MediaWiki MCP Server

NPM Version MIT licensed

An MCP (Model Context Protocol) server that enables Large Language Model (LLM) clients to interact with any MediaWiki wiki.

Features

Tools

Every tool that operates on a wiki accepts an optional wiki argument naming the wiki to act on (the wiki-management and OAuth tools do not) — pass a wiki key (e.g. en.wikipedia.org) or the full mcp://wikis/{wikiKey} URI. Omit it to use the configured default wiki (see Configuration). Each tool response reports the wiki the call ran against.

Page reads

Name	Description
`compare-pages`	Diff two versions of a wiki page by revision, title, or supplied wikitext.
`get-category-members`	List members of a category (up to 500 per call, paginated via `continueFrom`).
`get-file`	Fetch a file page.
`get-file-data`	Fetch a file's image bytes inline (base64) for visual analysis — for clients that can't reach the wiki host. Returns a scaled rendition (set `width`); non-renderable types (audio, video, binaries) error. For metadata or a download URL, use `get-file`.
`get-links-here`	List pages that reference a wiki page — pages that link to it, embed it as a template, or display it as a file (select via `type`), including pages that reach it through a redirect. Up to 500 per call, paginated via `continueFrom`.
`get-page`	Fetch a wiki page.
`get-page-history`	List recent revisions of a wiki page.
`get-pages`	Fetch multiple wiki pages in one call (up to 50).
`get-recent-changes`	List recent change events across the wiki, filterable by timestamp, namespace, user, tag, type, and hide flags (up to 50 per call, paginated via `continue`).
`get-revision`	Fetch a specific revision of a page.
`get-site-info`	Get a wiki's key settings: MediaWiki version, content language, title-case rules, namespaces, installed extensions, license, and (optionally) statistics.
`list-wikis`	List every configured wiki — its key, sitename, server, whether it is read-only or the default, whether it is reachable, which extension-gated tools work on it, and, for an OAuth-configured wiki, its authorization server. Disabled when fewer than two wikis are configured.
`parse-wikitext`	Render wikitext to HTML without saving. Returns parse warnings, wikilinks, templates, and external URLs.
`search-page`	Search wiki page titles and contents.
`search-page-by-prefix`	Search page titles by prefix.
`whoami`	Report the identity the current session is authenticated as on the targeted wiki — username, whether it is anonymous, and group memberships (optionally user rights).

Resources

mcp://wikis/{wikiKey} — per-wiki resource exposing sitename, server (the wiki's public address), articlepath, scriptpath, and a private flag.

Credentials (token, username, password) are never exposed in resource content.
After add-wiki or remove-wiki, the server sends notifications/resources/list_changed so clients refresh.

{
  "contents": [
    {
      "uri": "mcp://wikis/en.wikipedia.org",
      "mimeType": "application/json",
      "text": "{ \"sitename\":\"Wikipedia\",\"server\":\"https://en.wikipedia.org\",\"articlepath\":\"/wiki\",\"scriptpath\":\"/w\",\"private\":false }"
    }
  ]
}

Environment variables

Name	Description	Default
`CONFIG`	Path to your configuration file	`config.json`
`MCP_ALLOW_STATIC_FALLBACK`	Set to `true` to allow HTTP startup when `config.json` has static credentials. See docs/deployment.md — security checklist.	`unset`
`MCP_CONTENT_MAX_BYTES`	Byte cap for content bodies (wikitext, rendered HTML, diffs). Tune to the target LLM client's tool-response budget.	`50000`
`MCP_FILE_DATA_MAX_BYTES`	Hard cap on the base64-encoded size of a `get-file-data` response. A transport/safety backstop; tune the actual size per call with the tool's `width`. Over-cap calls error rather than truncate.	`1000000`
`MCP_UPLOAD_MAX_BYTES`	Memory cap on the server-side fetch used by `upload-file-from-url` / `update-file-from-url`. Files larger than this are handed to the wiki's own copy-upload instead of being buffered by the server. Guards this server's memory, not the wiki's `$wgMaxUploadSize`.	`104857600`
`MCP_LOG_LEVEL`	Minimum severity for logger output. One of `debug`, `info`, `notice`, `warning`, `error`, `critical`, `alert`, `emergency`, or `silent`.	`debug`
`MCP_OAUTH_CREDENTIALS_FILE`	Override the default credentials store path. Default: `~/.config/mediawiki-mcp/credentials.json` (Linux/macOS) or `%APPDATA%\mediawiki-mcp\credentials.json` (Windows).	`unset`
`MCP_OAUTH_NO_BROWSER`	Set to `1` to skip launching a browser during the OAuth flow; the auth URL is logged to stderr instead. Useful in headless environments.	`unset`
`MCP_PUBLIC_URL`	Override the request-derived public URL used in OAuth protected-resource discovery. Useful for reverse-proxy setups that rewrite the `Host` header.	`unset`
`MCP_MAX_REQUEST_BODY`	Maximum HTTP request body size (StreamableHTTP transport). Accepts size strings like `512kb` or `1mb`. Oversize requests get a JSON-RPC 413.	`1mb`
`MCP_METRICS`	Set to `true` to expose Prometheus metrics at `GET /metrics` on the HTTP transport.	`unset`
`MCP_SESSION_IDLE_TIMEOUT`	Seconds an HTTP session may sit idle before it is closed and removed (StreamableHTTP transport). Any request resets the timer. `0` disables expiry.	`1800`
`MCP_SHUTDOWN_GRACE_MS`	Maximum ms to wait for in-flight `/mcp` calls to drain on `SIGTERM` / `SIGINT`. See docs/operations.md — Graceful shutdown.	`10000`
`MCP_TRANSPORT`	Type of MCP server transport (`stdio` or `http`)	`stdio`
`MCP_TRUSTED_HOSTS`	Comma-separated hosts exempt from the outbound SSRF guard's public-IP check — for deliberately pointing the server at an internal destination such as a Docker-network alias (`mediawiki.svc`). Distinct from the inbound `MCP_ALLOWED_HOSTS`; see Security.	`unset`
`PORT`	Port used for StreamableHTTP transport	`3000`

Configuration

NOTE

Config is only required when interacting with a private wiki or using authenticated tools.

Create a config.json file to configure wiki connections. Use the config.example.json as a starting point.

{
  "defaultWiki": "en.wikipedia.org",
  "wikis": {
    "en.wikipedia.org": {
      "sitename": "Wikipedia",
      "server": "https://en.wikipedia.org",
      "articlepath": "/wiki",
      "scriptpath": "/w"
    }
  }
}

Internal vs public address. The server you configure is the address the MCP server uses to reach the wiki's API — it may be an internal hostname (e.g. http://mediawiki in Docker). URLs handed back to the AI (page links, the server field in list-wikis and mcp://wikis resources) are built from the wiki's own public address, so internal hostnames don't leak into links. If a wiki can't be reached, links fall back to the configured server.

For the full field reference, env-var substitution, secret sources, change tags, upload directories, and authentication options, see docs/configuration.md.

Authentication

Tools marked 🔐 require authentication. Write tools (including extension-pack writes) are hidden from tools/list when the configured default wiki has readOnly: true — see Deployment.

Browser-based OAuth (recommended). Sign in through a browser tab the first time a tool needs auth. Set oauth2ClientId and oauth2CallbackPort per wiki — see docs/configuration.md — OAuth (browser-based).
Per-request bearer token (HTTP). Each request carries Authorization: Bearer <token>; the server forwards it to MediaWiki. See docs/deployment.md — per-request bearer token.
Hosted OAuth proxy (HTTP). The server fronts one MediaWiki consumer as an OAuth 2.1 Authorization Server, so an OAuth-aware client signs each user in — no manual tokens. Point it at https://<wiki>/mcp; anonymous read still works. See docs/deployment.md — hosted OAuth sign-in.
Manual OAuth2 access token. Paste a long-lived token into config.json. See docs/configuration.md — manual OAuth2 access token.
Bot password. Fallback when Extension:OAuth isn't installed. See docs/configuration.md — bot password.

The Cargo tools (cargo-query, cargo-list-tables, cargo-describe-table) call API actions gated by the runcargoqueries user right. Most wikis grant this to all users by default; wikis that restrict it require the Create, query and delete data through the Cargo extension grant on the bot password or OAuth consumer. The Cargo extension is also detected on wiki.gg-hosted wikis (Helldivers, Terraria, Ark, etc.), where it ships under the rebranded name LIBRARIAN.

Installation

Follow the guide, use following configuration:

{
  "mcpServers": {
    "mediawiki-mcp-server": {
      "command": "npx",
      "args": [
        "@professional-wiki/mediawiki-mcp-server@latest"
      ],
      "env": {
        "CONFIG": "path/to/config.json"
      }
    }
  }
}

code --add-mcp '{"name":"mediawiki-mcp-server","command":"npx","args":["@professional-wiki/mediawiki-mcp-server@latest"]}'

Install in Cursor

Go to Cursor Settings -> MCP -> Add new MCP Server. Name to your liking, use command type with the command npx @professional-wiki/mediawiki-mcp-server. You can also verify config or add command like arguments via clicking Edit.

{
  "mcpServers": {
    "mediawiki-mcp-server": {
      "command": "npx",
      "args": [
        "@professional-wiki/mediawiki-mcp-server@latest"
      ],
      "env": {
        "CONFIG": "path/to/config.json"
      }
    }
  }
}

Follow the guide, use following configuration:

{
  "mcpServers": {
    "mediawiki-mcp-server": {
      "command": "npx",
      "args": [
        "@professional-wiki/mediawiki-mcp-server@latest"
      ],
      "env": {
        "CONFIG": "path/to/config.json"
      }
    }
  }
}

Follow the Claude Code MCP docs.

Run the below command, optionally with -e flags to specify environment variables.

claude mcp add mediawiki-mcp-server npx @professional-wiki/mediawiki-mcp-server@latest

You should end up with something like the below in your .claude.json config:

"mcpServers": {
  "mediawiki-mcp-server": {
    "type": "stdio",
    "command": "npx",
    "args": [
      "@professional-wiki/mediawiki-mcp-server@latest"
    ],
    "env": {
      "CONFIG": "path/to/config.json"
    }
  }
},

Run:

gemini extensions install https://github.com/ProfessionalWiki/MediaWiki-MCP-Server

This installs the extension from the latest GitHub Release. To pin a specific version, append --ref=<tag> (for example --ref=v0.6.5).

See the Gemini CLI extensions documentation for how to update, list, or uninstall extensions.

Deployment

Running the server as a remote HTTP endpoint for other users has its own configuration requirements — see docs/deployment.md. A pre-built image is published at ghcr.io/professionalwiki/mediawiki-mcp-server. For day-2 operations (logs, /health//ready, metrics, graceful shutdown), see docs/operations.md.

Security

Defaults are safe for single-user use. Before exposing the HTTP transport to others, lock down three things:

Trust the proxy, not the header. The server forwards any Authorization: Bearer header straight to MediaWiki — authentication is the reverse proxy's job. Terminate TLS there, and don't expose the MCP port directly on an untrusted network. See docs/deployment.md — security checklist.
Pair MCP_BIND with MCP_ALLOWED_HOSTS and MCP_ALLOWED_ORIGINS. The HTTP transport binds to 127.0.0.1 by default. When you open it up with MCP_BIND=0.0.0.0, set MCP_ALLOWED_HOSTS to the hostnames your proxy forwards and MCP_ALLOWED_ORIGINS to the browser origins allowed to call the server — these block DNS-rebinding and cross-origin attacks respectively.
Uploads are opt-in. upload-file is disabled until you list allowed directories in uploadDirs or MCP_UPLOAD_DIRS. See docs/configuration.md — upload directories.
Internal destinations need MCP_TRUSTED_HOSTS. Outbound fetches — the anonymous siteinfo probe, wiki discovery, *-file-from-url — are SSRF-guarded: a destination resolving to a private or loopback address is refused. To deliberately run against an internal host — e.g. a Docker-network alias like mediawiki.svc that bypasses your public proxy — list it in MCP_TRUSTED_HOSTS to exempt it from the public-IP check. The host is still resolved and pinned, and the guard stays on for every other destination. This is the outbound counterpart to the inbound MCP_ALLOWED_HOSTS (Host-header) check — the two are unrelated despite the similar names.

Report a vulnerability via GitHub's security advisory form — full policy in SECURITY.md.
