A good MCP server makes the difference between an agent using 20k tokens and 2 million. It may not matter yet with sponsored Codex and Claude subscriptions, but it will kill many use cases once providers switch to token-based billing.

That may sound like an exaggeration, but it’s exactly what I see in our product.

Humans developing something already have context that agents don’t have yet. Most agents start a task with virtually no prior knowledge. And they start from zero every single time. That may improve in the future, but we’re not there yet.

Can agents get the job done? Yes. But without a thoughtfully implemented MCP server, they are awkwardly inefficient.
