HTTP proxy hardening
If you run the HTTP proxy (npm run proxy), upgrade.
- The proxy now binds to
127.0.0.1by default. Binding to another interface is an explicit opt-in throughPAYWARE_MCP_PROXY_HOST, and it logs a warning. - Browser requests are accepted only from an allow-list of origins, widened through
PAYWARE_MCP_PROXY_ORIGINS. - The stdio transport, which MCP clients such as Claude Code use by default, opens no port and is unaffected.
Listed in the MCP Registry
The server is published to the official MCP Registry as io.github.payware/mcp-server, with the environment variables it reads described in server.json. Every release now updates the listing automatically after the npm publish.
