LATEST_PROTOCOL_VERSION is not set to "2025-03-26" #378
Description
Describe the bug
The types in the SDK show that the latest protocol is 2024-11-05 , but the new release supports Streamable HTTP. My understanding is that is only supported in 2025-03-26:
Line 3 in ac939a5
Because of this, we have to say our MCP server protocol version is 2024-11-05 to get the inspector to work properly, which feels like a hack.
To Reproduce
Steps to reproduce the behavior:
- Download mcp inspector
- Use a Streamable HTTP server that says the latest protocol supported is 2025-03-26
- MCP inspector fails to continue
