FAQ from springboot-MCPserver-JUnit

How do I configure the server for STDIO?

Use the provided Java command with the specified arguments, including -Dspring.ai.mcp.server.stdio=true and set the necessary environment variables.

How do I configure the server for SSE?

Point your SSE client to the server's SSE endpoint, typically http://host:port/sse.

How can I change the SSE endpoint?

You need to re-inject the ServerMcpTransport bean with the desired endpoint. See the provided code snippet for an example.

Can I have multiple endpoints for a single service?

Yes, you can re-inject multiple McpSyncServer beans. This is a more advanced configuration and requires further research.

Does the server support SSE authorization?

The MCP official protocol documentation has been updated with an authentication scheme, but Spring's implementation is pending an update.
