MediaWiki MCP Server

MediaWiki MCP Server

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

Features

Tools

Resources

mcp://wikis/{wikiKey} — per-wiki resource exposing sitename, server, 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.

{
  "resources": [
    {
      "uri": "mcp://wikis/en.wikipedia.org",
      "name": "wikis/en.wikipedia.org",
      "title": "Wikipedia",
      "description": "Wiki \"Wikipedia\" hosted at https://en.wikipedia.org"
    }
  ]
}

{
  "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

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.

Basic structure

{
  "allowWikiManagement": true,
  "defaultWiki": "en.wikipedia.org",
  "wikis": {
    "en.wikipedia.org": {
      "sitename": "Wikipedia",
      "server": "https://en.wikipedia.org",
      "articlepath": "/wiki",
      "scriptpath": "/w",
      "token": null,
      "username": null,
      "password": null,
      "private": false
    }
  }
}

Configuration fields

Wiki configuration fields

Environment variable substitution (${VAR}), secret sources that read from a password manager, and the plaintext-warning behavior are covered in docs/configuration.md.

Authentication

Tools marked 🔐 require authentication.

OAuth2 (preferred)

1. Navigate to Special:OAuthConsumerRegistration/propose/oauth2 on your wiki.
2. Select "This consumer is for use only by [YourUsername]".
3. Grant the permissions your tools need — see the Permissions column in the Tools table.
4. After approval, copy the Access Token into the token field for that wiki in config.json.

OAuth2 requires the OAuth extension on the wiki.

Bot password (fallback)

If the OAuth extension isn't available, create a bot password at Special:BotPasswords and set username and password in config.json instead of token.
