MediaWiki MCP Server

professionalwiki/mediawiki-mcp-server

Connects Claude to any MediaWiki instance through the Model Context Protocol, exposing read and write operations on pages, files, categories, and revision history. You get tools for diffing revisions, searching content, parsing wikitext, and managing pages with proper permission scopes. Supports OAuth2 for write operations and handles multiple wikis in a single session. Extension-aware tooling lights up automatically when it detects Cargo, Semantic MediaWiki, or Bucket on the target wiki. Particularly useful if you're building workflows that need programmatic access to Wikipedia, internal company wikis, or any MediaWiki deployment without writing custom API wrappers.

Configuration

CONFIGdefault: config.json

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_BYTESdefault: 75000

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_BYTESdefault: 1000000

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_LEVELdefault: debug

Minimum severity for logger output (stderr telemetry and sendLoggingMessage broadcast). Invalid values fail loudly on first log call.

MCP_MAX_REQUEST_BODYdefault: 1mb

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 n

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_MSdefault: 10000

Maximum milliseconds to wait for in-flight /mcp calls to drain on SIGTERM/SIGINT before exiting. Capped at 600000.

MCP_TRANSPORTdefault: stdio

Type of MCP server transport

MCP_UPLOAD_MAX_BYTESdefault: 104857600

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

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 (bot@example.org)'.

PORTdefault: 3000

Port used for StreamableHTTP transport
