Describe the Bug

After upgrading from 0.6.10 to 0.7.0-rc, the Exa MCP Server no longer appears in the settings.

• A factory reset on 0.7.0 does show the Exa MCP Server correctly.
• This indicates the issue only occurs during migration from older versions.

Steps to Reproduce

1. Install 0.6.10.
2. Upgrade/install 0.7.0-rc.
3. Navigate to Settings > MCP Server.
4. Observe that the Exa MCP Server is missing.
