What is mediawiki-mcp CLAUDE.md?

Developer instructions for a server that connects coding agents to multiple MediaWiki sites, a platform for collaboratively edited websites. They describe its architecture, authentication, configuration, and two deployment paths: a Claude Code plugin and a LibreChat container.

Use it when developing, configuring, releasing, or deploying the MediaWiki server, especially when changing its entry points, authentication, environment variables, or deployment files.

It helps contributors change the server without breaking either way users run it or losing per-user attribution in LibreChat.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00791	$0.00791
Opus 5.5	$0.00316	$0.00316
Sonnet 5.5	$0.00158	$0.00158
Haiku 4.5	$0.00079	$0.00079

Security

Grade A, and why

mediawiki-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

mediawiki-mcp

Multi-wiki MediaWiki MCP server. Published to npm as mediawiki-mcp.

Dual deployment — do not break either path

This server ships through two channels and both must keep working:

Claude Code plugin marketplace (ttpears/claude-plugins)
- .claude-plugin/plugin.json declares mcpServers.mediawiki → npx -y mediawiki-mcp.
- Entry point is dist/index.js (the bin in package.json) which runs src/stdio.ts.
- Config comes from env vars inherited from the Claude Code process.
- Changes here ship via npm publish (see .github/workflows/release.yml); the marketplace pulls the new version automatically on next npx spawn.
- Keep plugin.json version in sync with package.json version when releasing.
LibreChat (https://www.librechat.ai/docs/features/mcp)
- Runs as a sidecar container via docker-compose.override.yml, started with npm run start:http → src/http-transport.ts.
- LibreChat connects with type: streamable-http, url: http://mediawiki-mcp:8009/mcp.
- Reads a LibreChat session user header on every request (see commit 643aeae) for per-user attribution — don't regress this by caching user identity at session init.
- Host defaults to 0.0.0.0, port MEDIAWIKI_MCP_PORT (default 8009).

Rule of thumb: any refactor to transport, auth, or tool registration must be exercised against both src/stdio.ts and src/http-transport.ts. Tool definitions live in src/tools/ and are shared — keep them transport-agnostic.

Architecture

src/index.ts — stdio entry (used by npx / plugin)
src/http-transport.ts — streamable-HTTP entry (used by LibreChat)
src/wiki-orchestrator.ts — routing + fan-out across registered wikis
src/wiki-registry.ts — env parsing (MEDIAWIKI_WIKIS, per-wiki creds)
src/clients/rest-client.ts — /rest.php/v1/ (MW 1.42+)
src/clients/action-client.ts — /api.php + bot-password login, shared cookie session
src/tools/*.ts — tool implementations, registered via src/tools/index.ts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
