Struct StdioServerTransport

pub struct StdioServerTransport { /* private fields */ }

STDIO transport for MCP servers

This transport communicates with an MCP client via STDIO (standard input/output). It reads requests from stdin and writes responses to stdout.

Implementations

impl StdioServerTransport

pub fn new() -> Self

Create a new STDIO server transport

Returns

New STDIO server transport instance

pub fn with_config(config: TransportConfig) -> Self

Create a new STDIO server transport with custom configuration

Arguments

• config - Transport configuration

Returns

New STDIO server transport instance

pub fn set_request_handler<F>(&mut self, handler: F)

where F: Fn(JsonRpcRequest) -> Receiver<JsonRpcResponse> + Send + Sync + 'static,

Set the request handler function

Arguments

• handler - Function that processes incoming requests
