Install MediaWiki MCP server

claude mcp add mediawiki-professionalwiki -- npx -y @professional-wiki/mediawiki-mcp-server

{
  "mcpServers": {
    "mediawiki-professionalwiki": {
      "command": "npx",
      "args": [
        "-y",
        "@professional-wiki/mediawiki-mcp-server"
      ]
    }
  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "mediawiki-professionalwiki": {
      "command": "npx",
      "args": [
        "-y",
        "@professional-wiki/mediawiki-mcp-server"
      ]
    }
  }
}

Settings → Developer → Edit Config (claude_desktop_config.json), then restart.

{
  "servers": {
    "mediawiki-professionalwiki": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@professional-wiki/mediawiki-mcp-server"
      ]
    }
  }
}

Add to .vscode/mcp.json in your workspace.

{
  "mcpServers": {
    "mediawiki-professionalwiki": {
      "command": "npx",
      "args": [
        "-y",
        "@professional-wiki/mediawiki-mcp-server"
      ]
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json.

Configuration

Variable	Required	Secret	Description
CONFIG	—	—	Path to your configuration file
MCP_ALLOW_STATIC_FALLBACK	—	—	Set to 'true' to allow HTTP startup when config.json has static credentials. Otherwise the server refuses to start, preventing silent shared-identity fallback for unauthenticated requests.
MCP_CONTENT_MAX_BYTES	—	—	Byte cap for the content bodies and result blocks tools return (wikitext, rendered HTML, diffs, statement and row listings). An oversized response is truncated with a trailing marker describing what was left out.
MCP_FILE_DATA_MAX_BYTES	—	—	Hard cap on the base64-encoded size of a get-file-data response. A transport/safety backstop; callers tune actual size with the tool's width parameter. Over-cap responses error rather than truncate.
MCP_LOG_LEVEL	—	—	Minimum severity for logger output (stderr telemetry and sendLoggingMessage broadcast). Invalid values fail loudly on first log call.
MCP_MAX_REQUEST_BODY	—	—	Maximum HTTP request body size on the StreamableHTTP transport. Accepts size strings like 1mb or 512kb.
MCP_METRICS	—	—	Set to 'true' to expose Prometheus metrics at GET /metrics on the HTTP transport. Has no effect on the stdio transport.
MCP_OAUTH_ALLOWED_REDIRECTS	—	—	Additional allowed redirect URIs for hosted-proxy client registration: comma-separated exact URIs (which must include a host) and https prefix patterns ending in /*. Loopback, claude.ai, and verified first-party clients (ChatGPT, Cursor, VS Code) are always allowed; unset means no additional clients.
MCP_OAUTH_CIMD_ALLOWED_HOSTS	—	—	Comma-separated additional client_id document hosts trusted for CIMD (bare host or host:port). Verified first-party hosts are always trusted.
MCP_OAUTH_CREDENTIALS_FILE	—	—	Override the default OAuth credentials store path. Default: ~/.config/mediawiki-mcp/credentials.json on Linux/macOS, %APPDATA%\mediawiki-mcp\credentials.json on Windows.
MCP_OAUTH_NO_BROWSER	—	—	Set to '1' to skip launching a browser during the OAuth dance and log the auth URL to stderr instead. Useful in headless environments and CI.
MCP_OAUTH_PROXY_STORE_FILE	—	—	Path to the hosted OAuth proxy's encrypted state file, which lets sign-ins survive restarts. Default: proxy-store.enc under the mediawiki-mcp config dir; /app/data/proxy-store.enc in the Docker image.
MCP_PUBLIC_URL	—	—	Override the request-derived public URL used in the protected-resource discovery doc and WWW-Authenticate header. Set this when running behind a proxy that rewrites the request Host.
MCP_SHUTDOWN_GRACE_MS	—	—	Maximum milliseconds to wait for in-flight /mcp calls to drain on SIGTERM/SIGINT before exiting. Capped at 600000.
MCP_TRANSPORT	—	—	Type of MCP server transport
MCP_UPLOAD_MAX_BYTES	—	—	Memory cap on the server-side fetch used by upload-file-from-url and update-file-from-url. Files larger than this are routed to the wiki's own copy-upload instead of being buffered by the server. Guards this server's memory, not the wiki's $wgMaxUploadSize.
MCP_USER_AGENT	—	—	Replaces the User-Agent header of every outbound request, which defaults to mediawiki-mcp-server/<version> (https://github.com/ProfessionalWiki/MediaWiki-MCP-Server). If you set it, give a name and an email or URL, e.g. 'ExampleBot/1.0 (bot@example.org)'.
PORT	—	—	Port used for StreamableHTTP transport
