It’s been like a week since agent just fails 100% of the time, so that implies I fully lost the MCP feature as a consequence too, this makes cursor not competitive immediately due said mcp loss, ETA for fix?

When you say that it’s failing, is it failing to call MCPs? Or is it just failing totally? Could you attach a video/photo of what’s happening?

It always says “unable to contact anthropic”; and does nothing. It’s been like this for like a week or so.

+1  
Same problem. Agent is not working failing to connect to Anthropic “check your vpn” message.

“Edit” mode works for some reason, but “Agent” fails 100% of the time and it’s been like this for days.

Didn’t have any apparent error but removing (besides the obvious agent failure 🤣)

```
"pandoc": {
  "command": "uvx",
  "args": [
    "mcp-pandoc"
  ]
},

```

made it work again 🫡🙏

You are right.

This is a huge bug.

After I completely removed all MCP servers, Agent started working again. I only had 2 MCP and once I completely cleared out the mcp.json Agent started working.

This is a pretty egregious bug!

My mcp.json was:

```auto
{
  "mcpServers": {
    "browsertools-mcp": {
      "command": "npx",
      "args": [
        "@agentdeskai/browser-tools-mcp@1.2.0"
      ]
    },
    "firebase-mcp": {
      "command": "env",
      "args": [
        "SERVICE_ACCOUNT_KEY_PATH=/path/to/firebasesdk.json",
        "FIREBASE_STORAGE_BUCKET=example.firebasestorage.app",
        "npx",
        "-y",
        "@gannonh/firebase-mcp"
      ]
    }
  }
}

```
