# MCP Simple StreamableHttp Stateless Server Example A stateless MCP server example demonstrating the StreamableHttp transport without maintaining session state. This example is ideal for understanding how to deploy MCP servers in multi-node environments where requests can be routed to any instance. ## Features - Uses the StreamableHTTP transport in stateless mode (mcp_session_id=None) - Each request creates a new ephemeral connection - No session state maintained between requests - Task lifecycle scoped to individual requests - Suitable for deployment in multi-node environments ## Usage Start the server: ```bash # Using default port 3000 uv run mcp-simple-streamablehttp-stateless # Using custom port uv run mcp-simple-streamablehttp-stateless --port 3000 # Custom logging level uv run mcp-simple-streamablehttp-stateless --log-level DEBUG # Enable JSON responses instead of SSE streams uv run mcp-simple-streamablehttp-stateless --json-response ``` The server exposes a tool named "start-notification-stream" that accepts three arguments: - `interval`: Time between notifications in seconds (e.g., 1.0) - `count`: Number of notifications to send (e.g., 5) - `caller`: Identifier string for the caller ## Client You can connect to this server using an HTTP client. For now, only the TypeScript SDK has streamable HTTP client examples, or you can use [Inspector](https://github.com/modelcontextprotocol/inspector) for testing.
