Examples

// Simple filesystem server
var options = new StdioTransportOptions
{
    Command = "npx",
    Arguments = "@modelcontextprotocol/server-filesystem /path/to/dir"
};

// Python server with environment variables
var options = new StdioTransportOptions
{
    Command = "python",
    Arguments = "-m my_mcp_server --port 8080",
    WorkingDirectory = "/path/to/server",
    Environment = new Dictionary<string, string>
    {
        ["API_KEY"] = "your-api-key",
        ["DEBUG"] = "true"
    }
};

Remarks

The stdio transport launches an MCP server as a subprocess and communicates via standard input (stdin) and standard output (stdout) using newline-delimited JSON (JSONL).

This is the standard transport for local MCP servers, including:

Node.js servers via npx (e.g., npx @modelcontextprotocol/server-filesystem)
Python servers via uvx or python -m
Native executables built for MCP
