endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

pypi package mcp-billing-gateway - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.sapph1re is GitHub-verified and matches the repo owner
