Config formats checked against the official docs on 2026-10-07.

## Environment variables

- `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…
- `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…
- `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…
- `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…
- `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` (secret): Override the default OAuth credentials store path. Default: ~/.config/mediawiki-mcp/credentials.json on Linux/macOS, %APPDATA%\mediawiki-mcp\credentials.json…
- `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…
- `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…
- `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…
- `MCP_USER_AGENT`: Replaces the User-Agent header of every outbound request, which defaults to mediawiki-mcp-server/ (https://github.com/ProfessionalWiki/MediaWiki-MCP-Server)…
- `PORT`: Port used for StreamableHTTP transport
