FAQ
Is this really free? No API key?
Yes. Wikipedia's API is public and requires no authentication. The free tier gives you 50 queries/month through this MCP server.
Which clients does it work with?
Claude Desktop, Cursor, VS Code, Windsurf, Continue.dev, and any MCP-compatible client. Three-line JSON config to add.
How is this different from hitting the Wikipedia API directly?
Agent-friendly markdown output, automatic truncation with guidance, category filtering, error recovery with actionable next steps, and full MCP protocol compliance.
Which languages are supported?
300+ Wikipedia language editions from Afrikaans to Zulu. Use the language parameter on any tool (e.g., language="ja" for Japanese).
