MCP Transport Streamable HTTP
- This mechanism suggests is designed to support over standard HTTP infrastructure
- request/response
- streaming responses
- bi-directional event-style communication
- tool execution progress
- long-running opertions
Building simple mcp server with Streamable http transport
-
Watch the video for steps
-
Create a simple python project with server.py, ensure
mcp[cli]package is added to venv
from mcp.server.fastmcp import FastMCP
mcp = FastMCP(
name="streamable-mcp-demo",
host="localhost",
port=18000,
)
@mcp.tool(name="add")
def add(a: int, b: int) -> int:
"""Add two numbers together."""
return a + b
if __name__ == "__main__":
mcp.run(transport="streamable-http")
- Now create a launch configuration
