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

{
  "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

Field	Description
defaultWiki	The default wiki identifier to use (matches a key in wikis)
wikis	Object containing wiki configurations, keyed by domain/identifier

Wiki configuration fields

Field	Required	Description
sitename	Yes	Display name for the wiki
server	Yes	Base URL of the wiki (e.g., https://en.wikipedia.org)
articlepath	Yes	Path pattern for articles (typically /wiki)
scriptpath	Yes	Path to MediaWiki scripts (typically /w)
token	No	OAuth2 access token for authenticated operations (preferred)
username	No	Bot username (fallback when OAuth2 is not available)
password	No	Bot password (fallback when OAuth2 is not available)
private	No	Whether the wiki requires authentication to read (default: false)

Authentication setup

For tools marked with 🔐, authentication is required.

Preferred method: OAuth2 Token

1. Navigate to Special:OAuthConsumerRegistration/propose/oauth2 on your wiki
2. Select "This consumer is for use only by [YourUsername]"
3. Grant the necessary permissions
4. After approval, you'll receive:
   • Client ID
   • Client Secret
   • Access Token
5. Add the token to your wiki configuration in config.json

Note: OAuth2 requires the OAuth extension to be installed on the wiki.

Fallback method: Username & Password

If OAuth2 is not available on your wiki, you can use bot credentials (from Special:BotPasswords ) instead of the OAuth2 token.

Development

🐋 Develop with Docker: Replace the npm run part of the command with make (e.g. make dev).

MCP Inspector

To start the development server and the MCP Inspector:

npm run dev

The command will build and start the MCP Proxy server locally at 6277 and the MCP Inspector client UI at http://localhost:6274.

Test with MCP clients

To enable your MCP client to use this MediaWiki MCP Server for local development:

1. Install the MCP server on your MCP client.

2. Change the command and args values as shown in the mcp.json file (or mcp.docker.json if you prefer to run the MCP server in Docker).

3. Run the watch command so that the source will be compiled whenever there is a change:

   npm run watch
   

Release process

To release a new version:

# For patch release (0.1.1 → 0.1.2)
npm version patch

# For minor release (0.1.1 → 0.2.0)
npm version minor

# For major release (0.1.1 → 1.0.0)
npm version major

# Or specify exact version
npm version 0.2.0

This command automatically:

• Updates package.json and package-lock.json
• Syncs the version in server.json (via the version script)
• Creates a git commit
• Creates a git tag (e.g., v0.2.0)

git push origin master --follow-tags

1. Go to the Releases page
2. Click "Create a new release"
3. Select the tag you just pushed (e.g., v0.2.0)
4. Add a title and release notes
5. Click "Publish release"

The GitHub Actions workflow will automatically:

• Build and publish to NPM
• Publish to the MCP Registry
