A practical teardown of Model Context Protocol shows how bad skill descriptions and sloppy names stop tool calls cold, with parameter schemas and activation logic being the usual failure modes; a one-line MCP tool and Java TCP/Spring MVC endpoints get wired to Claude-style models and lift activation from 30%→90% activation (a ~3x uplift) after renaming and better JSON schema; notes compare RPC-over-HTTP to plain HTTP+JSON and point to MCP naming and eval artifacts.
