The passage around this formula
That parallel is precise enough to formalize, and doing so exposes the actual economic assumption both protocols are making rather than merely asserting it. Let M be the number of distinct hosts — editors, for LSP; agent frameworks and model-serving applications, for MCP — and N be the number of distinct targets — languages, for LSP; tools and data sources, for MCP. Wiring every host to every target independently, the way plugins and early framework wrappers did, requires . separate integrations, because nothing built for one pair transfers to any other. A protocol that both sides implement exactly once instead collapses this to
Learn the underlying idea
Multiplication scales one quantity by another. A dot, a cross, or adjacent symbols can indicate a product.
