Enum ServerStatus 

pub enum ServerStatus {
    Available,
    Unavailable,
}

Status of a configured server.

The precise check behind this depends on the call site: server list uses transport_available (PATH lookup for stdio; URL well-formedness plus a bounded MCP introspection attempt for http/sse — see LIST_AVAILABILITY_TIMEOUT). server info/server validate instead reflect whether a full MCP introspection handshake succeeded, waiting out the entry’s full configured connect_timeout_secs/discover_timeout_secs.

For http/sse, list and info/validate share the exact same connection path (Introspector::discover_server), so they can no longer disagree about how a transport is reached (proxying, IPv6) — only about how long the check is allowed to run. list’s bounded check is a time-boxed, best-effort signal across every configured server; server validate <name>/server info <name> are the authoritative check for one specific server. A server that is merely slow (past list’s short bound but within its own configured timeout) can therefore show unavailable in list and available in validate/info. This is an intentional, documented trade-off — distinct from #280, which was an unconditional wrong answer, not a bounded, best-effort one.

For stdio, this equivalence does not hold: list still performs only a PATH lookup while info/validate perform a full handshake, so the two can disagree about more than timing (pre-existing behavior, unrelated to #280’s http/sse scope).

Examples

use mcp_execution_cli::commands::server::ServerStatus;

assert_eq!(
    serde_json::to_string(&ServerStatus::Available).unwrap(),
    "\"available\""
);
assert_eq!(
    serde_json::to_string(&ServerStatus::Unavailable).unwrap(),
    "\"unavailable\""
);

Variants

Available

list: command in PATH / URL well-formed and reachable. info: introspection succeeded.

Unavailable

list: command missing / URL malformed or unreachable. info: introspection failed.
