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?

TL;DR
There is an issue with the appwrite-docs MCP failing in Cursor with an SSE 400 error due to no tools being loaded. User asked to be informed if the issue persists.
