## 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 2026-09-21.

- **Endpoint Security**: 83/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1780 tokens (~222/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 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.

## MCP tools (8)

### `list_products` (~214 tokens)

List Products

List every product in the Creator Studio line with its included skills. FREE.

Takes no arguments. Returns a list of 20 product objects, each
{"slug": "brand-voice", "name": ..., "tagline": ..., "skills": ["Skill
A", ...], "free_skill": "Gateway Skill Name"}. Use the returned slug
values with get_free_skill, get_full_product, or get_full_skill.

Returns metadata only - no persona text and no skill instructions. Use
when the caller wants to see what this server covers. Not for keyword
search across the whole 138-product catalog, which the catalog server's
search_catalog does, and not for instructions the caller can act on
(get_free_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Output parameters:

- `result` (array)

### `get_free_skill` (~219 tokens)

Get Free Skill

Load a product's free gateway skill with its complete instructions. FREE.

Typical input {"slug": "brand-voice"} returns {"slug": "brand-voice",
"skill": "<skill name>", "instructions": "<full skill text>"}.

Returns exactly one skill - the product's free gateway skill - chosen
automatically from the slug, with no plan required. Use when the caller
wants usable instructions immediately. Not for the product's other skills:
those are named and need get_full_skill with a skill_name, which requires
a paid plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'. Use list_products."}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `slug` (string, required): Product slug exactly as returned by list_products, e.g. "brand-voice".

### `analyze_writing` (~243 tokens)

Analyze Writing

Analyze a draft for readability, passive voice, cliches, and hedging. FREE.

Also measures sentence variety and keyword density, and produces a
prioritized fix list. Typical input {"text": "<your draft>"} returns
{"readability_grade": 9.2, "passive_voice_count": N, "cliches_found":
[...], "hedging_words": [...], "sentence_count": N,
"avg_words_per_sentence": N, "top_repeated_words": [...],
"priority_fixes": ["..."]}.

Use on body prose to find readability and style problems. Not for ranking
titles (headline_analyzer) and not for platform limits
(social_length_check). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "empty text"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `text` (string, required): The draft to analyze — at least one full sentence; plain text, any length.

### `get_full_product` (~218 tokens)

Get Full Product

Load one product in full: its persona plus every paid skill. PREMIUM (license).

Typical input {"slug": "brand-voice"} returns {"slug": ..., "name": ...,
"persona": "<persona text>", "skills": [{"name": ..., "instructions":
...}, ...], "free_skill": {...}}.

Returns persona plus every skill for one product. Use when the caller
wants the whole product. Not for a single skill (get_full_skill) and not
for a free look, which list_products and get_free_skill provide with no
plan. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `slug` (string, required): Product slug exactly as returned by list_products, e.g. "brand-voice".

### `get_full_skill` (~220 tokens)

Get Full Skill

Load one paid skill's complete instructions from a product. PREMIUM (license).

Typical input {"slug": "brand-voice", "skill_name": "Voice Audit"}
returns {"slug": ..., "skill": ..., "instructions": "<full skill text>"}.

Returns one named skill, selected by skill_name. Use when the caller wants
one specific paid skill. Not for the free gateway skill, which
get_free_skill returns with no plan, and not for every skill at once
(get_full_product). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "unknown slug '<value>'"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `skill_name` (string, required): Exact skill name as listed in that product's "skills" array from list_products.
- `slug` (string, required): Product slug exactly as returned by list_products.

### `headline_analyzer` (~215 tokens)

Headline Analyzer

Score and rank up to 20 headlines, best first. FREE.

Scores 0-100 on length, power/emotion words, numbers, structure, and
clarity. Typical input {"headlines": ["7 Mistakes New Writers Make",
"On Writing"]} returns {"ranked": [{"headline": ..., "score": 85,
"notes": ["good length", "contains number"]}, ...]}.

Use when several title options need ranking. Not for email subject lines,
which the outbound server's subject_line_scorer judges against
deliverability signals, and not for body prose (analyze_writing). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `headlines` (array, required): List of candidate headlines as plain strings; only the first 20 are scored.

### `reading_time` (~195 tokens)

Reading Time

Estimate reading and speaking time plus basic content stats. FREE.

Typical input {"text": "<your article>"} returns {"words": 1200,
"reading_minutes": 5.2, "speaking_minutes": 8.6, "paragraphs": 14,
"fit": "newsletter/blog"}.

Use when length and pacing are the question. Not for writing quality or
grade level (analyze_writing). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `text` (string, required): The content to measure, plain text.
- `wpm` (integer): Silent reading speed in words per minute; values below 60 are treated as 60. Default 230.

### `social_length_check` (~196 tokens)

Social Length Check

Check a post against every major platform's length limit at once. FREE.

Covers X, LinkedIn posts and headlines, Instagram captions, Threads,
YouTube titles, and meta descriptions. Typical input {"text": "<post>"}
returns {"chars": N, "platforms": {"x_post": {"limit": 280, "fits":
true, "over_by": 0}, ...}}.

Use before posting, to catch truncation. Not for readability
(analyze_writing) and not for reading duration (reading_time). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

Input parameters:

- `text` (string, required): The post or caption text to check, exactly as it would be published.
