Function connectStdio

connectStdio(
mcpServerOrFactory: McpServer | (() => McpServer),
options?: { logger?: Logger },
): Promise<SetupStdioTransportResult>
Set up stdio transport for MCP server: connects the server to stdin/stdout for local CLI usage. serveStdio owns the era decision for the connection - the opening exchange (an initialize request pins 2025-era, a server/discover probe pins 2026-07-28) selects which instance from factory serves the connection's lifetime. Never pass legacy: 'reject' here: dropping 2025-era stdio clients (Claude Desktop, Claude Code) is not this package's call.
Parameters
- mcpServerOrFactory: McpServer | (() => McpServer)
  Either a ready-made McpServer instance or a factory called once per connection. A factory is what serves both protocol eras from the same definitions; an instance is served through a factory that always returns it.
- Optionaloptions: { logger?: Logger }
Returns Promise<SetupStdioTransportResult>
