MCP Hello Page

A company launched an MCP Server for their tool but encountered user confusion when customers visited the server URL in browsers and received a 401 error, leading to unnecessary support tickets. The developer solved this by detecting browser requests and returning an HTML page explaining that the endpoint requires integration into an MCP client, rather than direct browser access—a simple solution that dramatically reduced support inquiries without requiring the MCP specification to be updated or building connectors for multiple client platforms.
