ViewPrinter

ViewPrinter is a hosted MCP server that publishes to social platforms on the user's behalf. You drive it by calling its tools; the user drives you by asking for what they want posted.

The platform names above are in the description so this skill can be found. They are not a list to reason from — platforms_list is the only source of truth for what can publish and what each one accepts. See references/rules/platforms-first.md.

If the tools are not there yet

The nine rules below all assume platforms_list, media_upload and the rest are callable. Installed as a plugin they are — the manifest brings the server. But a skill can be installed on its own, and then none of them exist.

Check before working. If the ViewPrinter tools are not available, the server is not connected, and nothing below applies. Say so and hand it back:

• It is a remote MCP server at https://viewprinter.tech/api/mcp — streamable HTTP, OAuth only. There is no API key to paste anywhere, and any instruction to obtain one is wrong.
• The authorization server advertises Client ID Metadata Documents. A client that only attempts Dynamic Client Registration may fail with "Incompatible auth server: does not support dynamic client registration" — use the client's CIMD flow instead.
• Let the user complete the browser sign-in. Do not ask for credentials in chat.

When to use this

• Posting, scheduling, drafting, rescheduling or cancelling anything
• Connecting a social account, or fixing one that needs reconnecting
• Grouping accounts so a post can name the set instead of listing ids
• Uploading an image or video to attach to a post
• Asking how a post did, or how an account is growing

The shape of the work

1. See what exists — accounts_list, groups_list, media_list
2. Learn the rules — platforms_list, before composing anything
3. Get the media in — media_upload → PUT → media_confirm
4. Queue it — posts_schedule
5. Read what happened — posts_list, posts_performance, accounts_performance

Nothing publishes until posts_schedule returns. Do not tell anyone a post is scheduled before it does.

Rules

Read the one that covers what you are about to do. Do not read all of them.

Rule	Priority	Covers
platforms-first	CRITICAL	Never state platform limits from memory
media-upload	CRITICAL	Uploading is three steps, and step three is the one that counts
destinations	CRITICAL	Workspaces, and why a group is a snapshot
scheduling	CRITICAL	Approval, absolute times, and not posting twice
drafts	HIGH	The word means two unrelated things
refusals	HIGH	A refused post was never saved, and is not a sales opening
amend-and-cancel	HIGH	What can still be changed, and what cannot be recalled
connecting	MEDIUM	Only the user can finish it
reading-results	MEDIUM	Measured when it was measured, and missing is not zero

Honesty constraints that hold everywhere

• Report what the tool returned, not what you expected it to return.
• A refusal is a fact to relay, not a problem to route around. You are running inside somebody else's client.
• Numbers carry the time they were measured. Quote it.
