  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100

Install

How do I install the Moltline Creator Studio MCP server?

Moltline Creator Studio is a hosted endpoint at https://mcp.moltlinestudio.com/creator, 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 · 8 exposed · ~1,720 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
analyze_writing ~243

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.

NameTypeReqDescription
textstringyesThe draft to analyze — at least one full sentence; plain text, any length.

Structured output declared, but exposes no named fields.

No examples provided.

get_free_skill ~219

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.

NameTypeReqDescription
slugstringyesProduct slug exactly as returned by list_products, e.g. "brand-voice".

Structured output declared, but exposes no named fields.

No examples provided.

get_full_product ~218

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.

NameTypeReqDescription
slugstringyesProduct slug exactly as returned by list_products, e.g. "brand-voice".

Structured output declared, but exposes no named fields.

No examples provided.

get_full_skill ~220

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.

NameTypeReqDescription
skill_namestringyesExact skill name as listed in that product's "skills" array from list_products.
slugstringyesProduct slug exactly as returned by list_products.

Structured output declared, but exposes no named fields.

No examples provided.

headline_analyzer ~215

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.

NameTypeReqDescription
headlinesarrayyesList of candidate headlines as plain strings; only the first 20 are scored.

Structured output declared, but exposes no named fields.

No examples provided.

list_products ~214

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.

Input schema present but exposes no named parameters.

NameTypeReqDescription
resultarrayyes

No examples provided.

reading_time ~195

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.

NameTypeReqDescription
textstringyesThe content to measure, plain text.
wpmintegerSilent reading speed in words per minute; values below 60 are treated as 60. Default 230.

Structured output declared, but exposes no named fields.

No examples provided.

social_length_check ~196

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.

NameTypeReqDescription
textstringyesThe post or caption text to check, exactly as it would be published.

Structured output declared, but exposes no named fields.

No examples provided.
