Show HN: StellarMCP – Free MCP Tools for Claude and Other LLMs

I built a collection of small, useful MCP tools that give LLMs real-world capabilities.

Tools include: DNS lookups, WHOIS, domain age/authority checks, weather, currency conversion, unit conversion, QR code generation, timezone handling, and more.

Free: 10 requests/hour per IP Free with login: 60 requests/hour (OAuth via GitHub/Google)

No paid tier, no credit card. Just add stellarmcp.com/mcp to your Claude config and the tools are available.

Happy to answer questions about the implementation or MCP protocol.
