Registers a new wiki as an MCP resource by fetching its sitename and API configuration from any URL on the wiki (e.g. a page URL). The wiki becomes available at mcp://wikis/ and can be targeted by passing its key as the wiki argument to any wiki tool. Fails if the URL is not a MediaWiki wiki or if a wiki with the same key is already registered.

Returns the changes between two versions of a wiki page as a compact text diff. Each side accepts a revision ID, page title (latest revision), or supplied wikitext; text-vs-text is rejected. Only the changes are returned over the wire. For the full text of both sides, fetch with get-page instead. If a title or revision ID does not exist, an error is returned. Set includeDiff=false for a cheap change-detection response that skips diff rendering and returns just the change flag, revision metadata, and size delta. Diff output is truncated at 75000 bytes by default, with a marker reporting how much of it was returned; a narrower revision range or includeDiff=false avoids truncation.

Creates a new wiki page with the provided content and returns the new page's title, page ID, and first revision ID. Fails if a page with the given title already exists; for existing pages, use update-page. The optional contentModel parameter selects a non-default content format (e.g. javascript, css); when omitted, MediaWiki picks the default for the title's namespace. For building up a large page across multiple calls, pair create-page with chained update-page(operation='append') calls, each adding a chunk.

Removes a wiki page from public view and returns the deleted title. This is a soft delete: the page and its revision history remain in the database and can be restored with undelete-page until an administrator purges them. Fails if the page does not exist or the authenticated user lacks the delete permission.

Lists members of a category, returning each member's page ID, namespace ID, and wiki page title. Optionally filter by member type (page, file, subcat) or by namespace ID — filters apply server-side before the cap. Returns up to 500 members per call; paginate with continueFrom (opaque cursor echoed from the previous response). A member's type is omitted when it is an ordinary page (present only for files and subcategories).

Returns metadata for a file (uploader, timestamp, size, MIME type) along with download URLs for the thumbnail, preview, and original. The File: prefix is added automatically if omitted.

Fetches a wiki file server-side and returns the image inline as a content block, for clients that cannot reach the wiki host (sandboxed or network-restricted) and need the image sent to the model for visual analysis. Returns a scaled rendition sized by width. Files MediaWiki can rasterize (images, SVG, PDF, DjVu) come back as an image; other types (audio, video, arbitrary binaries) error — for those, and for metadata or a download URL, use get-file.

Lists pages that reference a target wiki page, returning each referencing page's title, page ID, namespace ID, and whether it is a redirect. The type parameter selects the relationship — wikilinks (pages that link to the target), transclusions (pages that embed it, such as a template), or fileusage (pages that display it, for File pages) — one relationship per call. With expandRedirects, a referencing redirect also yields the pages that link through it (wikilinks and fileusage only), each tagged with the via redirect. Filter by namespace ID or by redirect status. For members of a category, use get-category-members; for full-text content search, use search-page. Returns up to 500 per call; paginate with continueFrom. The redirect flag appears only when the referencing page is a redirect.

Returns a single wiki page (wikitext source, rendered HTML, or metadata only). If the title does not exist, an error is returned. Use metadata=true to retrieve the revision ID (for edit-conflict detection), page size, and section outline. Set content="none" to fetch only metadata. Large content is truncated at 75000 bytes by default, with a marker reporting how much of it was returned and which sections a narrower read can target; a follow-up call with section=N fetches a specific section. For more than one page at a time, use get-pages. For a specific historical revision, use get-revision.

Returns revision metadata (revision ID, timestamp, user, comment, size, minor flag) for a wiki page, in segments of 20 revisions, newest first. Paginate with olderThan or newerThan (mutually exclusive). If the title does not exist, an error is returned. Boolean flags appear only when true.

Returns multiple wiki pages in one call (wikitext source or metadata only). Suited to reading a cluster of related pages, diffing a page family, or syncing pages to local storage. Accepts up to 50 titles; missing pages are reported inline (not as errors). One byte budget covers the whole response, 75000 bytes by default: pages come back whole in the order asked for until it is spent, and the pages past that point are named rather than returned, so a follow-up call for those names fetches the rest. Only a first page larger than the budget on its own is truncated, with a marker reporting how much of it was returned and which sections a narrower read can target. For a single page or HTML output, use get-page. requestedTitle is included only when it differs from the resolved title.

Returns recent change events, newest first, in segments of 50. Defaults to edits and page creations; set types to include log actions, categorizations, or external changes. Each row includes title, timestamp, user, revision IDs, size change, flags (minor/bot/new/anon), tags, and change type. Filter by timestamp window, namespaces, user, change tag, or hide flags (hideBots/hideMinor/hideAnon/hideRedirects/hidePatrolled). Pass showPatrolStatus to include per-row patrol state (requires patrol rights). Paginate with the continue token from the truncation marker. For a single page's revision history, use get-page-history. Boolean flags appear only when true; rows report the size delta, not raw old/new lengths.

Returns a specific historical revision of a wiki page by revision ID (wikitext source, rendered HTML, or metadata only). If the revision ID does not exist, an error is returned. Content is truncated at 75000 bytes by default; a past revision has no narrower read, so for a large one use compare-pages to see what changed. For the latest revision plus metadata, use get-page with metadata=true.

Returns key facts about the targeted wiki from its MediaWiki siteinfo: general settings (sitename, MediaWiki version, content language, page-title case-sensitivity, live read-only state, and maxarticlesize in bytes), the namespace map with localized names and aliases, the list of installed extension names, and the content license. Set includeStatistics to also return page, article, edit, image, user, active-user, and admin counts.

Lists every configured wiki: its key (pass as the wiki argument to other tools), sitename, server URL, whether it is read-only or the default, whether it is currently reachable, and which extension-gated tools work on it. Use to discover the configured wikis, their keys, and which extension tools each supports.

Renames a wiki page, moving it — and by default its talk page — to a new title, and returns the old and new titles plus whether a redirect was left behind. By default leaves a redirect at the old title; set leaveRedirect=false to suppress it (requires the suppressredirect right, otherwise the redirect is left regardless). Fails if the source page does not exist, if the target title already exists (unless it is a redirect and ignoreWarnings is set), or if the authenticated user lacks the move permission. Moving a File page additionally requires the file-move permission.

Removes stored OAuth tokens. With no argument, removes all stored tokens; with wiki, removes only that wiki. Stdio only.

Lists wikis with stored OAuth tokens, their scopes, and expiry. Stdio only. Never returns token values.

Renders wikitext through the live wiki without saving. Returns HTML, parse warnings, categories, wikilinks, templates, external URLs, and display title. Suited to dry-running a planned edit before create-page or update-page, or previewing standalone wikitext (template combinations, sanitizer checks) with no target page. HTML output is truncated at 75000 bytes by default, with a marker reporting how much of it was returned; a smaller wikitext fragment in a follow-up call returns the rest.

Changes the protection of a wiki page and returns its title, its own protections afterwards with their expiries, and whether cascading is on. Each action named in protections is set to its level until expiry. Actions left out keep their current protection, so lifting all protection means naming every action the page takes with "all". Protection the page inherits from a cascade-protected page that transcludes it is neither changed nor listed. Fails if the authenticated user lacks the protect permission, if the wiki does not accept an action or level for this page, or if the expiry is invalid or in the past.

Removes a wiki from the MCP resources. Clears any cached credentials and license metadata for the wiki. Fails if the specified wiki is the configured default wiki.

Searches wiki page titles and page content (full-text) for the provided terms. Returns matching pages with a snippet, size, timestamp, and the namespace the match came from. Covers the namespaces the wiki counts as content unless namespaces names the namespace IDs to search; get-site-info lists a wiki's namespaces and flags which of them hold content. Accepts up to 100 matches per call (default 10); additional matches beyond the cap are flagged in the response — narrow the query to surface more. For title-prefix lookup (e.g. autocomplete), use search-page-by-prefix.

Returns wiki page titles beginning with a given prefix (suited to autocomplete and title lookup). Only titles are returned — no snippets, sizes, or IDs. Accepts up to 500 titles per call (default 10); additional matches beyond the cap are flagged in the response. For full-text content search, use search-page.

Restores a previously deleted wiki page, including its full revision history, and returns the restored title. The page must currently be in a deleted state (from delete-page); fails if no deleted revisions exist for the title or the authenticated user lacks the undelete permission.

Uploads a new revision of an existing file from the local disk, preserving prior revisions in the file history, and returns the file title and URL. The upload appears in the wiki's upload log. Replaces the file content (bytes) only; for editing the wikitext on a file's description page, use update-page. The operator restricts which directories are readable; filepath must be an absolute path inside a configured upload directory, or the call fails before contacting the wiki. Fails if no file exists at the target title; for the initial upload, use upload-file. To upload a new revision from a remote web address instead of a local path, use update-file-from-url.

Fetches a file from a remote web URL and uploads it as a new revision of an existing file, preserving prior revisions in the file history, and returns the file title and URL. The upload appears in the wiki's upload log. Replaces the file content (bytes) only; for editing the wikitext on a file's description page, use update-page. Works whether or not the wiki has upload-by-URL enabled: the server retrieves the file and uploads it directly, falling back to wiki-side fetching only when it cannot reach the URL itself. Fails if no file exists at the target title; for the initial upload, use upload-file-from-url.

Writes to an existing wiki page and returns the new revision ID. Fails if the page does not exist; for new pages, use create-page. operation says what the write does and section says where: omit section to act on the whole page, or set it to confine the write to one section. For changing part of a page, use operation='find-replace', which carries only the text being rewritten, so nothing outside find can be lost and the rest of the page never has to travel to or from the caller; a find that matches nothing, or more than one place, is refused without writing, which also makes it safe to resend a call whose result never arrived. For replacing a target outright, use operation='replace', whose source must carry every byte meant to survive; it is refused when source would shorten a target too large for one read to return whole, since the rest was never seen. With section set it also takes out every subsection nested under that section, is refused when source would drop them, and needs latestId to say which revision the section number was read from. operation='append' and 'prepend' add a delta: a new section at the end of the page is an append whose source begins with the heading, and with section set a prepend inserts one immediately above that section. Pass latestId (reported as latestRevisionId by any get-page read that returns wikitext) for edit-conflict detection: the write is rejected rather than silently clobbering a concurrent change. Each call is a separate revision, and resending an append or prepend whose result never arrived adds the delta a second time.

Uploads a file from the local disk into the wiki's File namespace and returns the resulting file title and URL. The upload appears in the wiki's upload log. The operator restricts which directories are readable; filepath must be an absolute path inside a configured upload directory, or the call fails before contacting the wiki. Fails if a file with the target title already exists (the wiki does not silently overwrite existing files). To upload directly from a remote web address instead of a local path, use upload-file-from-url. To replace an existing file with a new revision, use update-file.

Fetches a file from a remote web URL and uploads it into the wiki's File namespace, returning the resulting file title and URL. The upload appears in the wiki's upload log. Works whether or not the wiki has upload-by-URL enabled: the server retrieves the file and uploads it directly, falling back to wiki-side fetching only when it cannot reach the URL itself. Fails if a file with the target title already exists. To replace an existing file with a new revision, use update-file-from-url.

Returns the identity the current session is authenticated as on the targeted wiki: the username, whether the session is anonymous (no user is logged in), and the user groups it belongs to. Set includeRights to also return the full list of user rights. Use to confirm who edits and uploads will be attributed to before writing — for example, to resolve your own username before building a title under your own user namespace (User:/…). Reports anonymous access rather than failing when the session has no credentials. For which wikis have stored OAuth tokens and their scopes, use oauth-status instead.
