hermes - 💡(How to fix) Fix [Bug]: Official MCP server for Google Drive authenticates successfully, then always times out for any tool [2 pull requests]

Bug Description

I am trying to use Google's official MCP server to access my Google Drive account. After adding the Google Drive official MCP server in Hermes' config.yaml, I always get a timeout when trying to use any of the tools it exposes. Google Drive MCP server requires Oauth. hermes login says authenticated, it can do the tool discovery instantly, without showing the Auth URL mentioned here. I believe this is the main issue

I removed the MCP server once via hermes mcp remove, then added it again - no change. When removing it says it's cleaning the Oauth tokens: <img width="808" height="88" alt="Image" src="https://github.com/user-attachments/assets/4149a1f6-9019-487f-9888-d195114cd27a" />

When adding it back, via hermes mcp add, I obtained the screen below - note that utility does not support Oauth, so I needed to go back in the config.yaml and add the auth section manually:

In case it matters: before using this MCP server I did configure the google-workspace skill, authenticated with Oauth, then disabled it.

Steps to Reproduce

1. Edit Hermes config.yaml
2. Add this section (add the required identation):

mcp_servers:
  googledriveofficialmcp:
    url: https://drivemcp.googleapis.com/mcp/v1
    enabled: true
    auth: oauth

1. execute "hermes login googledriveofficialmcp"
2. observe that it successfully exits without any redirection URL as the documentation would suggest : hermes mcp login googledriveofficialmcp

Starting OAuth flow for 'googledriveofficialmcp'... ✓ Authenticated — 8 tool(s) available 5. start hermes 6. observe it's listing the mcp server

1. ask hermes to "show me the size of the first file from google drive"

2. Observe the mcp resource times out:

To have a proper Oauth workflow triggered
