Use Authorization bearer token headers for public MCP endpoints.

Command

instatunnel 8787 --mcp --transport v2 --subdomain mymcp

Public endpoint example

https://mymcp.instatunnel.my/mcp

Public URL	https://mymcp.instatunnel.my/mcp
Local port	Use the port from your local app command.
Success check	Use Authorization bearer token headers for public MCP endpoints.

If the provider cannot reach the endpoint, confirm the local app is running and restart the tunnel with the same subdomain.

If events arrive but fail verification, compare the exact public URL and signature secret configured in the provider dashboard.

If retries create duplicates, store the provider event ID before performing side effects.

Start free, validate locally, and upgrade when you need MCP, higher limits, or advanced analytics.
