## 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 2026-10-05.

- **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**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1988 tokens (~248/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**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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 (88% 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.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

### `draft_posts` (~239 tokens)

Draft posts for each platform

Use this when the user wants social posts written about a topic, such as "write posts about our new CLI for X, Bluesky and LinkedIn". Pass the topic, with every fact and any link to include, and 1 to 6 platforms from x, bluesky, threads, mastodon, linkedin, instagram, reddit, youtube, pinterest, tiktok; optionally a tone. Returns one draft per platform with its length as that platform counts it, hashtags, whether it passes the platform's rules and the issues if not, plus a checklist of rules and image sizes with sources and dates. Uses only the facts given. It does not publish, read accounts or fetch trends or statistics.

Input parameters:

- `platforms` (array, required): Where the posts will go, up to 6 of x, bluesky, threads, mastodon, linkedin, instagram, reddit, youtube, pinterest, tiktok.
- `tone` (string): Optional voice, such as "friendly and plain" or "dry humour".
- `topic` (string, required): What the posts are about, with any facts, names and link to include. Posts use only what is given here.

Output parameters:

- `ai_disclosure` (object|null): Set when the topic or a draft declares an AI-generated person or voice; names the label that applies on X, Instagram, TikTok and YouTube drafts.
- `as_of` (string)
- `checklist` (array)
- `drafts` (array)
- `message` (string)
- `notice` (string)
- `rules_as_of` (string): Date the platform rules were last checked (2026-10-01).

Returns a script on a fixed clock (hook 0 to 3 seconds, body 4 to 20 seconds, call to action by about 25 seconds) with voiceover, on-screen text and visuals, a timing check, a caption for each platform checked against its rules, each platform's official video length limit with its source, and an ai_disclosure block naming the AI label that applies when the script declares an AI-generated person or voice. Uses only the facts given. It does not publish, make the video, clone voices or write for fake-identity accounts.

Input parameters:

- `platforms` (array, required): Where the video will be posted: tiktok, youtube_shorts, instagram_reels, x_video.
- `tone` (string): Optional voice, such as "friendly and plain" or "dry humour".
- `topic` (string, required): What the video is about, with the facts to use. Say if it will use an AI-generated presenter or voice, so the right label is named.

Returns the adapted text, its language, a short list of what changed and why, and the platform check when one was asked for. It adapts tone, idioms, examples and formats rather than translating word for word, and adds no new claims. Only for the user's own text; it does not publish.

Input parameters:

Each angle has 5 slides (hook, pain, stake, reveal, cta), each a 1080x1920 PNG in png_base64, plus one caption and a hashtag list. Quote the summary field first. It has the counts and the first caption. Save png_base64 as its filename only when the user asks for the files. Stake is the second pain beat. The story reveal listens for the comment what is the app. One call is one plugin-call. The same page is at /slides. It does not publish or store the idea.

Input parameters:

Input parameters:

- `ticket` (string, required): The ticket id that submit_feedback returned.

Output parameters:

- `note` (string)
- `reply` (string|null)
- `status` (string)

LinkedIn recruiter jobs feedback broken links: search openkrill MCP tools by task. Use this to find a tool for recruiter search, LinkedIn keywords, jobs, feedback, a missing tool, bug reports, broken links, CVEs, packages, a domain check, or any other task. Lists tool name, a plain task phrase, and the MCP URL to connect. Feedback itself is submit_feedback on this same server.

Input parameters:

- `keyword` (string): Alias for query: keyword to search.
- `query` (string): Optional task keyword or phrase to search tools (e.g. 'recruiter', 'linkedin', 'feedback', 'broken links', 'jobs'). Omit to list all tools.

### Is the Post Kit MCP server safe to use?

Post Kit scores 67 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Post Kit MCP server expose?

Post Kit exposes 8 tools: draft_posts, draft_video_script, localize_post, launch_video, draft_tiktok_slides, and 3 more. Their descriptions and schemas cost roughly 1,594 tokens of context every time the server is loaded.
