}Registry/plugin listing metadata for InvoiceHub's hosted
MCP server. There's no local package here — the server itself is a hosted
Streamable HTTP endpoint at https://api.invoicehub.dev/mcp, implemented in the
main einvoice-dev1/einvoice monorepo
(packages/api/src/mcp.ts). This repo exists to give that endpoint a public
server.json and Claude Code plugin manifest, since MCP registries and the
plugin marketplace require a public repository to list against.
