# MCP Inspector command fails with missing flags

If you run the MCP Inspector command copied from the **AI Agents** page and see "Method is required" or "Transport type not specified", the command is missing flags. For this link shape, the Inspector needs both a transport flag and a method flag.

Run it as:

npx @modelcontextprotocol/inspector --cli "YOUR-AGENT-LINK" --transport http --method tools/list

This lists the three available tools (search_listings, get_listing, check_availability) and confirms that your link is live.

To try a real query, replace the method with --method tools/call --tool-name search_listings. You can also drop --cli entirely to open the interactive Inspector UI instead.
