A side-by-side look at the Fabler x402 Tools and Quantum Readiness Scan MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Fabler x402 Tools for finance & fintech work over a hosted endpoint; choose Quantum Readiness Scan for finance & fintech as a local process. You can also run both side by side in one mcpServers block.
