LND now supports MPP, with the latest lnget release, you can use both L402 and the Machine Payments Protocol for agentic payments on Lightning.
lnget auto-detects what the server supports and pays in the same request. One tool that supports both protocols.
This release also includes an agent-native CLI with JSON i/o, MCP server support, and context management features.
Reading this initially, I thought this was about Multipath payments (which have been supported for quite a while)
