What Mcp Leaf does
Codec is the substrate that lets gateways, routers, agents, tool dispatchers, and observers operate on raw token IDs end-to-end. No detokenize on the hot path. No JSON-parse per token. No UTF-8 round-trip at every hop. Compression and wire reduction are byproducts of the framing — what you actually buy is the ability to run the inference layer like infrastructure.
