Developer slams MCP: like GraphQL, too open-ended, hard to cache and easy to attack
ZeroCool86 · reddit · 2026-10-22
A developer who runs an MCP server published a rant arguing MCP mirrors what was wrong with GraphQL: too open-ended, hard to cache, easy to attack, with auth bolted on and everything verbose. After measuring MCP implementations across tools, he "could not find many redeeming qualities." His biggest gripe: MCP ignores well-established web standards and reinvents them poorly, while inefficient implementations burn tokens, time, and API costs. He admits some blame lies with implementers and offers no alternative, but the post captures real community skepticism about the protocol.
