MCP Doesn't Suck. Your Agent Does. — Jan Čurn, Apify
Naive agents pre-loading all MCP tools waste context before any work begins
“Maybe a third of your context disappeared before you even started doing any work.”
Apify CEO Jan Čurn argues the wave of MCP criticism is misplaced — the protocol is sound, but agent implementations are naive, registering all tools from all MCP servers into context upfront and consuming up to a third of the available context window before processing a single user query. The talk reframes the MCP debate from a protocol problem to an agent design problem. This matters because it offers a concrete diagnosis for why MCP-powered agents underperform and points toward smarter tool-loading strategies as the fix.
