MCP server enabling AI clients to interact with any MediaWiki wiki through standard tools

In-path gate · all MCP tools

Using MediaWiki MCP Server in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

uv tool install mcpindex-gate && mcpindex-config-wire

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).

Contracts can change after screening, with no version bump. The gate pins MediaWiki MCP Server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

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 for unauthenticated requests.

MCP_CONTENT_MAX_BYTES

Byte cap for content bodies (wikitext, rendered HTML, diffs) returned by get-page, get-pages, parse-wikitext, and compare-pages. Oversized bodies are truncated with a trailing marker.

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

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 960,209). Verify it yourself.
