What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: 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.), PORT (Port used for StreamableHTTP transport). The author declared them in the registry entry; get the values from the project itself.
