora_get_receipt` (~58 tokens)

Retrieve an Elucora receipt

Fetch an evidence receipt by ID: the source it covers, the exact passage or field that was sealed, the current signature result, and its transparency log and Bitcoin anchor state. Needs no credentials.

Input parameters:

- `id` (string, required)

### `elucora_verify` (~52 tokens)

Verify an Elucora receipt

Check whether an evidence receipt is genuine and unaltered, and what source bytes it covers. Use this before relying on a receipt produced by someone else. Needs no credentials.

Input parameters:

- `id` (string, required)
