Keys and settings

The registry record declares settings, none marked secret. Declared by the publisher:

• CONFIG (environment variable, not marked required): Path to your configuration file
• MCP_ALLOW_STATIC_FALLBACK (environment variable, not marked required): Set to 'true' to allow HTTP startup when config.json has static credentials. Otherwise the server refuses to start, preventing silent shared-identity fallback f
• MCP_CONTENT_MAX_BYTES (environment variable, not marked required): Byte cap for the content bodies and result blocks tools return (wikitext, rendered HTML, diffs, statement and row listings). An oversized response is truncated
• MCP_FILE_DATA_MAX_BYTES (environment variable, not marked required): 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
• MCP_LOG_LEVEL (environment variable, not marked required): Minimum severity for logger output (stderr telemetry and sendLoggingMessage broadcast). Invalid values fail loudly on first log call.
• MCP_MAX_REQUEST_BODY (environment variable, not marked required): Maximum HTTP request body size on the StreamableHTTP transport. Accepts size strings like 1mb or 512kb.
• MCP_METRICS (environment variable, not marked required): 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 (environment variable, not marked required): Additional allowed redirect URIs for hosted-proxy client registration: comma-separated exact URIs (which must include a host) and https prefix patterns ending i
• MCP_OAUTH_CIMD_ALLOWED_HOSTS (environment variable, not marked required): 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 (environment variable, not marked required): Override the default OAuth credentials store path. Default: ~/.config/mediawiki-mcp/credentials.json on Linux/macOS, %APPDATA%\mediawiki-mcp\credentials.json on
• MCP_OAUTH_NO_BROWSER (environment variable, not marked required): 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 (environment variable, not marked required): 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/d
• MCP_PUBLIC_URL (environment variable, not marked required): 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 rewr
• MCP_SHUTDOWN_GRACE_MS (environment variable, not marked required): Maximum milliseconds to wait for in-flight /mcp calls to drain on SIGTERM/SIGINT before exiting. Capped at 600000.
• MCP_TRANSPORT (environment variable, not marked required): Type of MCP server transport
• MCP_UPLOAD_MAX_BYTES (environment variable, not marked required): 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 inste
• MCP_USER_AGENT (environment variable, not marked required): Replaces the User-Agent header of every outbound request, which defaults to mediawiki-mcp-server/<version> (https://github.com/ProfessionalWiki/MediaWiki-MCP-Se
• PORT (environment variable, not marked required): Port used for StreamableHTTP transport

Being listed is not a safety check. Read the repository and check what a server asks for before you connect it. How the directory works.
