appwrite-docs MCP fails in Cursor — SSE 400, no tools loaded

Hi team, I'm having trouble getting the hosted Appwrite docs MCP working in Cursor on Windows.

Environment

IDE: Cursor (latest)
OS: Windows 11
Node: v24.15.0
appwrite-api MCP works fine (3 tools, 1 resource)
appwrite-docs MCP fails consistently
Config tried

Official direct URL (current):

"appwrite-docs": {
"url": "https://mcp-for-docs.appwrite.io"
}
Also tried the mcp-remote bridge:

"appwrite-docs": {
"command": "npx",
"args": ["-y", "mcp-remote@latest", "https://mcp-for-docs.appwrite.io", "--transport", "http-only"]
}

What happens

Cursor connects to Streamable HTTP, then fails with Session not found
Cursor falls back to SSE
SSE returns 400
Server shows Error in MCP settings; sometimes it briefly looks connected but lists "No tools, prompts, or resources"

Logs: (see image)

Direct endpoint checks

POST https://mcp-for-docs.appwrite.io → 500
POST https://mcp-for-docs.appwrite.io/mcp → 404
POST https://mcp-for-docs.appwrite.io/sse → 404
Questions

Is the hosted docs MCP currently healthy? These errors look server-side, not config-related.
What's the correct Cursor config for Windows right now — direct url, or mcp-remote?
Is there a known issue with Cursor's Streamable HTTP → SSE fallback for this endpoint?
