### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

Notion MCP is broken in Cursor 2.2.43 on macOS: after I click Connect and complete the OAuth flow, Cursor never loads any Notion MCP tools/resources (stuck “loading tools” / shows 0). Logs show repeated “Saving tokens” after OAuth completes plus transport errors (“fetch failed”) and occasional “No server info found” while trying to list offerings.

### Steps to Reproduce

1. Open Cursor 2.2.43 on macOS (Apple Silicon).
2. Open MCP settings and click Connect on the Notion MCP server ([https://mcp.notion.com/mcp](https://mcp.notion.com/mcp)).
3. Complete the OAuth flow in the browser and return to Cursor.
4. Observe that Notion MCP stays “loading tools” / tools never appear (0 tools/resources).

### Expected Behavior

After completing OAuth, Notion MCP should load and expose its tools/resources in Cursor.

### Operating System

MacOS

### Current Cursor Version (Menu → About Cursor → Copy)

Version: 2.2.43  
VSCode Version: 1.105.1  
Commit: 32cfbe848b35d9eb320980195985450f244b3030  
Date: 2025-12-19T06:06:44.644Z

Node.js: 22.20.0

OS: Darwin arm64 25.2.0

### For AI issues: which model did you use?

N/A (not model-specific; MCP integration issue before any AI/model usage)

### Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

</div>

One observation for why I believe this is related to Cursor, not Notion: Notion MCP still works fine for me with vscode/copilot.

I am also having the same issue tried on multiple different computers Windows and Mac.

Seems likely the problem is Notion-related because I’m getting the same problem with Claude (mobile and web and desktop)

> Since 2.0.75 Claude Code, both pure MCP or installation via Plugin do not work, …they lost auth and can't reconnect.
> Restarting Claude Code - do not help
> Reinstall of the MCP / Plugin - do not help
> 
> On fresh install - it asks for Auth, tells you that Auth was successful and you can close the window, but then \`Authentication successful, but server reconnection failed\`

### Steps to Reproduce

- Notion: Settings → Connections → Notion MCP → Cursor → Connect

- Cursor: Click “Install”

- Notion: OAuth Authorize

- Cursor: Notion - “Needs authentication”

- Cursor: Click “Connect”

- Notion: Connection prompt - Click “Continue”

- Cursor: For sometime (up to 1 min) keeps printing the “Saving tokens…” and the UI says “Loading tools…”

- Cursor: Reverts back to “Needs authentication”

Here’s a list of some:
