Cursor IDE
Describe the Bug
Cursor does show progress but not logging messages.
Steps to Reproduce
from fastmcp import Context
from fastmcp import FastMCP
import asyncio
mcp = FastMCP("MCP server")
@mcp.tool()
async def long_running_task(ctx: Context) -> str:
"""Execute a long-running task with logging.
Args:
ctx: MCP context
"""
await ctx.info("Starting task...")
total = 5
for i in range(total):
await ctx.debug(f"Processing step {i+1}/{total}")
await ctx.report_progress(progress=i, total=total)
await asyncio.sleep(1)
await ctx.info("Task completed successfully")
return "Task finished"
mcp.run(transport="http", port=8999)
Expected Behavior
The tool call blob should show log messages along with progress.
