up to 50 results per call\n\n---\n\n### `wikipedia_get_languages`\n\nList language editions available for a Wikipedia article.\n\n- Returns language codes, article titles in each language, and full URLs\n- Use for cross-language research or to discover a non-English title before switching editions\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool definitions — single file per tool, framework handles registration and validation\n- Unified error handling — handlers throw, framework catches, classifies, and formats\n- Pluggable auth: `none`, `jwt`, `oauth`\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- STDIO and Streamable HTTP transports\n\nWikipedia-specific:\n\n- Dual API integration — MediaWiki REST API (`/api/rest_v1/`) for summaries, Action API (`/w/api.php`) for search, full text, sections, geo search, and language links\n- Retry and backoff on all requests; `User-Agent` header per Wikimedia API policy\n- Wikitext stripping pipeline via `wtf_wikipedia` — handles links, templates, refs, bold/italic; re-injects section headings for structure\n- Per-call `language` parameter on every tool — all Wikipedia language editions accessible in a single session\n- Language validation against ~250 known Wikipedia edition codes — catches structurally valid but nonexistent editions before they cause timeouts\n\nAgent-friendly output:\n\n- `page_type` field on summaries discriminates article / disambiguation / redirect — no string parsing needed\n- `wikibase_item` (Wikidata QID) on summaries enables direct cross-referencing with wikidata-mcp-server\n- `section_index` on table-of-contents entries links directly to the targeted-read parameter on `wikipedia_get_article`\n- Recovery hints on every error type — callers get actionable next steps (e.g., \"use `wikipedia_search` to find the correct title\")\n\n## Getting started\n\nAdd the following to your MCP client configuration file.\n\n```json\n{\n  \"mcpServers\": {\n    \"wikipedia\": {\n      \"type\": \"stdio\",\n      \"command\": \"bunx\",\n      \"args\": [\"wikipedia-mcp-server@latest\"],\n      \"env\": {\n        \"MCP_TRANSPORT_TYPE\": \"stdio\",\n        \"MCP_LOG_LEVEL\": \"info\"\n      }\n    }\n  }\n}\n```\n\nOr with npx (no Bun required):\n\n```json\n{\n  \"mcpServers\": {\n    \"wikipedia\": {\n      \"type\": \"stdio\",\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"wikipedia-mcp-server@latest\"],\n      \"env\": {\n        \"MCP_TRANSPORT_TYPE\": \"stdio\",\n        \"MCP_LOG_LEVEL\": \"info\"\n      }\n    }\n  }\n}\n```\n\nOr with Docker:\n\n```json\n{\n  \"mcpServers\": {\n    \"wikipedia\": {\n      \"type\": \"stdio\",\n      \"command\": \"docker\",\n      \"args\": [\n        \"run\", \"-i\", \"--rm\",\n        \"-e\", \"MCP_TRANSPORT_TYPE=stdio\",\n        \"ghcr.io/cyanheads/wikipedia-mcp-server:latest\"\n      ]\n    }\n  }\n}\n```\n\nFor Streamable HTTP, set the transport and start the server:\n\n```sh\nMCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http\n# Server listens at http://localhost:3010/mcp\n```\n\n### Prerequisites\n\n- [Bun v1.3.0](https://bun.sh/) or higher (or Node.js v24+).\n- No API keys required — Wikipedia's API is public.\n\n### Installation\n\n1. **Clone the repository:**\n\n```sh\ngit clone https://github.com/cyanheads/wikipedia-mcp-server.git\n```\n\n2. **Navigate into the directory:**\n\n```sh\ncd wikipedia-mcp-server\n```\n\n3. **Install dependencies:**\n\n```sh\nbun install\n```\n\n4. **Configure environment (optional):**\n\n```sh\ncp .env.example .env\n# edit .env if you want to customize WIKIPEDIA_USER_AGENT or logging\n```\n\n## Configuration\n\n| Variable | Description | Default |\n|:---------|:------------|:--------|\n| `WIKIPEDIA_USER_AGENT` | User-Agent header sent with every Wikimedia API request. Customize for your deployment. | `wikipedia-mcp-server/0.1.6 (https://github.com/cyanheads/wikipedia-mcp-server)` |\n| `WIKIPEDIA_BASE_URL` | Base Wikipedia URL. Language selection is per-call — not a global language setting. | `https://en.wikipedia.org` |\n| `MCP_TRANSPORT_TYPE` | Transport: `stdio` or `http`. | `stdio` |\n| `MCP_HTTP_PORT` | Port for HTTP server. | `3010` |\n| `MCP_AUTH_MODE` | Auth mode: `none`, `jwt`, or `oauth`. | `none` |\n| `MCP_LOG_LEVEL` | Log level (RFC 5424). | `info` |\n| `LOGS_DIR` | Directory for log files (Node.js only). | `\u003cproject-root\u003e/logs` |\n| `OTEL_ENABLED` | Enable OpenTelemetry instrumentation (spans, metrics, completion logs). | `false` |\n\nSee [`.env.example`](./.env.example) for the full list of optional overrides.\n\n## Running the server\n\n### Local development\n\n- **Build and run:**\n\n  ```sh\n  # One-time build\n  bun run rebuild\n\n  # Run the built server\n  bun run start:stdio\n  # or\n  bun run start:http\n  ```\n\n- **Run checks and tests:**\n\n  ```sh\n  bun run devcheck   # Lint, format, typecheck, security\n  bun run test       # Vitest test suite\n  bun run lint:mcp   # Validate MCP definitions against spec\n  ```\n\n### Docker\n\n```sh\ndocker build -t wikipedia-mcp-server .\ndocker run --rm -p 3010:3010 wikipedia-mcp-server\n```\n\nThe Dockerfile defaults to HTTP transport, stateless session mode, and logs to `/var/log/wikipedia-mcp-server`. OpenTelemetry peer dependencies are installed by default — build with `--build-arg OTEL_ENABLED=false` to omit them.\n\n## Project structure\n\n| Directory | Purpose |\n|:----------|:--------|\n| `src/index.ts` | `createApp()` entry point — registers tools and inits the Wikipedia service. |\n| `src/config` | Server-specific environment variable parsing and validation with Zod. |\n| `src/mcp-server/tools` | Tool definitions (`*.tool.ts`) — one file per tool. |\n| `src/services/wikipedia` | WikipediaService — REST API + Action API client with retry/backoff and language validation. |\n| `tests/` | Unit and integration tests mirroring `src/`. |\n\n## Development guide\n\nSee [`CLAUDE.md`](./CLAUDE.md) for development guidelines and architectural rules. The short version:\n\n- Handlers throw, framework catches — no `try/catch` in tool logic\n- Use `ctx.log` for request-scoped logging, `ctx.state` for tenant-scoped storage\n- Register new tools in `src/mcp-server/tools/definitions/index.ts`\n- Wrap external API calls: validate raw → normalize to domain type → return output schema; never fabricate missing fields\n\n## Contributing\n\nIssues and pull requests are welcome. Run checks and tests before submitting:\n\n```sh\nbun run devcheck\nbun run test\n```\n\n## License\n\nApache-2.0 — see [LICENSE](LICENSE) for details.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcyanheads%2Fwikipedia-mcp-server","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcyanheads%2Fwikipedia-mcp-server","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcyanheads%2Fwikipedia-mcp-server/lists"}
