Describe the bug

• I have built a remote server using the same codebase as described in the typescript-sdk readme: https://github.com/modelcontextprotocol/typescript-sdk/blob/main/src/examples/server/simpleStatelessStreamableHttp.ts
• But I cannot get this server to load at all on claude.ai
• additionally, from the documentation, the expectation is that it should be calling the POST method, but through my logs, I can see it's trying to call the GET method instead.
• even after updating it so that the POST and GET method do the same thing, it still doesn't function

To Reproduce
Steps to reproduce the behavior:

1. follow the steps to building the stateless server: https://github.com/modelcontextprotocol/typescript-sdk/blob/main/src/examples/server/simpleStatelessStreamableHttp.ts
2. expose the server via ngrok
3. add the ngrok server through the https://claude.ai/settings/profile page
4. check the console and the server logs

Expected behavior
it should pick up on the server and tools
