MediaWiki: MCP server, setup and security

What MediaWiki does

According to its repository: “Connect to any MediaWiki wiki (Wikipedia, Fandom, corporate wikis) to search, read and edit pages, analyze links, view revision history and convert to Markdown.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. MediaWiki is listed under Memory and knowledge, a category of 250 servers in the directory, where it ranks #141 by stars.

Topics declared by the repository: starred, anthropic, claude, go, golang, mediawiki.

Installing and connecting MediaWiki

Distribution modes declared in the official MCP registry:

• Docker (OCI) image
• MCPB bundle (one-click install in Claude Desktop)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Go. Listed systems: macOS, Windows, Linux.

The registry lists 5 secret variables to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for MediaWiki:

• Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on December 10, 2025, the olgasafonova/mediawiki-mcp-server repository has 22 stars and 8 forks, with 2 open issues. It has more stars than 39% of the servers in the directory. It received changes this month. Version published in the registry: 1.36.0 (October 14, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
