How is this different from creating a page?

Creating makes a new page; updating edits one that already exists, by its id. Most documentation work is updates, since a spec or runbook changes far more often than a new one is written. Editing in place keeps the page's id, history, and links rather than spawning a duplicate.

Do I have to resend the whole page?

Depends on the tool, but the intent is to change an existing page, not replace it wholesale. An agent supplies the edit, a corrected line, a new section, against the page's id, which keeps the rest of the content and the page's identity intact.

MCP servers that can update a page

4 verified servers expose a tool that can update a page or document

A doc is rarely done when it is created. A spec gets revised, a runbook gets a new step, a wiki page gets corrected. Updating a page changes the content of one that already exists, so an agent can keep documentation current in place rather than creating a second version.

These verified servers let an agent update a page or document.

What to know

The update is what keeps a knowledge base from rotting. An agent fixing an outdated instruction, appending a result, or correcting a fact is editing the existing page, which avoids the mess of duplicate docs that each say something slightly different. The servers here change a page by its id: Notion updates a page's properties and content, Outline a document's content or metadata, MediaWiki an existing wiki page, ClickUp a doc page's content. Editing in place keeps the page's id, history, and links intact.

Updating in place is also why remembering the page matters. An agent that cannot find the doc it wrote before will create a new one instead of revising it, and the knowledge base fills with near-duplicates. Holding the page's id lets the agent improve the canonical version rather than fork it.
