Resources

mcp://wikis/{wikiKey}

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

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

{
  "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, and : with - (e.g. make dev-inspector).

MCP Inspector

To start the development server and the MCP Inspector:

npm run dev:inspector

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 and Dockerfile (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
