Struct StdioClientTransport

pub struct StdioClientTransport { /* private fields */ }

STDIO transport for MCP clients

This transport communicates with an MCP server via STDIO (standard input/output). It’s typically used when the server is a separate process.

Implementations

impl StdioClientTransport

pub async fn new<S: AsRef<str>>(command: S, args: Vec<S>) -> McpResult<Self>

Create a new STDIO client transport

Arguments

• command - Command to execute for the MCP server
• args - Arguments to pass to the command

Returns

Result containing the transport or an error

pub async fn with_config<S: AsRef<str>>( command: S, args: Vec<S>, config: TransportConfig, ) -> McpResult<Self>

Create a new STDIO client transport with custom configuration

Arguments

• command - Command to execute for the MCP server
• args - Arguments to pass to the command
• config - Transport configuration

Returns

Result containing the transport or an error
