Enum TransportArgs 

pub enum TransportArgs {
    Stdio {
        command: String,
        args: Vec<String>,
        env: Vec<String>,
        cwd: Option<String>,
    },
    Http {
        url: String,
        headers: Vec<String>,
    },
    Sse {
        url: String,
        headers: Vec<String>,
    },
}

CLI-flag mirror of McpTransport, holding the raw, unvalidated Option/Vec<String> values clap hands back.

Every variant is a legal state by construction — there is no all-None or “both http and sse” shape to represent, unlike the flat flag surface this type is built from. In the real CLI path, values come from TryFrom<ServerFlags> for ServerSource, the single place “exactly one transport selected” is enforced (backed by clap’s server_source argument group at parse time); since this type and its fields are pub, a direct caller can also construct one by hand (e.g. as a library), which is exactly why every variant already being well-formed matters. TryFrom<TransportArgs> for McpTransport does the KEY=VALUE parsing for environment variables and headers.

Examples

use mcp_execution_cli::commands::common::TransportArgs;

let transport = TransportArgs::Stdio {
    command: "github-mcp-server".to_string(),
    args: vec!["stdio".to_string()],
    env: vec![],
    cwd: None,
};
assert!(matches!(transport, TransportArgs::Stdio { .. }));

Debug output redacts env/headers entries wholesale, not just a value half — these are raw, unparsed KEY=VALUE strings, and per parse_key_value’s own doc comment the whole string may be the secret with no discernible key:

use mcp_execution_cli::commands::common::TransportArgs;

let transport = TransportArgs::Http {
    url: "https://api.example.com/mcp".to_string(),
    headers: vec!["Authorization=Bearer sk-secret".to_string()],
};

let debug_output = format!("{transport:?}");
assert!(!debug_output.contains("sk-secret"));
assert!(!debug_output.contains("Authorization"));
assert!(debug_output.contains("<redacted>"));
