What the publisher says

From the MediaWiki MCP Server repository's README, as published. We do not edit it. Read it on GitHub

MediaWiki MCP Server

An MCP (Model Context Protocol) server that enables Large Language Model (LLM) clients to interact with any MediaWiki wiki.

Features

Tools

Every tool that operates on a wiki accepts an optional wiki argument naming the wiki to act on (the wiki-management and OAuth tools do not) — pass a wiki key (e.g. en.wikipedia.org) or the full mcp://wikis/{wikiKey} URI. Omit it to use the configured default wiki (see Configuration). Each tool response reports the wiki the call ran against. Each successful response carries its payload as prose in content and as JSON in structuredContent; see response channels.

Credentials it needs

CONFIGPath to your configuration file
MCP_ALLOW_STATIC_FALLBACKSet 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_BYTESByte 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_BYTESHard 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_LEVELMinimum severity for logger output (stderr telemetry and sendLoggingMessage broadcast). Invalid values fail loudly on first log call.
MCP_MAX_REQUEST_BODYMaximum HTTP request body size on the StreamableHTTP transport. Accepts size strings like 1mb or 512kb.
MCP_METRICSSet to 'true' to expose Prometheus metrics at GET /metrics on the HTTP transport. Has no effect on the stdio transport.
MCP_OAUTH_ALLOWED_REDIRECTSAdditional 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_HOSTSComma-separated additional client_id document hosts trusted for CIMD (bare host or host:port). Verified first-party hosts are always trusted.
MCP_OAUTH_CREDENTIALS_FILEOverride 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_BROWSERSet 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_FILEPath 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_URLOverride 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_MSMaximum milliseconds to wait for in-flight /mcp calls to drain on SIGTERM/SIGINT before exiting. Capped at 600000.
MCP_TRANSPORTType of MCP server transport
MCP_UPLOAD_MAX_BYTESMemory 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_AGENTReplaces 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)'.
