What's this about?
An Anthropic engineer argued that modern deferred-tool MCP servers are a better default for most external agent integrations; developers replied that shell commands remain better for some local jobs. This is a design debate, not a settled benchmark.
What exactly are MCP and CLI?
MCP is a standard way to present typed tools and authentication to a model; CLI means invoking ordinary commands in a terminal. Think of an application connector versus a familiar toolbox on your own machine.

- Deferred MCP tools avoid loading every schema into model context at once.
- CLI commands compose naturally into local scripts and pipelines with little setup.
- MCP can handle browser/mobile hosts, multi-user OAuth and audited tool catalogs where no shell exists.
