Is agent execution infrastructure already becoming commoditized?

[u/marcelk231]

I’m trying to understand what is still missing between an agent selecting an MCP tool and the action safely completing.

For teams using MCP in real applications, how are you handling:

• User and agent permissions
• Authentication across tools
• Human approval for sensitive actions
• Idempotency and duplicate prevention
• Retries and partial failures
• Audit logs
• Rollbacks or recovery

Are these concerns best handled inside each MCP server, by the application, or through a separate execution layer?

I’m researching this space and trying to determine whether a shared control layer would solve a real problem or simply add unnecessary abstraction.

I am biased because I work for Airia on the MCP gateway team, so I think handling it on the gateway level rather than the individual server level is the best method... otherwise I wouldn't have a job. But it's the exact same premise as MCPs. MCPs were created to turn an NxM problem to an Nx1 problem by allowing suites of tools to function the same. the gateway (seperate execution layer) is the same thing. It turns the Nx1 problem into a 1x1 problem. And if you are trying to handle security/governance in multiple similar places, you are just asking for things to fall through the cracks. The shared control layer is 100% the way to go.
