MediaWiki MCP Server

MediaWiki MCP Server is an MCP server that enables LLM clients to interact with any MediaWiki installation using the Model Context Protocol. Built for researchers, wiki administrators, and developers, it bridges AI assistants with public platforms like Wikipedia or private internal MediaWiki sites. The server exposes an extensive toolset for reading and writing content, managing wiki resources, and inspecting site metadata. Users can fetch page contents, inspect revisions, search namespaces, review diffs, and retrieve base64 image data directly within the chat interface. For authenticated setups, it supports operations such as creating, updating, moving, or deleting pages, as well as uploading files. It also features native integrations for popular MediaWiki extension packs, including Semantic MediaWiki, Wikibase, Cargo, Bucket, and NeoWiki, which unlock structured knowledge graphs, Cypher queries, SPARQL queries, and database tables. By supporting multiple configured wikis simultaneously via standard stdio or HTTP transports, the server provides a comprehensive interface for programmatic knowledge base interaction.

How to install and configure MediaWiki MCP Server

1. Ensure Node.js is installed on your system to run the package via @professional-wiki/mediawiki-mcp-server. 2. Create a config.json file configuring your MediaWiki connections, defining your defaultWiki and mapping specific wiki host configurations such as server, articlepath, and scriptpath. 3. Add the server entry into your MCP client configuration file (such as Claude Desktop's claude_desktop_config.json). Configure the server command to execute the package, setting the CONFIG environment variable to point to your config.json path. 4. Optionally specify environment variables such as MCP_TRANSPORT (e.g., stdio), MCP_CONTENT_MAX_BYTES, or OAuth settings if your wiki requires authentication. 5. Save the configuration and restart your MCP client to load the tools and wiki resources.

What you can do with MediaWiki MCP Server

• Researching Wikipedia topics and retrieving raw wikitext, categories, and page revision histories directly within conversational LLM sessions. - Creating and updating internal enterprise wiki articles, documentation pages, and uploaded files using authenticated write tools. - Querying structured semantic databases by running SPARQL, Cargo SQL, or Semantic MediaWiki ask queries through extension packs. - Diffing historical revisions or previewing wikitext-to-HTML rendering without saving changes to verify proposed edits before publishing.
