Est-ce que com.juzpost/mcp est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.juzpost/mcp » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

• create_post≈ 4504 tokens

  Creates a draft post with everything the composer saves: caption, title, description, hashtags, media, the accounts it goes to, per-account text (account_overrides, channel_overrides), per-account media and covers, and each platform's settings. Media can be public URLs (downloaded and stored server-side) or media keys from upload_media. Use this only once you have the full brief from the user: the post type, the text, and the media if the type needs it. `type` is required and is never guessed: use the type the user stated (text, image, video or blog); if they did not say, ask them before calling this tool. A blog post goes to WordPress: title is required and becomes the page heading. Put the body in description, as HTML; it is sent exactly as written. Plain text also works: blank lines become paragraphs. WordPress keeps p, br, hr, h2 to h6 (with id), ul, ol, li, blockquote, strong, em, a (href, rel, target, title), code, pre, abbr, time, figure, figcaption, the table tags and img (src, alt, width, height). Do not use h1 (the title is already the page heading), script or style (WordPress removes the tag but leaves its text visible). The first image is the featured image; any others are added under the body in order. Images only, no video. Then schedule_post puts the draft on the calendar. To schedule straight away, call schedule_post with the content instead: it creates and schedules in one call. Pass the same idempotency_key on a retry so a network error never makes two drafts. Returns the draft (post) plus warnings[] naming any platform whose caption limit the content exceeds, and created=false when the idempotency_key matched an existing draft. Does NOT schedule or publish anything.

• create_upload_url≈ 592 tokens

  Reserves storage for one file and returns a presigned upload_url (valid 1 day) plus the media_key it will be stored under. Images up to 20 MB, videos up to 200 MB. Use this in Claude Code, a terminal or a script, for a local file or any video: PUT the ORIGINAL file bytes, unmodified, to upload_url with the returned content-type header and exactly `bytes` bytes, then pass media_key to create_post or update_post. Never re-encode, resize or compress the file first. In a chat app that shows cards (Claude.ai, Claude Desktop, Claude mobile) call upload_file instead: the user picks the file and nothing has to be allowed. The PUT goes to the storage host in upload_url (<account>.r2.cloudflarestorage.com). A code sandbox that blocks it needs that host allowed: On Claude.ai a Pro or Max user allows it in Settings → Capabilities; on a Team or Enterprise plan the organization owner adds it in Admin settings → Capabilities → Additional allowed domains. Returns upload_url, media_key, headers and expires_in. Does NOT upload anything by itself, and does NOT accept a URL or base64; use upload_media for those.

• get_context≈ 1338 tokens

  Reports who this connection is, the one workspace it acts on (use switch_workspace to change it), the plan, billing state, entitlements, quotas, limits and a plain-language list of what is blocked right now. Use this to see what the connection can do, and after an error mentions a plan or quota. Returns user, credential, workspace, plan, billing, entitlements, quotas, limits and blocked[]. The plan and quotas.subscription belong to the subscription of the workspace owner (ownedBy says whether that is the user) and are counted across every workspace that owner has; quotas.workspace is this workspace alone. Say which is which when reporting numbers. Does NOT change anything. Needs the Solo plan or higher on the current workspace.

  Returns the full publishing rules for one platform or all of them: caption and title limits and units, media counts, sizes, formats, whether media is required, hashtags, mentions, native scheduling, plus the global file rules. Use this before drafting to answer "will this fit on X / Instagram / TikTok". Returns platforms[] (one object per platform, with effectiveBodyLimit) and global.

• list_accounts≈ 797 tokens

  Lists the social accounts connected to the workspace, with health, how many posts are queued on each, and the effective limits for that account. Use this to pick the accounts for create_post and schedule_post, or to check whether an account needs reconnecting. Returns accounts[] (id, ref, platform, username, health, scheduledCount, limits, blockedByPlan, and seo for WordPress accounts), nextCursor and hasMore. seo is "yoast" when the WordPress site lets this account write Yoast SEO fields (schedule_post wordpress.seo), and "core" when it does not. health.status is the same as the dashboard: an expired access token that renews itself is still active; only needs_reconnect means the user must reconnect. ref is the account as "platform:handle" (e.g. "x:acme_studio"): pass it wherever a tool takes an account, since it is what the person reads when approving; it is null when the account has no handle, and then the id is used. Does NOT connect or disconnect accounts; that happens in the dashboard.

  Lists the choices one account offers for a setting the schedule needs, read live from the platform. Requests: list_board (pinterest, ids go in pinterest.board_id); list_post_type (wordpress, ids go in wordpress.post_type). Use this when the user posts to Pinterest: list the boards, ask which one, and pass its id as board_id. Use list_post_type when the user wants a WordPress post published as something other than a blog post (a short story, a page): pass the matching id as post_type; the name lists the taxonomies that type takes in terms. Returns field (where the ids go) and choices[] with id and name. Refer to a choice by its name when talking to the user. Does NOT change anything.

• schedule_post≈ 3552 tokens

  Schedules a post to one or more accounts at publish_at (ISO 8601 UTC), or publishes immediately with publish_now=true. This publishes to real accounts. One call does it all: without post_id it creates the post from the content and settings given and schedules it; with post_id it schedules that draft, applying any fields sent first. It takes everything the composer can set: caption, title, media, accounts, per-account text (account_overrides, channel_overrides), per-account media and covers, per-account times, and each platform's settings. With post_id, the per-account maps change only the accounts they name, as in update_post: every other account keeps what the draft has. account_ids is the complete list: an account left out is removed. Each platform setting says whether it is required, an account default or optional; a Pinterest account needs pinterest.board_id, from list_options. Every problem on every account is refused in one error, before anything is armed. Use this only after the user has confirmed the content, the accounts and the time. A refused call writes nothing: no draft is created and no draft is changed. Pass the same idempotency_key on a retry without post_id so a network error never makes two posts; with post_id a retry is safe as is. Returns success, post_id and results[] with one row per account (platform, username, status, error). Call get_post afterwards to show exactly what was scheduled. Does NOT publish now unless publish_now is true.

Only the fields passed change; media_keys: null clears the media. The per-account maps (account_overrides, channel_overrides, media_by_account, cover_by_account, each platform's settings) change only the accounts they name: send just the accounts you are changing, and every other account keeps its text, media and settings. An account's entry is its whole text or settings; account_overrides: { id: null } clears that account's text. account_ids is the complete list: an account left out is removed from the post. A scheduled post is checked the way schedule_post checks one, and nothing is written when it is refused. It can no longer be edited from 10 minutes before its first account fires, or once an account has started preparing (an Instagram or Pinterest video prepares earlier). publish_at on a scheduled post moves it; on a draft it is the time the draft keeps. Use this when the user revises a post before it goes out. Returns the updated post and warnings[] for any platform caption limit the new content exceeds. Does NOT edit published or failed posts (returns an error), and does NOT ingest URLs; use upload_media first.

    Text for every account of one platform, keyed by platform id (e.g. "instagram"): "the Instagram caption". Send only the platforms you are changing; null clears the text of that platform's accounts. An account_overrides entry for the same account wins field by field.
  • cover_timestamp_ms · integer · optionnel
    The video frame, in milliseconds, used as the cover when no cover image is set.
  • publish_at_overrides · object · optionnel
    Scheduled posts only: a different time for one account, keyed by account ref or id (ISO 8601 UTC).

• upload_begin≈ 268 tokens

  Called only by the JuzPost upload card, never by the model. Reserves storage for one file and starts a multipart upload. Returns media_key, upload_id, part_size and parts.

• upload_file≈ 318 tokens

  Shows an upload card where the user picks images or videos from their device (images up to 20 MB, videos up to 200 MB); the card stores the original files in the workspace. Use this in a chat app that shows cards (Claude.ai, Claude Desktop, Claude mobile) whenever the user attached a file in the chat or wants to add one from their device: you cannot read their attachment, so let them pick it here. When they finish, the card adds each file name and media_key to your context and asks the user to send a message; pass those media_key values to create_post or update_post. Returns nothing to attach by itself. Does NOT work in Claude Code or a terminal (use create_upload_url there) and does NOT take a link (use upload_media).

• upload_media≈ 626 tokens

  Stores the original image or video in the workspace from a file the chat app hands over, a public URL (up to 100 MB) or inline base64 (up to 3 MB), checking the real file type and the storage quota. Use this when the user gives you a link to attach to a post, or when the chat app hands you their attachment as `file` (ChatGPT does); then pass the returned media_key to create_post or update_post. `file` is filled by the chat app with an https download link, never by you: a path you see such as /mnt/user-data/uploads/… is on the user's side and cannot be read here. For a file the user attached or has on their device, call upload_file in a chat app that shows cards (Claude), or create_upload_url in Claude Code or a terminal. Use `base64` only with the original bytes of a small image you read from disk; never draw, reconstruct, re-encode or compress an image you have only seen. Returns media_key, bytes, content_type and source. Does NOT attach the file to any post by itself and does NOT accept private or local-network URLs.

  Paramètres, retour & exemple (5)

  Paramètres

  • url · string · optionnel
    Public http(s) URL of the original file. Either this, file or base64.
  • file · object · optionnel
    Filled by the chat app (ChatGPT) with the attachment's https download_url; never a local path. Either this, url or base64.
  • base64 · string · optionnel
    The original file bytes as base64, read from disk (a data: URI is fine). Either this, file or url.
  • filename · string · optionnel
  • content_type · string · optionnel
    MIME type, e.g. image/jpeg. Required with base64.
