I ran this multiple ways, with docker, by using binary install. I keep getting 404 page not found.

My Grafana instance is running over the nextwork on http://:3000 and I use the following commands

GRAFANA_URL=http://<IP-A>:3000 \
GRAFANA_API_KEY=<Grafana-service-account-key> \
MCP_BASE_PATH=/mcp \
mcp-grafana -t streamable-http -debug --address 0.0.0.0:8000

time=2025-06-28T20:49:53.964-04:00 level=INFO msg="Starting Grafana MCP server using StreamableHTTP transport" version=v0.5.1-0.20250624132020-43a92b28b870 address=0.0.0.0:8000 endpointPath=/mcp

I keep hitting the following error:
