Enum Transport 

pub enum Transport {
    Stdio,
    Tcp,
    Http,
}

Wire transport the server listens on. The JSON-RPC/MCP semantics are identical across all three — only the framing differs.

Variants

Stdio

Newline-delimited JSON-RPC over stdin/stdout (default; for Claude Desktop / Claude Code and other process-spawning clients).

Tcp

Newline-delimited JSON-RPC over a TCP socket (one message per line), accepting many concurrent connections.

Http

MCP Streamable HTTP: POST JSON-RPC to /mcp (responses as JSON or, when the client Accepts it, an SSE stream), plus GET /mcp for a standalone server→client SSE stream.

Trait Implementations

impl Clone for Transport

fn clone(&self) -> Transport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Transport

impl Debug for Transport

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Transport

impl PartialEq for Transport

fn eq(&self, other: &Transport) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Transport

impl ValueEnum for Transport

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
