Only coding tools, because that is the category of application the protocol was designed around from the beginning.
Only applications from the vendor that publishes the protocol, since that vendor controls which servers are accepted.
Any client that implements the protocol, because support for it is broad across clients and servers alike.Correct answer
Only the host it was developed against, since each application expects servers written specifically for it.

Show answer & explanation

Correct answer: C. Any client that implements the protocol, because support for it is broad across clients and servers alike.

Explanation

The principle — The payoff of a standard is that the work is done once and reused by everyone who implements it.

Why the key is correct — MCP is an open protocol supported across a wide range of clients and servers. A server written against the specification is not written against a host; the host is whatever happens to connect to it.

Why the others are wrong — Per-host servers are exactly what a standard removes. Coding tools were early adopters rather than the boundary. And an open protocol has no gatekeeper deciding which servers may connect.

Remember this — Write the server against the protocol, and the hosts take care of themselves.
