Human and agent roles

Configured boundary

Configured workspace

Postdom Chat only, with the signed-in owner's or admin's authority. Not on the agent MCP menu. A day of the week is not a rule the product has, and this tool never pretends one is: the honest alternatives are a daily limit, quiet hours, or asking before every post. On one account it answers the rule it was asked about and keeps the rest: a field this call does not name and the account was not already overriding goes on following the workspace. Propose, then confirm: the API refuses any call the assistant's own previous answer did not propose and the person's current message does not agree to. The proposal is read from the end of that answer only: the last sentence ending in a question mark, plus the one sentence before it. Those sentences carry the new value and where it lands - the asking level as its own sentence, posts per day as a digit, quiet hours as HH:MM to HH:MM or the words no quiet hours, a pause as pause or resume, brand notes as the section text in double quotes - with @handle for one account or the word everywhere for the workspace. One change per question: a question that offers two changes, joins alternatives with or, or names two accounts (or an account and the workspace) is refused, because a yes does not say which. Anything else is refused with rules_change_not_asked before the call. The proposal is what is read: a daily number as digits or words, a quiet hour as 23:00, 11pm or midnight, and turning the quiet hours off named as such - a bare off is not a rule. An account-scoped write has to be proposed for that account by handle or platform, and a workspace-scoped one is refused whenever the proposal names any account and carries no workspace word. A platform two accounts share names neither of them, so a proposal for one of two Instagram accounts has to carry its @handle.

This reference describes a connection made with @postdom/mcp@0.4.0 and a workspace-scoped agent key created in Accounts.
