On 2026-10-27 the server answered initialize and tools/list without a sign-in. First answer in 106 ms.

• Its tools do every use case we checked: Publish one post to many social networks; Post to connected accounts from an AI assistant.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• get_context

  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…

• list_workspaces

  Lists every workspace the user belongs to, marks the one this connection acts on, and says what each allows through the connector: none (Free or no plan) or full (Solo, Growth, Pro). Use this when the user names another workspace or a…

• switch_workspace

  A connection acts on one workspace at a time. This moves it onto another workspace the user belongs to (id or slug from list_workspaces) for every later call, until switched again, and returns the new context. Use this when the user names…

• list_accounts

  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…

• list_options

  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…

• get_platform_limits

  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…

• list_groups

  Lists channel groups (named sets of accounts) with their member account ids. Use this when the user names a group ("post to my brand accounts") to resolve it to the account ids schedule_post takes. Returns groups[] (id, name, accountIds…

• list_posts

  Lists posts in the workspace: drafts, scheduled, published and failed. Use this to find drafts to schedule, to review the queue, or to find a post id for get_post, update_post or delete_post. Returns posts[] (id, status, type, title…

• get_post

  Fetches one post with its per-account rows: status, publish time, published time and any error per account. Use this after schedule_post to confirm what happened, or when the user asks why a post failed. Returns the post (content, media…

• create_post

  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…

• update_post

  Edits a draft or a scheduled post, the same edit the composer makes: caption, title, description, hashtags, type, media keys, cover, accounts, per-account text, media and covers, platform settings, and the time. Only the fields passed…

• delete_post

  Permanently deletes a draft post and its target rows. Use this only when the user explicitly asks to discard a draft. Returns deleted=true, the post id and what the deleted draft was (title, caption, type, media count). Does NOT delete…

• schedule_post

  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…

• upload_file

• upload_media

  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…

• create_upload_url

  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…

• upload_begin

  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_part

  Called only by the JuzPost upload card, never by the model. Stores one part of a file started with upload_begin: the original bytes as base64, exactly part_size bytes except the last part. Returns part_number and bytes.
