Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1332 tokens (~222/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the PrePublish - YouTube script QA MCP server?
PrePublish - YouTube script QA is a hosted endpoint at https://mcp.prepublish.ai/, 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.

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 →
audit_hook Score the opening of a YouTube script ~235
Score just the opening lines of a YouTube script: how much attention each sentence pulls, whether it opens a curiosity gap, how far away the payoff sits, plus the top issues and rewritten alternatives. Choose this when the user shares only a hook or opening paragraph, or wants a fast second opinion before auditing a whole draft. Cheaper and narrower than audit_script. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| string | – | Only needed once the free anonymous hook check for the day is used. Ask the user; never invent it. When the caller is authenticated with a Prepublish API key the result comes back in the conversation… | |
| hook_text | string | yes | The opening lines exactly as written, ideally the first 15 to 30 seconds of speech. |
| niche | string | – | Channel niche, only if the user said it. Sharpens the comparison. |

No examples provided.
audit_script Audit a YouTube script before recording ~354
Run Prepublish's full audit on a YouTube script the user has already written. Returns hook, structure and pacing scores, a script-level attention-risk map naming the passages most likely to lose viewers, and a copy-paste rewrite for each flagged passage. Choose this when the user has a finished or near-finished draft and wants to know what is weak before they record. Do not use it to generate a script, to review a published video, or to check grammar. A free result is released by email, so ask the user for an address rather than guessing one. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| audience | string | – | Target audience, only if the user said it. |
| category | string | – | Video category, only if the user said it. |
| string | – | Where the free result is sent. Required for every anonymous audit: the backend rejects the request without it. Ask the user; never invent it. When the caller is authenticated with a Prepublish API ke… | |
| script_text | string | yes | The script text as the user wrote it. Paste it verbatim; do not rewrite, summarise or clean it first. |
| video_duration_seconds | integer | – | Intended runtime in seconds, only if the user stated one. Used for pacing; never assumed. |
| video_title | string | yes | The title the user plans to publish under. The audit checks whether the script delivers this promise. |
No output schema declared.
No examples provided.
check_authenticity Check a script for reused or inauthentic content risk ~150
Check a script against YouTube's inauthentic-content expectations: whether it reads as mass-produced, templated or repetitive, which signals fire, and what to change. Returns a score, a risk level, the firing signals with quotes, and remediation steps. Choose this when the user worries about reused content, AI-sounding scripts, or a channel that repeats a formula. This reports text-level signals only; it is not a monetisation decision and does not speak for YouTube.
| Name | Type | Req | Description |
|---|---|---|---|
| script_text | string | yes | The script text as the user wrote it. Paste it verbatim; do not rewrite, summarise or clean it first. |
| video_title | string | yes | The planned title. |
No output schema declared.
No examples provided.
get_audit Collect a Prepublish audit by id ~127
Fetch the current state of an audit that was started earlier, using the analysis_id that audit_script returned. Use this when a previous audit was still running, or when the user refers back to an audit from earlier in the conversation. It performs no new analysis and costs nothing. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| analysis_id | string | yes | The analysis_id returned by audit_script. |
No output schema declared.
No examples provided.
policy_preflight Pre-flight a script against YouTube advertiser and monetisation policy ~174
Check a script before recording for the YouTube policy categories it may touch: which category families are implicated, the consequence family for each, a verdict and flag counts. Each category cites YouTube's own published policy page. Choose this when the user is writing about sensitive subject matter and asks whether it is safe to monetise. The quoted passages and their suggested rewrites are part of the paid audit, so the free result may return counts with locked quotes. It reports risk against published policy text; it is not a monetisation guarantee and does not speak for YouTube.
| Name | Type | Req | Description |
|---|---|---|---|
| script | string | yes | The script text as written, at least 200 characters. Below that there is not enough context for a policy read. |
| title | string | – | The planned title, if the user has one. Titles are checked too. |
No output schema declared.
No examples provided.
script_runtime Convert script length to spoken runtime ~175
Convert a word count, or a pasted script, into a spoken runtime range, and convert a target runtime back into a word budget. Rates come from Prepublish's own measurement of 349 videos: 25th percentile 160 words per minute, median 181, 75th percentile 201. Choose this for "how long will this script run" or "how many words for a ten-minute video". It is arithmetic on speaking rate only: it excludes pauses, B-roll and demonstrations, so a finished edit usually runs longer.
| Name | Type | Req | Description |
|---|---|---|---|
| script_text | string | – | A script to count. Provide this or word_count or target_minutes. |
| target_minutes | number | – | A target runtime in minutes, to convert into a word budget. |
| word_count | integer | – | A word count, if the user already knows it. |
