Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`CONFIG` Optional	Path to your configuration file
`MCP_ALLOW_STATIC_FALLBACK` Optional	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` Optional	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` Optional	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` Optional	Minimum severity for logger output (stderr telemetry and sendLoggingMessage broadcast). Invalid values fail loudly on first log call.
`MCP_MAX_REQUEST_BODY` Optional	Maximum HTTP request body size on the StreamableHTTP transport. Accepts size strings like 1mb or 512kb.
`MCP_METRICS` Optional	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` Optional	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 client…
`MCP_OAUTH_CIMD_ALLOWED_HOSTS` Optional	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` Optional	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` Optional	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` Optional	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` Optional	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` Optional	Maximum milliseconds to wait for in-flight /mcp calls to drain on SIGTERM/SIGINT before exiting. Capped at 600000.
`MCP_TRANSPORT` Optional	Type of MCP server transport
`MCP_UPLOAD_MAX_BYTES` Optional	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` Optional	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 ([email protected])'.
`PORT` Optional	Port used for StreamableHTTP transport
