MCP connection is lost due to expired access token

[ashen-dusk]

Problem:
After the expiry of the access token, the MCP connection is lost.

Expected Behavior:
A new access token should be obtained automatically using the refresh token.

Proposed Solution:
Implement logic to use the refresh token to get a new access token and restore or sustain the MCP connection without interruption when the current token expires.

Impact:
Improves reliability and user experience when sessions time out due to token expiry.
