Shipped 5 L402 Lightning payment adapters for AI agent frameworks this week:

npm install @powforge/mcp-l402-gate # MCP server middleware
npm install @powforge/mcp-tool-l402 # @modelcontextprotocol/sdk per-tool
npm install @powforge/langchain-l402-middleware # LangChain wrapWithL402
npm install @powforge/semantic-kernel-l402 # Semantic Kernel wrapper
npm install @powforge/paymcp-l402-provider # paymcp BasePaymentProvider backend

Same pattern across all five: agent hits your tool, gets a 402 with a Lightning invoice, pays, replays, tool body runs. Your LNBits backend, your pricing.

Also shipped @powforge/l402-verify — standalone verifier extracted for x402 Foundation contributors. Zero deps, bring-your-own checkPaidFn.

All MIT. powforge.dev/mcp for docs.
