Wiki Js

An MCP server for Wiki.js — lets AI agents create, read, update, search, list, and move wiki pages via the Wiki.js GraphQL API.

Tools

Tool	Description
wiki_get_page	Read a page's content and metadata by path
wiki_create_page	Create a new page with markdown content
wiki_update_page	Update content, metadata, or patch a named section
wiki_search_pages	Full-text search — returns title, path, description, tags
wiki_list_pages	List pages with an optional path-prefix filter
wiki_move_page	Rename or restructure a page path

All tools return {"success": bool, "error": str | null, ...} and never raise — the calling agent decides how to handle failures.

Section patching

wiki_update_page supports surgical updates to named sections without touching the rest of the page. Fence any block in your wiki content with HTML comments:

<!-- OSIA:AUTO:watchlist -->
Content managed by the AI agent goes here.
<!-- /OSIA:AUTO:watchlist -->

Then call:

wiki_update_page(
    path="desks/geopolitical-and-security",
    section="watchlist",
    section_content="- Benjamin Netanyahu (🔴 Critical)\n- ...",
)

The markers and surrounding content are left untouched.
