## 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 2026-10-22.

- **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**: 78/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 792 tokens (~198/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

### 2026-10-22 (score 74)

First indexed and scored.

## MCP tools (3)

### `calculate_personality_scores` (~275 tokens)

Calculate Big Five scores

Use this when the user has answered all 50 items of the IPIP Big-Five Factor Markers test (answers 1-5 in item order) and wants their personality test scores. Returns raw scores (10-50) for Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Intellect/Imagination, an approximate percentile, a low/average/high band with a plain-language description, a share card (SVG) and a share page link. Reverse-keyed items are scored automatically. Does not diagnose anything and is not for hiring decisions. Do not use for other questionnaires (MBTI, DISC, Enneagram) or with invented answers.

Input parameters:

- `answers`: Required. The 50 answers in item order, each 1-5 (1 very inaccurate ... 5 very accurate), e.g. [4,2,4,2,4,2,5,2,4,2, ...]. A string like "4,2,4,2,...", "4242..." or a numbered list "1: 4, 2: 2, ..."…
- `name` (string): Optional first name or nickname for the share card, e.g. Alex. Leave empty for an anonymous card.

Output parameters:

- `disclaimer` (string)
- `domains` (array)
- `downloads` (object)
- `name` (string)
- `norm_note` (string)

### `show_personality_test` (~169 tokens)

Show Big Five personality test

Use this when the user wants to take a personality test, a Big Five (five-factor, OCEAN) test, or a personality test for self-reflection, students, teens or couples. Shows the 50 public-domain IPIP Big-Five Factor Marker items in an interactive widget (one at a time, progress bar, back button); answers stay in the widget until the user submits, then they are scored with calculate_personality_scores. Also returns the item list and a browser link to take the same test. Does not score anything by itself. Do not use for MBTI/16-type, DISC or Enneagram tests, or to screen job candidates.

Input parameters:

- `name` (string): Optional first name or nickname to prefill for the result card, e.g. Alex.

Output parameters:

- `disclaimer` (string)
- `instructions` (string)
- `items` (array)
- `name` (string)
- `scale` (array)
- `test_page` (string)

### `compare_personality_scores` (~220 tokens)

Compare two Big Five profiles

Use this when the user wants to compare two people's Big Five personality test results, e.g. friends, partners or siblings who both took the 50-item test. Takes each person's five raw scores (10-50) and returns per-trait differences (similar when 3 points or fewer apart), each person's percentile, a comparison card (SVG) and a comparison page. Describes differences only; it does not rate compatibility, predict relationships, or judge who is better. Do not use for hiring or team selection.

Input parameters:

- `person_a` (object, required): First person's raw scores, e.g. {"name":"Alex","extraversion":34,"agreeableness":41,"conscientiousness":29,"emotional_stability":30,"intellect_imagination":38}.
- `person_b` (object, required): Second person's raw scores, e.g. {"name":"Sam","extraversion":22,"agreeableness":38,"conscientiousness":44,"emotional_stability":35,"intellect_imagination":31}.

Output parameters:

- `differences` (array)
- `downloads` (object)
- `largest_difference` (string)
- `note` (string)
- `person_a` (object)
- `person_b` (object)
- `similar_count` (number)
