Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

Unofficial MCP Builder
Author and maintain unofficial MCP servers for third-party APIs that don't ship one. Generate a server from the vendor's API docs verified against the live API with your own key, detect upstream drift on a schedule, and smoke-test against real operations. Bound by a committed api-surface.yaml recording what the API actually does versus what its docs claim. Publishes to npm.
